Using VeraCrypt 1.19 (64-bit)
Initially the SYSTEM_DRV was on DISK 0, which is an older slower disk. So I copied the partitions to my DISK 2 SSD Drive which has windows installed, removed the DISK 0 drive, restarted and then put the DISK 0 back in again. Checking in AOMEI shows everything
to be correctly now.
However when I try to encrypt my system drive now I get the following error:
I somehow suspect system drive encryption only working for DISK 0 and isn't working in my case since the Windows installation is on DISK 2.
Now I have tried to remove DISK 0 completely and have my SSD in DISK 1 but it still shows the same error.
