Install Windows 7 on Windows 10 UEFI

I use a PC of R3 Alienware X 51 64 bit with a UEFI firmware. It is originally came pre-installed with Windows 10, but I want to perform a clean installation of Windows 7 on it. I have the DVD 64 bit and the product key for Windows 7 Ultimate SP1 and everything, but I still don't know how to install this on PC UEFI. Can someone here help me with this? Thank you!

  • Z820 - BIOS updated to v2.55 - cannot start or install the installation of Windows 7 (UEFI) disc

    Hello

    I have serious problems with the boot and install Windows 7 on my Z820.

    My problems started with Windows Boot Manager, throwing an error in the boot, saying that "the Windows Boot Configuration data file is missing required information". In the end, I decided to do a full clean reinstall of WIndows. However, I was unable to get Windows 7 installed. I was able to boot the disc at retail of Windows 7 64-bit UEFI mode, but he had problems with the installation. Each attempt ended with an error stating that 'Windows could not update the configuration to start the computer. Installation cannot continue. ».

    It was the BIOS v2.08. Intel 520 (240 GB) SSD as boot drive and 2 TB SATA HARD drive as data disc on the ports of controller LSI 2308 0 and 1 respectively. 2 DVD players on Intel AHCI ports.

    I decided to take a different path.

    I removed my data HDD and a DVD of the Z820 player. I put my SSD (which will become the startup disk) and a DVD player on both ports to AHCI.

    I've updated the Z820 BIOS with the latest version (v2.55, February 13, 2013), did a reset CMOS (machined cable disconnected) and reset the BIOS to factory default settings. Then, I put 'OptionROM mass storage' mode EFI and the storage on AHCI mode.

    Now, when I put in retail Windows 7 SP1 64-bit installation DVD and select the drive of DVD (UEFI) to start, I get just a flashing dash. I noticed also that some fans begin immediately turn faster.

    To summarize:

    I am unable to boot Windows 7 SP1 64 bit DVD installation detail at all and therefore impossible to install Windows 7.

    Configuration of the system (as in the last installation attempt):

    -Dual Xeon E5-2680

    -32 GB OF RAM DDR3-1600 PC3-12800

    -240 GB SSD IDE AHCI Intel oucederomsurlesecondport 520

    DVD player - Harbour AHCI

    -NVIDIA Quadro 4000

    -BIOS v2.55 (OptionROM in EFI, Secure Boot disabled mode mass storage)

    I'm getting desperate... ;-)

    Should I try reseating the RAM modules? Remove some RAM? Connect my monitor differently (currently DVI to VGA)? Replace the graphics card?

    Kind regards

  • Clean install Windows 7 with UEFI in dv6-7215nr

    Hi, I would like to do a clean install of my HP dv6-7215nr Windows 7 Enterprise SP1 x 64 envy laptop.

    To this end, I have 3 questions to solve some installation issues.

    1. What are the steps to clean install Windows 7 SP1 Enterprise intact in UEFI mode?

    I tried to install Win 7 after the pre-requisites following:

    (a) not partitioned 200 GB free space on the disk (only 1 physical disk)

    (b) already installed Windows 8 files with UEFI

    (c) UEFI enabled

    (d) heritage disabled startup

    (e) secure boot disabled

    When I Boot in UEFI of CD/DVD, I can't switch to the Windows startup screen, it just hangs. What I am doing wrong? Is there any other prerequisites that I don't know?

    I tried to install UEFI with Legacy enabled Boot, and I installed win7 but I can't disable Legacy new Boot because Win7 boot and I want only the UEFI Boot and need for inheritance disabled.

    2. where can I download drivers for Windows 7 for my laptop?

    I found this topic:

    http://h30434.www3.HP.com/T5/notebook-operating-systems-and-software/HP-envy-DV6-7210ei-downgrade-fr...

    They point to these drivers

    http://h10025.www1.HP.com/ewfrf/wc/softwareCategory?cc=us & dlc = in & lc = in & product = 5273735 & task = &

    I think I could use these drivers, but I need just in case where. I guess they should work as the product names are roughly similar (with mine).

    3. is it possible to Secure Boot with Windows 7 SP1?

    I have no research on this so far.

    Thanks for the help that someone in the community can give to me, it is not important all the problems that I have set in I can still do research on questions 2 and 3 and help others with my research if I can do it before a response. Any info you can give me will be too great.

    (1) ' secure Boot' must be DISABLED and 'Legacy Support' must be ENABLED to install Windows 7 and many other older operating systems. The bootable media must support UEFI boot to install on a GPT-partitioned drive.

    You let people with DISABILITIES 'Secure Boot' (and 'Legacy Support' ENABLED) once you have installed Windows 7. Changing these options causes Windows 7 to start is no longer.

    (2) the Windows 7 drivers on the CTO Entertainment Notebook PC drivers HP Pavilion dv7t-7000 page you referenced, will work on your computer.

    (3) it is not possible to install or use Windows 7 with "Secure Boot" ACTIVE.

    WARNING *.

    HP does not recommend installing Windows 7 on a consumer computer comes with Windows 8, and it will support the installation of Windows 7. HP cannot provide the drivers for Windows 7 and the appropriate drivers are not available for the hardware in the computer. In addition, Windows 7 can not take in charge some of the hardware or software designed for the computer.

    Make sure you create your media recovery HP or USB Flash Recovery discs before you edit or change anything.

    You will need to DISABLE 'Secure Boot' and ENABLE 'Legacy Support' in the 'Configuration of the BIOS start-up secured' on the page parameters below, until you try to install Windows 7.

    In addition, as the hard drive is probably partitioned as TPG, you must start the computer by using the "UEFI - CD/DVD drive" or "UEFI - USB Flash drive" options in the boot menu "F9". If "UEFI - CD/DVD drive", "UEFI - USB Flash drive" or something to that effect does not exist in the start menu, please post a screenshot and/or make startup listed options.

    I suggest using Windows 7 SP1 for the best installation experience. If you need Windows SP1, see 'How to install Windows 7 without the disc' to download and create your own disc of Windows 7 SP1. If the DVD does not start as UEFI, you may need to use a USB Flash drive (can ask "Quick start" DISABLING in BIOS) as the installation media. Please download the Windows 7 USB/DVD download tool to create a Windows 7 SP1 USB Flash drive. Please note that some computers may not recognize a valid active UEFI USB Flash drive if it is formatted in NTFS and may require only a FAT32 formatted USB Flash drive. You should be able to make a FAT32 formatted Windows 7 installation USB Flash drive using Rufus, UNetbootin, Universal USB Installeror WiNToBootic. I like Rufus, because it contains options for 'Plan of GPT partition for UEFI computer' and 'FAT32'.

    If you have missing or unknown devices after installing the drivers, please post to the "Hardware ID" Device Manager (just the text string will do) to these devices as shown in the example below.

    If you have any other questions, feel free to ask.

  • Install Windows 8 (using UEFI)

    HELLO EVERYONE

    So I bought this new laptop that is (ENVY HP DV7-7210ex)

    The first problem is the system was very slow and it freezes a lot. Once a week started showing fails (BLUE SCREEN)

    I contacted Microsoft. They told me to update the system. but the same problem appeared.

    So I bought a NEW VERSION of Windows 8 PRO, but when I tried to install it using UEFI, he couldn't start the setup and he showed me a message (THE SELECTED BOOT DEVICE failed). So I went to LEGACY BOOT. Windows 8 PRO is installed PERFECTLY. It works like CHARM and Super FAST...

    EXCEPT there is a problem that is: windows takes a long time to start.

    So I want to find a way to REINSTALL WINDOWS 8 PRO using UEFI

  • Cannot install Linux alongside Windows-8 (UEFI)

    I have HP pavilion 23-b026 all in one PC, which came with pre-installed Windows-8. Now, I want to install Linux alongside W - 8. (There is unallocated space on the disk about 250 GB)

    But when I try to boot from Linux-DVD, BIOS allows system to be booted from the DVD in EFI mode. He always assumes legacy mode (non - EFI) for DVD to boot. Therefore, I'm unable to install & start Linux.

    The error raised is:

    ERROR: No boot disk was detected or the drive failed.

    BIOS has no option to start EFI for CD/DVD mode.

    Is there a way out?

    Thank you.

    I had a similar problem.

    You have the ISO? If so, burn on the USB.

    I could not start CD/DVD, but was able to boot from USB and install a Setup to dual-boot with UEFI BIOS on a pavilion of 1380t H8.

  • Install Windows 7 Pro 64 bit with UEFI mode

    Hello world! So I'm here to talk about the installation of Windows 7 for the UEFI mode and I know a lot of people said it stucks on "Starting Windows" during installation, but I have a few question that my opinion:

    1. If a hard disk has come to Windows 8/8.1 with OEM or retail as installed, it should disable Secure Boot?

    2. If Windows 7 it remains stuck, the solution most is all in a hard drive format after Windows 8/8.1 backup partition and install Windows 7 with UEFI without getting stuck? I need to install it with TPG...

    Hope will understand. ;-)

    Secure boot is integrated in the firmware, not the installation hard disk.

    You can just boot from the installation media and format the hard drive.

  • Upgrade SSD and allowing the UEFI again after you install Windows 8

    Hi, having a problem w / install Windows 8 on 128 GB SSD using boot inherited (to easily boot from CD/DVD) and then return to UEFI boot sequence. Model is Dell Inspiron 17r SE. I'm absolutely not an expert on the terminology and technology, so I hope that I am using the correct terms. I removed the 1 TB disk that was originally shipped w / to settle more easily. I am able to install correctly to win 8 to the new disk (using a disc Dell win 8). After I reboot and try to come back back in the UEFI, I get a reboot constant return to the menu of the BIOS/legacy/Windows, UEFI, parameters, Diagnostic Boot Manager. Windows 8 will start only if Legacy option or boot first hard drive is selected. I DO NOT have the msata SSD, so my problem is not in the driver problem intel matrix (or whatever it's called).

    I looked at the PDF of installation of windows 8 in the wiki and forums and basically tells you to put the computer in legacy mode and install Windows 8, it does not say you can return to the UEFI boot. The only thing I do not according to who download drivers SATA on USB/add iso and loading them to install. That would be the question? I wouldn't guess.

    I have also tried to hit SHIFT + F10 to install and enter Diskpart, select disk 0, Clean, convert the GPT and exit and then the installation. No change. Am I supposed to completely install Windows 8, go back to install the drive, do the SHIFT + F10 sequence and then install then it would convert my GPT disk? I would assume install Win 8 would like to ask if you had UEFI and law/format accordingly.

    Questions or comments, please let me know. I would like this mode to get started more quickly. It's fast now through the bios boot, but I wish it were through the UEFI.

    When you use the legacy mode to install Windows 8, your setup application assumes that you want to format the SSD as a MBR disk.  That's why your system keeps jumping from UEFI.  Try to remove your current partitions (the disk must be empty to start), change your mode UEFI system configuration option and using the F12 boot menu a time.  Your computer must have an option on this menu to start your DVD/CD drive UEFI mode.  When you reach this point, remember to select the option to format the drive as a GPT disk.  UEFI mode can manage data the MBR and GPT disks, but if you want to start to UEFI, I'm sure the system drive must be a GPT formatted the player so that there the UEFI boot blocks.

  • Re-install Windows 7 on a machine with a UEFI interface...

    I tried to install Windows on a machine with an EFI interface that seemed to go OK.  But after reboot half dozen is back to a member base disk and is no longer using the EFI interface. What I am doing wrong?  I enter diskpart and wipe the drive. convert the GPT disk, and then create the following partitions. I create partition EFI, MSR partition, then a primary partition takes the rest of the hard drive. I restart the machine after the creation of my partitions so that I can boot from the Windows 7 DVD in UEFI mode.

  • Bypass UEFI provided the product key to install Windows 8?

    Just bought an HP computer brand new.

    Unlike my old systems, it is running a UEFI (BIOS) firmware and HP integrated the product keys for Windows 8 BASIC in the firmware somehow.   The problem installing my authentic copy retail of Windows 8 Professional.    I want to talk about a new installation DVD, after formatting and partitioning the drive (can't stand all this HP bloatware/test stuff).

    The DVD mode of UEFI boot work, but when it gets to the part of the facility where he asks my product key - windows install grab the keys off the coast of the motherboard and told me that they do not match.    I'm never gave the possibility to use the key that came with my copy of windows 8 pro.

    How to install Windows 8 Pro, so the installer will allow me to enter my product key?

    In the bios, there are options to disable secure boot, enable and disable the keys.   None of them running.   There is even an option in the bios by default to 'keys provided by the user.   but who doesn't either.

    Help!

    Found a working solution... just in case someone else runs into an OEM computer that has built-in product keys it UEFI firmware.

    The solution was very simple and easy to perform.    First you'll need an original copy of your Professional 8 Windows DVD or an ISO of it.    You will also need an empty key USB 4 GB or more.

    By following the steps on this site - perform the format of the USB key:

    http://www.Blogsolute.com/create-Windows-8-USB-bootable-pendrive-UEFI-boot/25988/

    Then create a file named PID.txt (as described below).

    http://www.Blogsolute.com/Windows-8-clean-installation-product-key-do-not-match/25990/

    After many hours of banging my head against the UEFI firmware, PID.txt solution works very well.   When windows setup find PID.txt, she uses this product code and ignores the one integrated in the firmware of computers.

    Don't forget to complete the formatting of the USB for UEFI, its necessary for the needs of secure boot of many new computers.    You can try booting in legacy mode, but it wouldn't work on my computer.

    See you soon.

  • X1C Windows 7 UEFI install without possible MSC mode?

    Hello

    I recently bought a Lenovo X 1 carbon and, after a brief tour in Windows 8, decided to install a clean Windows 7 on the computer. I managed to install Windows 8 in UEFI BIOS mode without CSM compatibility (and secure boot).

    Today, I tried to install Windows 7 without compatibility CSM and secure boot UEFI BIOS mode. When I tried to load Windows 7 (SP1 slipstreamed) installation from a USB bootable FAT32 stick, "grey bar" initialization worked very well (that is, the data is read), but the configuration hung on "starting windows" (tried 3 times); I tried one of the security modes and the system stops reports charge the filesystem to "classpnp.sys.

    Then, I went back to the BIOS and enabled the CSM (still only UEFI) compatibility. With this setting, I do install Windows 7 without any problem, and I installed it on a GPT partition. After installation, I installed all the Windows 7 updates and offers drivers also updated the X 1 drivers of carbon through Lenovo system update. Then, I tried to disable the CSM and restart, resulting again in the system to get stuck at the "starting Windows", as when trying to install.

    Have anyone of you installed Windows 7 with UEFI successfully and without active CSM? There are the "stuff" that can be applied to make this work? Note: the only advantage that I expect to get it to work is the "most beautiful watch" UEFI "BIOS" screen

    BIOS version is 2.03. Any suggestion is appreciated.

    There is no solution for this.  Win7 video drivers require the CSM, even using the UEFI.  The video driver will not work correctly if the CSM is disabled.  If you want to use Win7 on your system, you must leave the active CSM.

    Admin edit - see the KB article with additional details about the BIOS settings for the Win 7 startup on UEFI models.

  • Install Windows 7 on an iMac without Apple software

    I have 'experimented' with the installation of Windows 7 on iMac (20-inch 2.0 GHz Core 2 Duo, IIRC) mother and managed to enter an insensitive State and I'm trying to understand why. In short, the objective here is to determine how to install Windows 7 on an iMac (starting with a blank hard drive).

    A little history: MOM (and me) didn't like the Apple OS, so she was fortunately in Linux (CentOS 6) for a couple of years, but for various reasons, she now needs Windows. In the past, I installed Linux and Windows on anything and everything with a CPU, largely without major problems (so far). To clarify, install Linux was fine on this iMac, only Windows turns out to be difficult.

    One thing that seems to cause me a lot of trouble, is that - as I understand it: it's hard / cannot access all the options start at low altitude on an iMac (for example usual UEFI / BIOS stuff). Is this correct, or am I missing something?

    Another issue I have is that almost all the information that I find online made the assumption that the Apple OS is installed. This is clearly not the case for me - I've invested in Snow Leopard, a long time ago, but quickly decided it wasn't for me, erased the hard drive, installed CentOS and released the Snow Leopard installation media in the desert.

    The question I'm stuck, is the Windows 7 Installer refuses to install on the hard disk. He creates with happiness and format a primary partition, but gives the following error:

    Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Make sure that the drive controller is enabled in the computer's BIOS menu.


    If I could have access to all the low-level boot options, then maybe I could investigate this matter. Can anyone offer advice?

    Here is the optimal solution to the problem: buy a Windows computer. They are cheap. A Mac with OS X installed can run Windows using Boot Camp Assistant for a system dual-boot. Only then do you get drivers Windows requires to be used with Apple hardware.

    I intend loading Windows 7 on my new business PCs are there any settings I need to change? What should I know?

    Hey Bill,.

    Windows 7 can be installed on most recent business PCs. There are some requirements and parameters, as you should be aware.

    • First of all, you can not install Windows 7 on a computer with a 7th generation of processor.
    • You must change the version of the TPM secure on the PC or install a fix from Microsoft.
    • You must use the legacy (non-UEFI) mode in the BIOS.
    • You need your own copy of Windows 7 and a license for Windows Professional 10.

  • Satellite M50D - A - 10 L - installation of Windows 7 UEFI

    I m trying to install Windows 7 on TOSHIBA Satellite M50D - A - 10 L with UEFI boot.

    First time I used facility with CSM Boot EFI and it worked fine.

    But after I tried to spend in UEFI and make the installation of UEFI, whenever it starts loading setup files and after freez windows on "Starting Windows" screen.

    I have two pieces of these ultrabooks and they do the same thing.

    I used Flash disk, USB CD-ROM, two different versions of windows 7, but it have same endpoint...

    Secure boot is disabled

    I've got a Satellite M50 - A model (its similar to the M50D-A, but it was equipped with instead of ATI GPU nVidia GPU) and able to install the Windows 7 change the start mode MSC mode.

    Generally the UEFI boot mode can only be used for the system support UEFI as Win 8 or 8.1 win and some Linux distributions.
    Win 7 isn't taking system support UEFI.

    However, there are various workarounds to install Win 7 64 bit (not 32-bit) in the UEFI using the partitionstable GUID (GPT). Win 7 64 bit only contains the UEFI boot loader.

    But, very important is that UEFI installation isn t available (by default) is booting from USB due to lack of uefi boot loader! In case you use the key of USB for installation, you must add the UEFI (search in google for details) Start menu.

    Finally and above all depends on BIOS support in the case where the BIOS would only mode Setup CSM; all of these solutions workaround would be unnecessary.

    >. I'm tired of clean install - does not work

    To install Windows 7 on the laptop of Win8, you must change some settings in the BIOS.
    First of all, you have to disable startup secure in the BIOS.
    Second pass of the UEFI BIOS for the CSM and save the changes.

    Now you should be able to install Win 7

    But before doing this, I recommend that you create the recovery media (Flash disk to USB memory or recovery Toshiba

The internet went through Ethernet cable direct to the modem. I have reset the modem, but it is not getting an IP address assigned to the NIC card. I tried to force an IP address to be assigned, but it still does not work.

    How can go back us to windows 10? I tried HP restore, but it only shows options for windows 8.

    Help, please!

    Thank you!

    Since Win8 is out, embedded OEMs their product keys in the UEFI firmware on motherboard - and stopped including print on stickers on the PC.

    You can reinstall Win10 by install media from this link: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10

    Because your PC is already registered for Win10, if you get a window asking for a product key, just choose the option to ignore that.

    After Win10 is re-installed and connect you to the Internet, the PC will be automatically reactivated.

    Good luck
