For some reason the fat partition on my c: drive has
become drive G:, & I would like to restore it as a
partition on drive c:
This is a bit unclear. A partition is a section of a given physical
drive, and C: would be a partition, not a physical drive, so you may
have a g: on the same drive as your c: is, but can't have a g 'on' the
c;
IF (and only if) what has happened is that the partition with Windows in
it used to be C and is suddenly G without your doing anything, then it
is possible to change that back, but not through disk management. And
only for that case - if it has become G after a reformat and new setup
you are stuck unless you go back and start over, reformatting and
removing the cause (eg a Zip drive getting its nose in).
But - in that case only - Start - Run - regedit.exe, open the left pane
to
HKEY_LOCAL_MACHINE\System\MountedDevices
and look in the right pane for
DosDevices\G:
Double click that and very carefully change the G: to C: (start with a
left arrow so you do not rub out the whole thing). If there is already
a \C: entry change that one to have some unused letter first.
Shut regedit and close/restart
