Windows 7: Windows 7 Boot messed up after CMOS reset

Windows 7 Boot messed up after CMOS reset

Hi Guys,

I need some help. Yesterday when trying to revive my computer from putting it to sleep the night before, it wouldnt display anything on screen and after forcing a shutdown manually, it was stuck on a bootloop before POST, and so I removed and reseated the GPU and the CMOS battery which I'd seen as a possible fix. This fixed the bootloop, but now it wouldnt boot into either Windows 7 or Server 2012 (On separate drives), which i later found out was because the reset reverted the BIOS into IDE mode instead of AHCI. But by that point I had messed around with the Windows 7 BCD so now it only gets as far as the windows boot animation before restarting. How can I fix this?

I have disconnected all other drives except the C drive, and 2 USBs, one containing the Windows 7 Repair disk, the other containing Hirens Boot CD. I've tried using system repair upto 3 times, still wont work.

One thing I have noticed, during the system repair, after the 2nd attempt looking through the details of the repair, it stated that there was no issue and the OS booted successfully stating "Boot status indicated that the OS booted successfully", however on the 3rd try, it brought up some fix on system integrity:

Root cause found:
Unspecified changes to system configuration might have caused the problem

Repair action: System files integrity check and repair
Result: Failed. Error code = 0x490
Time Taken = 67938 ms

Could this be part of the issue?

Any help appreciated, thanks :)

Kenny mate first up not a good move with the CMOS better get it back to the original settings you had in place.

Now can you then try booting with only the C: drive connected - no USB's and into safe mode?

Event Viewer Category For CMOS/BIOS Reset
If there is an Event Viewer category that records each time I reset my CMOS settings in my BIOS setup as I log in, I don't know what to call it. Perhaps it makes no sense to look for it as a Windows event since it happens before the operating system is loaded. I'm troubleshooting and I'd like to...
