My humanity to others (ubuntu) remains

So I tried getting rid of my Linux (Ubuntu for those who are interested in my favoured distribution) partition, but failed. This is mainly due to my ineptitude at reconfiguring my partitions. Basically I tried to just delete the Linux partition and then expand my existing Windows (NTFS) partition into the free space - QTparted (which I was running from a Knoppix CD) didn't want to do this. Also because my GRUB loader now couldn't find the Linux partition (which I had managed to delete) it just decided to throw up an error and stop, so I couldn't even access Windows. Now I'm sure there are ways to get to your Master Boot Record and change things around there to make everything work again, but I don't know how to do this, so what I had to do was reinstall Linux (this time on a much smaller partition) so that I could reinstall GRUB. I did however manage to leave another 20Gb partition which I formatted as FAT32 so it can be accessed with read and write in both Windows and Linux - this should give me enough space to play with. So I still have Linux, which is good, and I now have more disk space to access from Windows - things didn't turn out too bad and I've not had to reformat the entire drive or anything.
