LDM Metadata partition on a dynamic disk: Recognized GUIDsĪny partition type GUID can be specified with this parameter Maybe using the GUID for a Microsoft Reserved Partiton or ?įor GUID partition table (GPT) disks you can specify a I don't want a Basic disk converted to dynamic. Turns out that GUID listed above in the map switch is a GUID for a dynamic partition. It does boot, but Disk Management sees it as invalid and dynamic with no partitions. After using this command, the disk was converted to DYNAMIC, INVALID. Mbr2gpt /convert /disk:0 /map:222= /allowFullOS I used the example given and it worked flawlessly for me.
