Find the drive here, right click Change Drive Letter and Paths, the
Make Partition Active. The boot disk will have a status of Healthy
(System).
You can't change the letter assigned to the operating system.
Bill, what you have to do when you clone a drive to replace C: drive is,
after the operation is complete and Windows has re-booted, go into Disk
management as described above and remove the drive letter for the partition
that's going to be the new C: (You can still do this if you have the old
drive intact with data, change than back again for a few minutes).
If you do that, on booting with the new drive Windows will automatically
call if C:, if, however, it's already been in a Windows system and assigned
a letter, it will keep that letter. (And C: will become available and
assigned to whatever drive is next added).
I've struck this myself as I have half-a-dozen PCs and, when I get a new
drive for one, invariably the removed drive goes down the food chain (so to
speak) so a lot of cloning is required. You always have to remove the drive
letter from the new bootable partition before removing the old one.
Good luck, I hope you haven't wiped your old drive yet or you'll have to
live with the new arrangement unless you re-install from scratch.
