Apply button is always greyed out

Hello guys, 

I want to clone my C drive to a newer drive...

It's pretty easy, selected C the selected new drive F (attached as external USB drive via usb dock)

But "Apply" is disabled... any ideas what I can do/why that is?

See my Disk 1 (system drive) has three other little spaces before the C: part... could that be causing the problem, and are those bits necessary, can I wipe them without destroying my system?





  • As I know, you should delete the partition on the destination disk and initialize it to GPT style. After that you can clone to it. For the other three partitions, you'd better not delete them. It is a UEFI based disk configuration, you can't delete EFI partition at least, because that partition is used to boot GPT system.
