I noticed one important item missing from all the ways to install Vista from a flash drive.
The huge Corsair that I have was probably going to take over two hours to format so I decided to add the extra parameter “quick” so that it would be reasonable for a quick repair to my current Vista.
Here is what I used and be careful, your disk is a different number.
list disk
select disk 2
clean
create partition primary
select partition 1
active
format fs=fat32 quick
assign
exit
