You would want to convert an MBR basic disk to a GPT basic disk in the following cases:
If you need to convert a basic MBR disk to basic GPT:
You will receive a warning window, stating that you are about to convert MBR into GPT.
(To finish the added operation you will have to commit it. Exiting the program without committing the pending operations will effectively cancel them.)
Please note: A GPT-partitioned disk reserves the space in the end of the partitioned area necessary for the backup area, which stores copies of the GPT header and the partition table. If the disk is full and the volume size cannot be automatically decreased, the conversion operation of the MBR disk to GPT will fail.
The operation is irreversible. If you have a primary volume, belonging to an MBR disk, and convert the disk first to GPT and then back to MBR, the volume will be logical and will not be able to be used as a system volume.
If you plan to install an OS that does not support GPT disks, the reverse conversion of the disk to MBR is also possible through the same menu items the name of the operation will be listed as Convert to MBR.
Dynamic disk conversion: MBR to GPT
Acronis Disk Director Lite does not support direct MBR to GPT conversion for dynamic disks. However you can perform the following conversions to reach the goal using the program:
