• Satellite Pro C50: Installation of Win 7 using the UEFI boot mode

  I want to install Windows 7 Pro 64 bit on Sat Pro C50 (downgrade if you like - comes with 8 win), but I want UEFI boot, with GPT partitioning.

  Definition of return to the UEFI boot and install Win7 boot media - hangs on "Starting Windows" screen

  I'm not convinced that it is a problem of Microsoft.

  Hello

  On Toshiba laptops, where the UEFI BIOS is available, it of necessary to disable secure boot and change the boot to the CSM mode in order to boot from external sources and install systems other than Win 8 or 8.1 Win

  Of the workarounds in the internet described the installation of Windows 7 in UEFI mode but I doubt that this will be possible on Toshiba laptops because the BIOS is different and modified for each series of laptop.

• Anyone got the DVD to the UEFI boot?

  I used the normal Wizard to download and allowed him to install supports for the upgrade of Windows 8.  The flash drive seems to work fine and boots by using UEFI.  The DVD does not work...!

  Anyone find this is the case?  Surely Microsoft would not put in place the DVD option to not allow to boot in a UEFI configuration...

  I looked quickly the directory structure and it seems to be OK, so I have to assume that there is something on the way is built the .iso image file, if it is a problem of Microsoft.

  Indeed, ISO created by the Wizard Windows 8 upgrade does not boot UEFI support. The files in the ISO are beautiful (file \efi), but the boot images are broken. To start in UEFI since CD/DVD mode, it must be a special boot image that allows to start the EFI boot in \efi\boot. ISO created by the wizard upgrade of Windows 8 has only the boot image standard for the normal BIOS boot mode, while the preview of Windows 8 ISO has two boot images, BIOS and UEFI mode.

  The solution is to build a new ISO file, with two boot images. Boot images are available in the ISO file system. I have sucessfully built ISO with the Microsoft tool "oscdimg. To obtain the tool, or download the evaluation of Windows and the Deployment Kit (ADK) from http://www.microsoft.com/en-us/download/details.aspx?id=30652 or download just the tool of http://blog.paulbetts.org/index.php/2011/09/17/converting-a-win8-install-directory-to-an-iso/
  In addition, mount the ISO file with a virtual DVD drive, or insert the DVD into a real DVD player. In the following example, it is assumed that the Windows 8 DVD is in drive g:
  Now, create the ISO fixed (including the UEFI boot image) with the command:
  Oscdimg.exe-o-u2-udfver102-bootdata:2#p0,e,bg:\boot\etfsboot.com#pEF,e,bg:\efi\microsoft\boot\efisys.bin g:\ d:\path\to\new\win8pro-uefi.iso m
  Burn the new ISO on a DVD file. I used InfraRecorder and boot from DVD in BIOS and UEFI mode worked well. Note: I have not tested a whole plant, but only until the first dialog box installation program.

• Satellite C50 - B with Win 8.1 - PXE error is displayed using the UEFI boot mode

  I have a laptop of C50 - b under Win 8.1 and recently needed to boot from a USB stick so finally found the way to do it (missing the start of the first bios menu) and managed to do.

  My problem is same when I returned in the uefi and set the boot order local drive, cd, network, he asks every time that I want to start PXE IP4, IP6 then IP4 and IP6 again. I also disabled secure boot

  I think that a value is missing, when I went to the BIOS and return to the start of IEFU option, but where is the laptop get the setting to tell him to network/PXE boot when the bottom of the list and the wake we LAN is disabled.

  Exactly, secure boot must be enabled in order to boot from the internal HARD disk where the 8.1 for Windows has been installed.

  If you want to boot from external sources (IE USB flash memory stick) you will need to disable secure boot.

• ACER ASPIRE E5-511-ADD DEVICE USING THE UEFI BOOT.

  Hello. I bought a laptop Acer Aspire with Linux preinstalled E5-511. I want to install windows 8.1.

  I created with Rufus TPG bootable USB flash with win8.1 image. UEFI mode the laptop does not recognize the USB, I have turned off secure boot, put the USB - HDD on the top of the boot priority but in vain.

  In legacy BIOS mode, I can boot and install windows, but the touchpad mouse does not work, only the USB mouse functions.

  How can I add UEFI boot USB flash?

  Thank you in advance.

  You did right, but sometimes the USB interfaces are not recognized by the system, I had some problems with a pair of USB pen which has not worked as a boot device, but another one worked smoothly.

  don't forget to have your HDD or USB pen in FAT32.

• HDD not found/detected when using the UEFI Boot

  I have a HP Sleekbook 15-b035tx, which came with a windows 8 OS already installed. a few reasons, I tried to quarterback to windows 7. After several unsuccessful attempts, I finally managed to install windows 7 by changing my boot for a legacy starting sequence.
  later due to lack of drivers for win 7, I installed, instead upgraded to win 8 running on existing startup (using the MBR if im not wrong). now, I want to install a new copy of victory 8 with UEFI, but the problem is when I change my boot sequence disable startup inherited, then installing win 8, I do not see my HARD drive ... im using a flash drive to install win 8 which is already in the UEFI (I used diskpart to do this).
  also, when I use legacy boot and try installing windows, then the HARD drive is displayed and when I format the HARD drive and create new partitions, he created 3 partitions (System, MSR), reserved and the fourth for the OS. I tried to install the windows like this, but after installation, when I change the boot sequence in the UEFI even once, it does not start

  now I want to install windows in the UEFI... and I really need help with this please ... I hope I explained the scenario... If someone wants to ask anything, please don't ... as I really need this out... and also, I would like to ask that how can I check if my HARD drive has been changed from MBR of GTP

  Hello:

  I can't find the specifications of product for your model - only these introduce yourself.

  http://h10025.www1.HP.com/ewfrf/wc/pfinder?cc=us&DLC=en&LC=en&tool=&query=15-b035

  They all have Intel hardware with an nVidia GT 630M graphics card.

  If yours has the same characteristics, you can install W7 64 bit there without too much difficulty.

  I know where all the drivers.

  If you do not see the HARD drive normally you must load the sata drivers.

  See if it works in uefi mode...

  Download the drivers from this link below (first or second file listed - 32 or 64 bit depending on the case).

  https://Downloadcenter.Intel.com/Detail_Desc.aspx?AGR=Y&ProdId=2101&DwnldID=23060&keyword=Intel+RAPI...

  Extract the files on a usb flash drive.

  With the flash drive and the installation of W8 media plugged into the machine, boot from the installation of W8 media.

  After selecting the install now option, select the training - Advanced menu, Options and select the option load a driver.

  You should now see the storage driver files listed.

  If you check the box, it only includes the compatible driver.

  Follow the prompts and I hope that the W8 should install.

  If this does not work, and no one else can help out you, let me know if you want to install W7 x 64 on and I'll guide you installed the drivers you need.

• Portege R200 cannot set on the BIOS boot sequence

  Hi all.

  Our R200 entered mode of hibernation after that the battery power is low, then by some unfortunate twist of fate, the battery got deleted accidentally. Now it does not start correctly because every time it displays a BSOD stating Unmountable_Boot_Volume.

  I could solve this problem easily by disabling the hiberfil.sys file, which is the reason for the BSOD, if only I could change the boot order. Unfortunately, enter the BIOS, I am only able to access the first page where the only editable elements are time, date, and passwords. Pressing Pageup and Pagedn does nothing. The BIOS is updated to the last appearing on this site.

  Pressing F12 or F2 when the toshiba logo and icons appear does nothing no more. It's a HARD disk 1.8 "and there are no adapters available in our region. I can boot from a CD if and only if I take the HD. But then, it is useless since I can't fix it like that. It is not recognized if I it reconnect after booting. When I reboot, it does the BSOD thing again. It is becoming a frustrating cycle.

  I scoured these forums for other ways to boot from the CD and apply the suggestions, like hitting 'c', nothing helps.

  Any help would be much appreciated.

  Thanks in advance.

• After the passage of the UEFI boot problem boot in legacy (V5 - 471 g ACER WINDOWS 8)

  Hello! I just change the boot settings in the BIOS to UEFI for Legacy (Windows 8). After passing them, I turn on my laptop and I see "Operating system not found" and "Media test failure, check cable of...» "Moreover, I use an Acer V5 - 471 G Windows 8. Please help me! PS My W8 is pre-installed.

  That's what I did...

  the same thing as you...

  to solve this kind of mess...

  First, you must download from the acer site, the last driver BIOS for your laptop.

  (use another laptop)

  but you need to install a single... but don't worry, it will ask you if the file you are trying to install is not necessary... I used version 1.22... (it depends on the version of the bios, the starting version number must be the same., mine is 1. xxx 1.22, I was invited that installing it is not fair, she says that it is incompatible)

  then, once you have downloaded, unzip it...

  Make sure you have it on a USB (usb)

  Second, since you have the Disc... use it...

  http://www.SevenForums.com/tutorials/139810-SFC-SC

  This shows how to go to the command prompt by using repair disk (this can be win7 is virtually the same, only gui is different)

  go to repair your computer option where you will find many options...

  Choose the option to open a command prompt.

  as your in drive X: that is the container for the discount, go to the current folder of the file...

  X: > F: (if F is the letter of the usb key, then F, if not, then use the corresponding to the USB drive letter)
  ... go to the bios folder
  F: > cd BIOS_Acer_1.22_A_A/BIOS_Acer_1.22_Windows/Windows

  then run the Update.bat

  (must be that your battery must be greater than 30 %..)

  If so, simply run the Update.bat

  F:/BIOS_Acer_1.22_A_A/BIOS_Acer_1.22_Windows/Windows > Update.bat

  just wait and voila... it's fixed

  mine is aspire v5 471g

  just tried the boot legacy... and f2 was (as expected... does not work)

  I just did what I said here and it worked again, bios has been returned to factory settings and I just sit here having a smiling face...

  Thus, a very big reminder...

  What happened, never turn your computer off by updating of the bios... just to be sure of something stupid happens

  If this does not work... try again the 2.17 sir...

  Unzip the exe file it y...

  After that...

  Locate the update.bat and then run...

• Vista boot sequence

  First of all, this is not a problem with dualboot OS since the answers I got do not help because either they do not know and feel that they need to type something
  or they can't read. I'll try to explain as simply as possible.

  When Vista starts it asks me what legacy to boot from (not the operating system) but the motto:

  HD
  SATA, which it starts the real
  DVD player
  Printer
  or leakage by default startup

  If I take the SATA, everything is fine and runs as well as it always has. I'm tired of having to choose each time.

  I tried;

  Reset in the BIOS boot sequence - they are all in parentheses which I know isn't fair but can find no option to change

  The Vista repair option install disc-do not ask again each time

  Guest/Fixmbr/fixboot or prompt Boot boot responds

  About 6 different 'Windows fix forums' nobody did allow that the answers are always the same: Vista repair option (each of them swear blood he will fix it)
  even after telling them that I've tried) explain how to dualboot OS has nothing to do with the question.

  It gets frustrating because this forum is the last of them, I'll try. The machine works great as it always has, but waiting to choose the currency

  is getting old.

  Hello spooky24,

  Your explanation is clearly a problem of hardware (BIOS) setting. This is not a problem of windows and the experts and volunteers here, will continue to try to help you! Since this is a unit built car, I suggest that you contact the motherboard manufacturer for help with their Board because they did, not Microsoft. Hope this helps you. Let us know anyway. Make it a great day!

• CRC of the MBR or UEFI boot loader changes at each reboot?

  I have a Fujitsu Esprimo desktop running Windows 7 Professional.  Whenever I restart, it stops before loading Windows with the following message:

  "The CRC of the MBR boot drive or the UEFI boot loader has changed since the last system startup.
  Press a key to enter setup. »
  To continue, I need to go into the BIOS Setup, output without any change, then Windows loads normally.  This repeat on the next reboot.
  I have run chkdsk on the drive system (c :)), and no problem not found.
  What would do this, and how can I change it?

  I have never activated this setting on my laptop. I don't know exactly what it checks - if it's just the MBR or other things like Bootmgr and BCD. On a system with only Windows 7 installed, I don't expect the MBR and Bootmgr to change after installation. If this started after an update? Reliability Monitor may show changes with has occurred around the time it started.

  I guess that the Fujitsu support have verified that you have the most up to the date of the BIOS. Have you tried to disable the warning of viruses and then allowing him once again in which case it must be reset? Even if it is a boot virus, I don't expect to be changing in order to cause the detection at each start. If you want to eliminate this possibility, it is preferable to use a virus scan offline as Windows Defender in offline mode.

  An outside possibility is that Webroot is something clever with these files that is causing the problem.

  You can reset the MBR and Bootmgr using the method here:

• 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.

• How can I set up the DVD player, the 1st boot priority?

  I don't know hoe to set my PC startup to restart from the DVD player. I have a product recovery disk, but not to make my PC open system restore. Help, please.
  I changed my system registry uxtheme.dll and this problem started occurring.

  Put the DVD in the drive and start it.

  You may need to change a BIOS setting to make the first boot device, a DVD/CD player. To do this, when you turn on look for a configuration message indicating what key to start typing - F2 and del are commonly used. The message appears for very long and it you miss, you have to restart the computer.

  In the BIOS, look for a section that contains the boot sequence, change to CD/DVD, save it and let the computer to restart. In addition, some pre-installed systems have another key (usually F12) that allows the user to open the start menu rather than change the BIOS boot sequence.
