Before the crash I had a Ubuntu 22.04 and Windows 10 dual boot on the same SSDSCKKW480H6 Intel 480GB hard drive.
I intended to make a Windows bootable recovery image and then wipe everything and go single boot Ubuntu, however I had some Windows updates, saw I could upgrade to Windows 11, and tried that. During the Windows 11 download/upgrade, I got a blue screen error and the computer rebooted, except I got a no bootable device found error message.
I would be happy losing all of the data on both Windows and Linux partitions as long as I could get the use of my SSD back.
The BIOS menu, or at least the only menu I can access by mashing F1 through F12 keys is a setup GUI where I can tweak the boot order and the clock speed, however the actual SSD does not show up as anything to boot from.
I booted from a live USB, and tried Boot-Repair (the suggested repair is "the default repair of the Boot-Repair utility would not act on the boot), however the Boot-Repair text file does indicate that Windows is installed in the MBR of /dev/sdc.

Again, an easy 'wipe everything' command would be a terrific solution at this point although if there is a way of accessing a few recent files on the Linux partition and/or retrieving my Windows license information so I could install Windows again if I needed to, that would be great too.
I do think the root cause if I had to guess is that the Microsoft partition was not GPT which turns out is a requirement for Windows 11, but that's beside the point now.
