Well, if you're using Mandrake 8.0 (which is awesome by the way), just boot from the Mandrake cd and start the install. It'll ask you how to partition your drive with an easy graphical interface (you'll see what I mean). Here's how I do it:
1. Make a 10 gig FAT32 partition at the start of the drive. This will be C:\ for windows and programs. It'll be the fastest part of the hard drive.
2. Make a 5 gig FAT32 (yes FAT32, trust me. you'll switch it to ext2 later) partiton next. This will be your / in linux and is where you should install linux. You won't need that much space as the linux install is a max 2 gigs, but linux can read/write to DOS partitons so you can keep any linux downloads/rpms/whatever in your DOS partitons and then move them to your linux partition as necessary.
3. Make a 250 meg FAT32 partition after that which will be reformatted to your linux swap partition later.
4. Use up the rest of the drive as a FAT32 partiton. This will be D:\ and you should keep any mp3s/movies/downloads/other data files here. This is just in case you mess up windows and have to reinstall it. This way you won't lose all your data for a windows reinstall.
5. Finalize these settings, and ignore any messages saying you don't have an ext2 partition. Let the partition table be written and then exit the install right there.
6. Reboot with the windows cd. Install windows to C:\
7. Reboot with the linux cd. When the partiton utility comes up again, reformat the 5 gig partiton to ext2, and the 250 meg partiton to swap. Continue to install linux.
You should now have something like this:
---C:\(fat32)---|--/(ext2)--|-swap-|------------D:\(fat32)----------|
That's probably the easiest way to do it.
Good luck.
