Well, so much for it being easy.
It's still simple, but it ain't easy.
Here's what's up with the gaming box so far:
Using a second SATA-drive PC'a regedit32 to load the old drive's registry hive and editing it didn't work. When I put the old drive back in the original chassis, same problem.
As if the changes didn't take.
Ok. Round two.
Bring in a second SATA drive and install it on the gaming box.
Then copy the partitions off, loading them onto the 2nd disk.
Then copy them back to the original disk.
During one of these copies, retarget the partitions to the proper drive letters.
I got as far as the 2nd drive installation tonight.
Then I found I didn't have a 2nd power cable to the SATA drive in the packaging for the drive. Had the data cable, but no power. Actually it's not the cable, but the adapter/converter. Little two-inch thing that connects to the power supply line at one end and the back of the HDD at the other.
I have to find a partitioning utility, too. Not going anywhere near Partition Magic again.
The laptop's HDD is completely gone. Have to put a new one in there.
Another job, another day. First is to get the gaming box back up.
Jill is going WOW-nutz. Hasn't played since the system blew up.
