in signature the specs appear clearly. On my standard BIOS version, it displays an EFI Shell prompt with various messages during startup. Switching to the latest BIOS (my motherboard supports dual BIOS) takes me straight to the BIOS menu. The drive appears in the attached drives list but fails to boot. I typically have three drives on my desktop managed by a Kingwin SATA power switch in front of the case: one for work, one for gaming, and a third as storage—all SSDs. The switcher lets me select which drive to boot without having others powered on, so I don’t have to choose in BIOS. When I boot into the game drive and connect my work and storage drives, everything works smoothly. I can even access files from my work drive. It seems the drive isn’t broken. Notably, when I open Windows Partition Manager, the booted drive (game drive) shows only a 100MB EFI partition labeled “Basic Data” with no Boot or Page file entries—just as the non-booting drive does. This discrepancy raises a question: could this missing information be causing the boot issue? Is there a way to resolve this without reformatting? I’m relieved I can still access files externally, but I really need to boot into this drive to deactivate licenses or reinstall Windows.
