• Z580 UEFI boot problem

  Hello everyone,

  I recently bought a Z580 (product number 59362732), provided without a pre-installed operating system. I installed a Crucial SSD (instead of the HARD drive) with success and replaced the DVD drive with disc HARD original.

  After installing Win7Pro and all drivers provided on the SSD (UEFI boot is set to on, SATA AHCI mode prior to installation) I am facing a strange startup problem - it seems not every time, but the laptop often just hangs after the Lenovo logo disappears and restarts itself and, as if he could not find the partition to boot from. However, in the configuration of the BIOS, everything seems normal - it recognizes both of my drives. This problem appears on the two UEFI on and off the start, but strangely, Windows starts without any problem after activating/deactivating the UEFI BIOS Configuration option - it doesn't matter if the activation or deactivation. I have searched for the solution on the Internet but haven't found any solution. Any help would be appreciated.

  Thank you, feki1409

  Hi Zoltan,

  Thanks for your advice in the first place! I tried to update the firmware, but it failed at some point during the installation. As I looked at the site of Crucial, the update is not guaranteed to work on UEFI/GPT disks, so I'll have to wait until the right driver is started.

  However, I tried to fix by using the EasyBCD utility startup files, as a friend advised me. The problem does not appear since then (4 start-up), so I hope that this is resolved for now. It was probably caused by my fault during the installation/system tweaking. I'll definitely keep you posted on this.

  Thanks again,

• Aspire 5742-6798 UEFI boot problem

  I have an Aspire 5742-6798 provided with Windows 7 installed.  Someone tried to upgrade to Windows 8.

  Now, the laptop isn't even trying to boot from the hard drive. It goes directly to the initialization of the network.

  I started from the 8.1 Windows installation media and clicked on "computer repair". I tried a reset, which has almost immediately. Discount did the same.  I went with Options in advance and went to a command prompt. bcdedit gives:

  "The boot configuration data store could not be opened.

  The requested system device cannot be found. »

  DiskPart displays all partitions and volumes, normal and healthy.  volume of the list shows:

  Acer volume 1 C NTFS Partition 579 GB healthy

  Hidden 2 RECOVERY NTFS Partition 600 MB Healthy volume

  Hidden 3 ESP FAT32 Partition of 300 MB Healthy volume

  Volume 4 Partition 15 GB NTFS healthy hidden button

  So I would like to boot from the recovery partition, so I can restore the default out-of-box laptop.  I suppose one of these partitions would do what I want.  Car-Alt + F10 does nothing to start.  Hard disk is configured for TPG.

  How can I select a partition to boot from?  I know that I did a time, years; but I don't know how I did it.  The fact that the laptop uses UEFI change everything?

  Thanks in advance.

  Someone please mark this resolved.

  I'm a fool.

  The laptop isn't UEFI.  This is why I couldn't manipulate the GPT disk.

  Sorry for wasting time in person.

• 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...

• USB boot with UEFI charger problem

  Hi peepz I have a desktop HP 110 009el and I am trying to boot from USB on the UEFI boot loader, checked the bios and installs on top saves USB the changesand hit F9 to restar PC.

  the only options I see to restart on UEFI boot its only are the network bootloader... no USB or HDD doesn't appear...

  any ideas how boot USB charger UEFI?

  just to let is know I did installed USB no UEFI under Linux and tryied to install win7...

  the two worked great but wasn't UEFI.

  Thanks in ADVANCE!

  Hello

  Power off with the active UEFI USB device inserted into the PC. Now, turn on the PC and press ESC then press F9. The USB device should now be indicated by EFI.

  Most active UEFI PCs I've used require UEFI enabled devices to be connected to the current time in order to be recognized.

• Satellite L50D - Boot problems after replacing the hard drive

  I just upgraded my hard drive of the pathetic crod 5400 they provide to a SSHD@7200rpm, but now have a major issue.

  I initially image the operating system from the old hard drive to the new drive and have had chronic start-up problems (1-3-4 attempts to start to succeed if it fails at any time (often to the Toshiba start screen)).

  I reinstalled from a drive under Win 8.1 plain own ENT (trying to avoid the bloatware) and it is exactly the same number and is what I used to format the laptop very well with previously and had previously worked.

  I tried reformatting and reinstalling (by removing all partitions on each attempt) to the CSM, unsafe UEFI and UEFI secure. MCS is a straight line never works not proceed and both UEFI methods have the same exact result.

  I tried with original restore disks and it seems to work (not had time to fully test) but I don't want the bloatware and it shouldn't be serious since, if I were a customer who forgot to make restore disks (too often) and just have to have a failed hard drive or replaced sacrificed the laptop would be now a door stop.

  This seems as bad as Apple to lock people in.

  So I would appreciate ideas of people to please, I don't know if there is a program that is supposed to take place on a new drive as PS3 etc (I doubt it), but that leads me into the wall, and will be the last time that I consider Toshiba as anything other than a joke, if there is no solution.

  I had to replace the hard disks many times in my previous Toshiba laptops and were devoid of this crod, it has something to do with UEFI which seems more a nuisance than a help right now.

  TIA.

  Hello

  In my opinion, you should first check if the startup problem is related to the new installed HARD drive or new installed system.
  You said that the laptop fails to start up often to the Toshiba start screen.

  The splash screen appears during the POST (power on self-test) procedure. During this test, the material will be checked.
  I m wondering if the hybrid SSD/HDD isn't recognised by the BIOS during this particular step.

  From my point of few, this could be the reason why the system cannot be started.

  Another important note:
  The 8.1 win requires enable start secure as well as the UEFI boot mode.
  Therefore, you must enable both options in the BIOS.

  Last but not least check if you are using the latest BIOS version as latest firmware for the hybrid SSD/HDD

• 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.
  I'm happy wipe existing partitions if that solved the problem.

  I have disabled _have_ Secure Boot.
  Win 8 install DVD boot works;
  CSM boot and boot from Win 7 DVD works - but this is not what I want.
  Definition of return to the UEFI boot and install Win7 boot media - hangs on "Starting Windows" screen
  Media _is_ good, works well on the PC manufacturers.

  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.

• 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.

• [Inspiron SE 7720] UEFI boot from USB does not work

  Hello

  I just bought a Dell Inspiron 17R 7720 special edition. It came with a Windows preinstalled 8 (up to 64 bits and mandatory boot UEFI). I want to use Linux (specifically, Archlinux) for the work and Windows for games, so double boot is necessary.

  I'm almost finished installing Linux except for the boot loader: I need to start Linux from UEFI and has failed to do so far. Here's what I did after I got the PC:

  • Secure Boot disabled;
  • updated the BIOS to the version A12 (maybe I shouldn't...);
  • resized the main Windows partition and created a few partitions for Linux;
  • legacy startup mode and managed to start an installation of Archlinux MBR bootable USB drive.
  • most of the system installed
  • switched back to UEFI boot mode, Secure Boot off.

  At the moment, I needed the UEFI kernel startup Setup Bootstrapper to have access to the EFI environment variables. So I created an installation of Archlinux UEFI-bootable USB drive (with a FAT partition) but so far I could not able to boot successfully to this car of UEFI instead of Windows 8.

  I think I tried every single combination, such as:

  • different USB ports;
  • different startup entries created with F2 installation boot, with different parameters.
  • different commands for start-up entries;
  • has hit my startup entries directly in the F12 boot menu.

  Anything in the startmode of the system always the Windows partition UEFI.

  Also, I couldn't find any relevant documentation manual or software on the A12 BIOS on the Dell site, I missed something?

  The solution that the user described in this thread for UEFI boot on a DVD has not worked for me with a USB key.

  If anyone had the same problem or has a solution or even information about it? UEFI is really starting to give me headaches on this machine!

  Thank you for reading.

  Try to go into the Advanced Boot Options.   Hold down the SHIFT key while as a RESTART to win 8.  This will get you to a page that will have an option called "Other devices" (from memory).    Choose that and you will have all features of the device as USB. First of all give it a try and I'm sure there is an easier way to start Linus directly more later.

• 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:

• 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.
  Have fun

• UEFI boot

  I have an E130 with Windows 7. It is the pre-installed lenovo system and it ist installed mode non-UEFI.

  I would like to install a Win7 64 bit with UEFI boot fee. But if I change the boot method in UEFI only, it will not start up key USB USB-drive oder.

  I just do:

  -install the latest BIOS 2.52

  -J' followed the instructions for making a USB bootable for UEFI

  -J' disabled startup security

  When I boot with only UEFO, I see a start menu and can choosw the USB - cd or the USB drive as a boot device. but nothings happens, if I press Enter on these points. Only in legacy mode the two mediums will start correctly.

  Any ideas?

  Thanks, Bernd

  I don't always know the reason why boot from the original DVD of Windows 7 x 64 does not work.

  But I solved the problem with the usb key. I've renamed the bootx86.efi in bootx64.efi and everything works.

  Thanks for your ideas.

• New SSD UEFI boot [U430 touch]

  Hi all

  My Lenovo U430 touch came with a Samsung 128 GB SSD.

  As it became a bit on the small side, I decided to replace it with a Samsung EVO 250 GB SSD.

  My first thought was to clone the old SSD and then resize partitions later. I quickly ran into trouble, the cloning has not worked. So I decided to start from scratch. So, I installed the new SSD and installed a Windows Pro 8.1 installation naked.

  Although everythings works one thing is still bugging me.

  For the new Samsung SSD to be bootable, I must:

  -Disable secure boot

  -Allow the start of the legacy

  Why is this?

  I thought about all the necessary codes were a BIOS / OS thing?

  * This was done a few months ago, it came just once again that I upgraded my BIOS and the laptop don't boot *.

  Thanks in advance for any suggestion or help

  well done secure boot part of the key of Windows 8/8.1 that is embedded in the bios and check the boot image, so if you install windows 8/8.1 pro or normal CD it will give the error box saying non-secure OS detected which means that it rejected your copy unaudited operating system which is not verified in secure boot so that the why it must be turned off.

  Reason 2: for UEFI only works if you have a bootable UEFI your ona windows USB key copy, so it can use UEFI and GPT instead of MBR since MBR mode only works in legacy mode and no UEFI, for uefi to work you gota difficulty one copy USB windows 8/8.1 with rufus and select UEFI & TPG box and then hit create so it will iso copy USB as a device of UEFI boot so it can use the UEFI
