I'm trying to use
DiskPart to create two partitions on my flash drive. One for storage and one for a bootable OS. I've used BootIt as suggested in this question/answer, however it doesn't seem to help one way or the other. Perhaps it's out of date for Windows 7, the OS I'm working on, and yes I tried running BootIt in compatibility mode with admin privileges.
Disk Management I wasn't able to do anything but format the current partition, change drive letter, and change drive label.
I then used
DiskPart, which seems to be the best option, to create the first partition. I can see the unallocated space available in
Disk Management after doing this, but when I try to create another partition I get an error.
extended and got the same error message as above. Retried from scratch using
offset and received a different error.
