#13054 closed bug (no change required)

Uninitialized GPT, but no MBR partitions detected

Reported by: Yowane_Haku Owned by: nobody
Priority: high Milestone: Unscheduled
Component: Partitioning Systems Version: R1/Development
Keywords: MBR, GPT, DriveSetup Cc:
Blocked By: Blocking:
Platform: x86


I had an MBR disk (Windows 10) with GPT leftovers. Haiku recognized it as a GPT disk and I thought that initializing it as MBR will only remove the GPT headers. But now the disk is shown empty as if it would be completely formatted. Is there now any way to restore my partitions or was I stupid enough to erase all my data?

Resolution: no change required
Status: newclosed

The first 3 and 2 last sectors of the disk were erased, so the data should still be there for the most part. You will need to find the start sector of each of your partitions and create the matching MBR entries manually.

You can use tools such as TestDisk ( to help with this.

I'm closing the ticket because this is not a bug and there is already a warning that data will be lost. Please use the forum instead for such support requests.

Thank you for help. I was able to fix it. Sorry for troubling you with this meaningless ticket. I understand that this was not the right place to write. And I will try not to get influenced by panic next time =)
