Bad System Config Info - unable to fix via RebuildBCD
Recently, I was browsing YouTube on my desktop when all of a sudden the power went out - causing a hard shut down. Upon turning it on, it seemed to load longer than usual, before throwing a BSOD with Bad_System_Config_Info. Restarting it, a different one came asking for recovery media to be use for troubleshooting. As I looked through online guides, it seems that, somehow, the Boot Configuration Data was corrupted, and I am unable to "access devices" as the second blue screen indicated.
Using my recovery USB, I checked all volumes were assigned correct letters then tried using bootrec /scanos to ensure the BCD was still there, and /rebuildbcd finding it remained. Despite using the command, it brought the error "The requested system device cannot be found". Further reading has shown Windows RE not functioning fully in certain USB ports, yet switching from USB 3 to 2 somehow corrupted the recovery USB and wouldn't let it boot - prompting me to reinstall the media on it.
I'm still experimenting with other ports, sticking with USB 3 in case 2.0 ports actually affect the BCD on the recovery USB. If it fails, I'll try the 2.0 ports.
If the worst is expected and I have to reinstall Windows, I can resort to that, but that's at the detriment of having to reinstall everything even if they're on other drives.
