Start OS refuses to start, says "_main already exists. "

I moved so my mini PC was off for a month. My other mini PC was off for a month but it boot up and synced with the BTC network.

The error "Disk management error.

Device EMBASSY_3J6XIWMTJJ554KRFEYPOVMBAIDBKOWTTNDY6ZVERMWHJ6M3DWXNQ_main already exists. "

I have restarted my mini PC, did a system rebuild, and I “repaired” the drive.

Nothing helps.

It would appear there’s some kind of issue with the logical volumes, specifically the one for the OS, or worse, with the physical disk or the partitions.

You should go through the reflashing process and reinstall StartOS, choosing to keep the existing data when asked.
