I have experienced a power outage yesterday and my computer now has issues booting up. Specifically, my motherboard would keep looping through the status codes up to code 32 "CPU PEI Initialization". This has happened before when I updated the bios and what I did to fix it was the following.
- Disconnect power supply and remove CMOS battery.
- Wait 5min.
- Flick the switch on the motherboard to a different bios chip (I have a Gigabyte motherboard with 2 bios chips)
- Reinsert battery and plug in to the power supply again.
- Turn on the computer
- Load bios defaults
After I loaded bios defaults, I had gotten the same error as I have now, "Inaccessible_boot_device". I was lucky that there was a system restore point back then, so all I did was restore it and it was working again. Unfortunately, as luck would have it, system restore currently tells me that it has no system restore points.
I tried everything from rebuilding BCD, using SFC /scannow, and DISM, but it was all to no avail. There is some information online telling me to mess with to mess with the SATA mode in bios. I tried changing it to the different modes, but eventually I just left it on what it was on when it was working (AHCI). I looked up information on Inaccessible_boot_device and this page tells me that there might be some useful information stored in the first parameter of the stop code. Unfortunately however, Windows 8+ BSODs no longer have these hexadecimal numbers. I became interested in trying to get the dump files, but there are none that are generated. Even enabling boot logging in advanced options produces no ntbtlog.txt.
I know I will probably have to end up reinstalling Windows, but I would really prefer if there was a solution that does not entail this since I would have to set up a lot of programs again.
I am hoping that there is some way to manually redo what system restore once did to fix this problem.
