BSOD on boot - Drive letters switched - Windows on G:
Last night when I went Start menu > Shut down, I got a BSOD. Because it was late and I occasionally get a BSOD without further issues, I just left it.
This morning I find that everytime Windows attempts to boot, it gets just past the startup splash screen, and then another BSOD. "Startup repair cannot repair this computer automatically".
The strangest and I hope most telling and significant part is that the drive letters for my stuff are all switched around. Originally I was set up as:Code:Problem signature: Problem event name: StartupRepairOffline Problem Signature 01: 6.1.7600.16385 Problem Sig 02: 6.1.7600.16385 Problem Sig 03: unknown Prob Sig 04: 21201115 Sig 05: AutoFailover Sig 06: 11 Sig 07: CorruptFile OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033
C:\ - Windows OS
D:\ - System Reserved (I assume)
E:\ - Temp drive partition
F:\ - Data1
G:\ - Data2
Now, it seems that windows has been reassigned to G:
C:\ - Temp
D:\ - System Reserved
E:\ - Data2
F:\ - Data1
G:\ - Windows OS
I have tried to use diskpart to reassign the drive letters back how they were. I was able to do this from the command line, but after rebooting, I get another BSOD and the drive letters revert to this messed up order.
I took a picture of the BSOD code and got:
STOP: 0x000000F4 (0x00...003, 0xFFFFFAB00C0***fuzzy**,0xFFFFF80003779E20) -I think
This page: Troubleshooting Windows STOP Messages led me here: https://support2.microsoft.com/defau...b;en-us;330100 which kind of makes sense if windows is now on a G: drive??
I also tried this: Bootrec.exe Tool - How to Use in Windows Recovery Environment
with no luck, I get "file not found" for bcd.
The Startup Repair also gives these error codes:
I can't run the DM Log Collector because I can't boot into windows (I'm troubleshooting and posting on a macbook).Code:Root cause found: Unknown Bugcheck: Bugcheck f4. Parameters = 0x3, 0xfffffa800be76b10, 0xfffffa800be76df0, 0xfffff800037cce20. Repair action: System files integrity check and repair Result: Failed. Error code = 0x490 Time taken = 266045 ms
I can't think of any recent hardware or software changes, although I did get a system update two nights ago I think.
Thank you so much for any insight. I do have backups and am willing to do a restore or fresh install, but it would be good to know if this is hardware, software, malware, or a freak accident. I also kinda wanted to wait until Win 10 came out before doing a new install. *sigh*
