Error message indicates the system drive isn't found during boot sequence.
I need to operate several OSes on my PC, so I recently cleaned up an old SSD and set up Pop!OS there. Unfortunately, the drive isn’t listed in the BIOS boot order even though it’s detected. I can’t reformat it anymore because Windows no longer recognizes it, and I’m unsure how to do this through BIOS. To install Pop! (20.04 on NVIDIA) I used balenaEtcher to flash the drive from a file. Etcher still sees the drive, so it seems functional. What might be causing the drive not to appear as a bootable device? If needed, here are my details: AMD Ryzen 7 5800X MSI B550 A-Pro 16GB G.Skill Trident Z Neo (CL16, clocked at 3600), GTX 1060 6GB SSD — a 2.5-inch SATA drive with 128GB.
