I was trying to convert my MBR disk to GPT disk using MBR2GPT. I first checked the partition list using DiskPart, and I saw there were 4 partitions:
DISKPART>list partition
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 49 GB 31 KB
Partition 0 Extended 415 GB 50 GB
Partition 3 Logical 200 GB 50 GB
Partition 4 Logical 215 GB 250 GB
I checked the extended partition:
DISKPART>detail partition
Partition 0
Type : 0F
Hidden: No
Active: No
Offset in Bytes: 53801556480
There is no volume associated with this partition.
I tried to delete it but it encountered the following error:
DISKPART> delete partition
Virtual Disk Service error:
The extended partition is not empty.
I tried to format it, but it seems I can't format the extended partition.
