Losing partitions after every reboot
- by Winston Smith
I have an Acer laptop with one hard disk, which up until yesterday had 4 partitions:
Recovery Partition (13GB)
C: (140GB)
D: (130GB)
OEM Partition (10GB)
I read that the OEM partition has all the stuff needed to restore the laptop to the factory settings, but since I'd already created restore disks and I needed the space, I wanted to get rid of it.
Yesterday, I used diskpart to do that. In diskpart, I selected the OEM partition and issued the delete partition override command which removed it. Then I extended the D: partition into the unused space using windows disk management.
Everything worked fine, until I rebooted my laptop, at which point the D: drive vanished. Looking in windows disk management again, I can see that there's an OEM partition of 140GB, which is obviously my D: drive.
So I used EASEUS Partition Master and assigned a drive letter to the 'OEM' partition and I was able to access my files again. However, every time I reboot, it reverts back.
How do I fix this permanently?
