ouch - sorry to hear that, Jack
i didn't know you could get win7-64 for $70, though
still, before i spent the bucks, i'd verify the hidden partition is really gone
if you re-partitioned the drive, it may be gone, as you say
if you re-formatted, it may not be
you can examine the partitions by using the admin tools, computer management, disk management snap-in
if you have a small partition (something less than 15 gb, i would think) that isn't otherwise visible, it may still be there
Vortex has the right idea
if you can get a copy - your OEM license should still be good and valid :t
another way to see if the partition is available....
try the F11 key several times while re-booting :P
