I made a dual-boot system back in 2006. It is WinXP and Linux. The disk actually shows 3 partitions: C, E, F drives. First question: Is the smallest of the three a swap-drive enabling the dual-boot, or is it a separate drivespace for booting Linux? Now the beef of what I am getting at. I have found that Linux just does not have the driver support needed to have it on my current system, so I want to wipe the Linux partition and reallocate that space back to the WinXP C-drive. I am sure that this is normally a painless proposition using Partition Magic, but what worries me is the extra drive partition (swap-drive?) that I am unsure of its function. I just do not want to wipe the Linux partition and reallocate it, then have boot problems with WinXP because I did not do something else I should have done with the drivespace in question.
P.S. - I am going to a virtual desktop environment for Linux so it can use Win resources where it lacks in driver support.

If you have been using Linux at all, you should know that things like "C, E, and F drives" are meaningless in Linux. Usually when windows user refer to "drives" they are talking about "partitions". It seems from your post that you have one physical hard drive? with three partitions on it? You neglect to mention which distribution of Linux you have. This is significant because some create a separate boot partition at install. Additionally, there are hundreds of different distributions and it would be difficult to give accurate advice with the information you posted.

If you are still able to boot your Linux distribution, log in as root and post the output of "fdisk -l" (lower case Letter L) so we can see your partition information.

Also, how do you boot your system currently? If you are using the Linux Grub bootloader and you delete your Linux partition, you will have to modify your windows bootloader which will likely require an xp installation disk.

I'm hard pressed to imagine hardware from 2006 which does not now have driver support. Have you tried asking in these bulletin boards, or using www.google.com/linux to search for the drivers you need?

The small partition is probably the swap partition. As yancek suggests, run fdisk -l in a terminal. The output will tell you if it's a swap partition.
Swap doesn't have anything to do with enabling dual boot or with system logging. It's there for use in the event that you don't have enough RAM for current tasks. Unused portions of data in RAM can be held in swap to make room for other data in RAM. As RAM becomes available, the data in swap can be brought back to RAM.

Using Partition Magic will be almost painless, but the pain will still be there. Just delete the Linux and swap partitions, expand the windows partition to take up the free space and write the windows filesystem to that space.
BUT, if you are using the grub bootloader to dual boot, you will need a windows installation disk to fix the MBR (Master Boot Record) so that windows will boot. Even a win 98 disk will work for that purpose.
