Blech. Updated the BIOS as prompted and now the BIOS doesn’t detect the Linux SSD. 🙁 Off to support I guess
Edit: Will need to dig up a USB drive first that I can use. Should have one somewhere…
The boot menu was working correctly up until the firmware upgrader removed its own entry from the boot menu so in doing so, it somehow corrupted the EFI image on that drive. Shouldn’t be too difficult to fix, methinks. I’ll just need to get the steps from support after I create a recovery USB drive to perform the steps. And, of course, I’ll need to report the bug to them 🙂
