Accidentally deleted Acronis drivers in Sys32, need help to boot system.
Hello, I have taken a look at a lot of information. Please excuse any ignorance. In 2019 I migrated to an SSD on Win 7 x64. It went fine. I had Acronis drivers in Sys32, and I had no idea I actually needed these drivers. I was stupid and somehow deleted like 5 drivers from this Sys32 file, and now of course my PC will not boot. I can install the drivers, but I simply do not know how to get them. Right now I just get a bluescreen when booting to safe mode even, and my last restore point will not work.
I can access all or most of my files in the SSD, but I can't boot to Windows. I have no actual back up atm, but I have all my saved files that needed to be saved. I was thinking of just completely reinstalling Windows 7, but I was wondering if someone can point me to any possible drivers that can allow me to boot into Windows. As I said it was whatever Acronis installed into this folder when I migrated. I thought I didn't need them as I had deleted the Acronis software long ago. I see there is a driver page here, but I assumed maybe someone would know more about this. Is there any way I can insert those file back into the sys32 folder to make my Win 7 install boot again?

The BSOD is 0x0000007B, and this happens immediately after it windows logo finishes.

The BSOD is being caused by Upper Filter registry entries still being present after the drivers were deleted. You can edit the registry and remove the entries from a command window in the recovery environment.
Follow these steps:
1. Boot the recovery media and open a command window.
2. Enter regedit.exe.
3. Highlight HKEY_LOCAL_MACHINE on the left.
4. Select from menu File/LoadHive.
5. Navigate to C:\Windows\System32\config. This assumes your Windows system has been assigned C: by WinPE.
6. Select SYSTEM to load the system hive.
7. Enter Remote_SYSTEM to name the hive.
8. Navigate to HKLM\Remote_SYSTEM\ControlSet001\ Control\Class\{4d36e967-e325-11ce-bfc1-08002be10318}
9. Highlight UpperFilters on the right.
10. Select from menu Edit/Modify.
11. Remove fltsrv from the list of Upper Filters and save.
12. Navigate to HKLM\Remote_SYSTEM\ControlSet001\ Control\Class\{71a27cdd-812a-11d0-bec7-08002be2092f}
13. Do the same to remove the fltsrv Upper Filter.
14. Highlight HKEY_LOCAL_MACHINE on the left.
15. Select from menu File/UnloadHive to save the changes.
Windows should now boot properly. Then you can reinstall True Image to get the deleted drivers back. The Upper Filter entries will also return.

Just curious as to why your "restore point" won't work? Do you have a security tool loaded such as Norton? It will sometimes prevent the restore point from working if "tamper protection" is on at boot up!
Cheers and good luck!

Hello, thank you for the solution. I ended up reinstalling Win 7 totally to get off the partition and drivers from Acronis. If I ever need to know again, this thread is helpful. Thanks.
