This option has been disabled for system disks or partitions on system disks
This article applies to:
- Acronis Disk Director 11 Home
- Acronis Disk Director 11 Advanced
There is no option to convert to GPT for a disk which contains active operating systems on some of the partitions (usually this is a system disk):
This limitation is due to that a GPT disk can boot on Extensible Firmware Interface (EFI) based systems while Acronis Disk Director 11 does not support systems with EFI and therefore the convert to GPT operation on a system disk will cause the system to be unbootable.
