Wow, thanks for the fast reply!
I didn't have a backup of the image, but I only just finished installing everything, no sensitive content was lost.
However, how would I go about formatting the drive this time, SSH?
And, if nessecarry, because even creating a new VM using the default UnRAID array storage... I can't get a new VM of Windows to run (black screen), how would I do a revert?
Edit:
Or can I do a clean 6.2 b21 install on my USB stick, and keep the Array in-tact /working?
