Webuser Forums: Partition Trouble

OK, here goes.

I have a 330GB HD on my computer, which I initially partitioned into two parts - a primary partition of 30 GB and an extended parition of roughly 300 GB. I installed Windows XP Home Edition on the primary partition (the C Drive). The extended parition was then broken up into logical drives - a 4 GB Page File Drive (D Drive), a 166 GB Games Drive (E Drive) and a 100 GB Storage Drive (F Drive). That arrangement has worked fine - up until now.

I just bought a copy of Windows XP Professional Edition. For whatever reason, I was unable to simply upgrade from Home to Professional, so I did a fresh install (or whatever it's called) of Windows XP Professional Edition, thinking that it would uninstall the Home Edition and put the Professional Edition in its place on the C Drive. Instead, it installed Windows XP Home Edition to my D Drive (the 4 GB Page File Drive), so now I have two different versions of Windows XP on my computer on two separate partitions.

I do not really have a problem with this, except that I basically have to reinstall a ton of software into Professional, and I am fairly certain that I am going to need more than 4 GB of space on the drive (in fact, I only have one GB left). I have managed to eliminate the Storage Logical Drive and thus turn it into Free Space (for some reason, I cannot do that with the Games Drive - the drive has nothing in it, but the option to delete the logical drive is greyed out), but I cannot figure out how to merge this free disk space into the D Drive, so that the D Drive has more space. Is there a way to do that?

Also, is there a way to uninstall the Home Edition of Windows XP? It is not causing any harm (except eating up 30 GB of Hard Drive space, since I cannot reformat the System Drive/Primary Partition), but I do not really need it.

Any help would be greatly appreciated!
