I recently upgraded my machine from a z87 platform to an X99 platform (specifically the Asus x99 Deluxe + 5930k), and when I went to transfer my old SSD containing Windows 7 Pro x64 to the new build, (no surprise) it blue-screened on me with a 0x0000007B. However, unlike the other persistent BSODs I've received in the past, this one's truly stumped me. It seems that I am unable to boot Windows from the SSD in the new x99 build, but when I remove the SSD and place it back into the old build, it boots just fine...

Things I've currently tried (may not be a complete list)

  • Toggled BIOS storage mode from AHCI -> IDE and back
  • Removed all non-Microsoft filter drivers from SYSTEM registry hive
  • Installed the storage/chipset drivers for my new machine on the OS
  • Ran sysprep in an attempt to force driver rediscovery
  • Ran a VBS script called Fix_HDC in order to fix HDD controller registry entries
  • Rebuilt the Boot Configuration Data table
  • Rebuilt the MBR
  • Toggled BIOS INT 19 trap delay timings
  • Ran chkdisk and sfc
  • Attempted system restore from the recovery medium
  • Other desperate miscellaneous fixes

Since it always seems to work just fine whenever I place it back in my old machine I'm extremely hesitant to think that it's an SSD or Virus problem... I would really prefer not to reinstall, but rather find a solution that keeps my full copy of Win7 intact.

To make matters worse, boot logging doesn't seem to work at all either.

Any ideas?

Here's the BSOD: enter image description here

  • Check CSM (compatibility support module) in your motherboard setup. Try to enable it. It may be UEFI/MBR issue. Check "Secure Boot" as well. Make sure you have "Other OS", not "UEFI" there. – user996142 May 21 '15 at 2:28
  • @user996142 I just checked and CSM is enabled, and "OS Type" Is set to "Other OS (Non-UEFI)", the same as my old BIOS settings... – joshumax May 21 '15 at 2:30
  • On new system , disk may have different number (not the one written in bcd). hence boot manager does not see it. Have you tried to boot from CD to recovery mode and call bootrec /RebuildBcd ? It should rebuild bcd, and may help. support.microsoft.com/en-us/kb/927392 – user996142 May 21 '15 at 2:40
  • @user996142 Tried that too and it still doesn't boot correctly... – joshumax May 21 '15 at 2:43
  • Try to do bare metal image backup on old hardware and restore in new. youtube.com/watch?v=C3W1edVI5d4 . Do you have external HDD large enough to keep backup image? – user996142 May 21 '15 at 17:56

You are probably missing a device driver, I would guess the one for the motherboard.

Try to repair Windows as described in How to Run a Startup Repair in Windows 7. This mode of soft installation will scan your Windows 7 computer for a startup problem and try to fix it so your computer can start correctly, especially in your case fixing missing or damaged system and driver files.

If this doesn't work, get the driver from the ASUS website and add it in during the above installation process.

  • I've already installed both the chipset and storage drivers from ASUS' website... Sadly this did not fix it either. – joshumax May 24 '15 at 7:01
  • Did you try a Repair installation? – harrymc May 24 '15 at 12:57
  • Yes, I tried this on the old, working computer but when I went to transfer it into the new computer it still didn't boot... – joshumax May 24 '15 at 17:56
  • You have to try it on the new computer, since it has to detect the right hardware. – harrymc May 24 '15 at 18:03
  • How would I go about running a repair installation that preserves my data when I am unable to boot Windows 7 on the new machine to launch the executable? The bootable repair disc works, but IIRC if you do a repair from there it doesn't preserve your data/registry. – joshumax May 24 '15 at 18:07

With Windows 7, I've never had a problem inserting a drive into another computer. Even from desktop to laptop and vice-versa has worked numerous times.

I really want you to try installing a fresh copy of anything (preferably vista or 7) to check if there might be other hardware problems. If if fails to boot a fresh install on a clean disk, there are obviously other issues at hand.

Please also try booting with only 1 memory stick inserted into the mobo. Insert it in the first slot in the first channel or as described in the manual. I have built too many x79 and x99 machines to skip this step. The mobos are very fragile in my experience.

Make sure the SATA-mode is the same as in the old machine (probably AHCI).

and finally; did you make sure to uninstall Intel Rapid Storage Manager and all other Intel storage-stuff and Intel Matrix and such on the old computer? If the storage chips are very different, and the wrong drivers are loaded pre-winload, the 0x7b BS will definitely show up. Don't install any new storage drivers, just remove all storage-related drivers and clean the registry for on the old computer and shut down (don't restart). Move your hdd to the new machine and "complete the reboot" there (turn it on).

    Perhaps I have seen to many bad question in a short amount of time. This answer just seems to list a bunch of stuff that might solve the problem, most of these things, and on top of that are clearly things the author already tried. This is more then a bad memory module problem. – Ramhound May 27 '15 at 15:31
