I have a 4TB SSHD that was originally partitioned with an MBR instead of a GPT (my motherboard was not EFI capable at the time).

I want to convert my drive to a GPT to make the full 4TB available to me under the following circumstances:

No data loss
My C: drive is still bootable

According to AOMEI and Disk Manager, I have the following partitions, in order:

*: System Reserved (350 MB)
C: Boot Drive (250 GB)
*: N/A (450 MB)
G: Game (A partition I made. 1.76 TB)
Unallocated: 1.64 TB

I am on Windows 10 Pro 64-bit

Will using gptgen to write a new partition table to my disk infringe any of those circumstances? Is there a better way?
 
Solution
you should be able to use gptgen to convert it without losing your data. There are also a lot of free Partition programs that can convert it without data lose.


EITHER WAY BACKUP YOUR DATA!!!
