Sorry, what do you mean by that sentence? Did you partition a single drive
as 7.2GB and 14GB? If so, that has nothing to do with Primary vs. Slave.
I now need more space. Can I switch to the larger HD now?
What options do I have?
Are you running out of space on C:? With a drive as small as 21GB, I think
it's a mistake for most people to have more than a single partition. If I
were in your shoes, I would change to one partition. Reversing to the two
drives is likely to be only a stopgap measure.
Unfortunately, no version of Windows provides any way of changing the
existing partition structure of the drive nondestructively. The only way to
do this is with third-party software. Partition Magic is the best-known such
program, but there are freeware/shareware alternatives. One such program is
BootIt Next Generation. It's shareware, but comes with a free 30-day trial,
so you should be able to do this within that 30 days. I haven't used it
myself (because I've never needed to use *any* such program), but it comes
highly recommended by several other MVPs here.
Whatever software you use, make sure you have a good backup before
beginning. Although there's no reason to expect a problem, things *can* go
wrong.
Moreover, with a total of only 21GB, no matter how its partitioned, it's
likely that you will soon need a larger drive. Fortunately they are very
inexpensive now, so you best solution might simply be to buy a drive of at
least 80GB or so.
