Should the combination of GPT + boot loader found at offset 8KiB really be a blocker here ? I see two cases: - GPT and boot loader overlap (e.g. standard GPT), the primary GPT is invalid, partitioning tools would rewrite it from the backup GPT and overwrite the boot loader. - GPT and boot loader do not overlap (non-standard GPT, e.g. partition entries <= 56 or primary GPT at offset ~1MiB).
So IMO 'eGON.BT0' can safely be deleted in both cases.
