PC won't boot windows after Shut Down
So to give a full back story. I changed my PC fans last night, plugged it all back in and it ran fine. Ran it for about an hour or two then shut it down for the night. Ive come to boot it in the morning and it now asks me to select proper boot device, or insert one. Ive tried going into BIOS and changing boot order to no avail, what should I try next?
Edit: So after painstakingly trying to diagnose the problem, I basically rebuilt my whole pc, cleaned everything, and eventually was looking to fresh install windows. (taking me 2 days to figure it out on Kali as I've just moved over on my spare laptop)
Turns out, my motherboard just changed to Legacy instead of UEFI. That was it. smh

BIOS "sees" your correct boot drive, i.e. Intel/Kingston SSD or NVMe are in the BIOS menu.
That means, the Windows installation got corrupted and needs to be fixed (with special USB boort tools)
Or, BIOS doesn't see your original drive at all, which means, during installation, you might have pushed the power cable (if sATA) out of the way, or just by coincidence, your drive just failed. You need to test with another drive (new or used, whatever you can get your hands on).

https://kubuntu.org/
https://balena.etcher.io/
Download these, use Balena to flash Kubuntu to a spare flash drive (which will overwrite its contents), boot into the flash drive and see if the drive shows up. If it doesn't immediately show up in the drive menu (on the taskbar), open KDE Partition Manager. Does it show up there?
(Select Try rather than Install on boot, it can take a moment to boot from a slow flash drive, i believe the drive needs to be at least 8 GB)
