For your mandrake box, do the expert install and when you get to the partitinging screen, just hit clear. It will clear the partitioning table (good idea).
Then hit auto-configure and select the /usr option. Now write down the partition info that it created on paper. You can note the
Name
Size
File System
Mount Point (where it get's mounted in the linux file system)
Consider any other partitions you would like to make such as /var.
Then hit clear again.
Now make each partition by hand. I suggest reiserfs as your linux file system rather than ext2 or 3. It's worked very well and is a journaled file system. Many users are swearing by it. All my linux partitions are reiserfs except the swap partition.
For the first partition / (boot/root), click Preferences and select Primary. For the remaining partitions, click Preferences and select Extended. This will leave you with the ability to make 2 more primaries down the road.
When you are done, you should have something like this..
hda1 - / - reiserfs
hda5 - /swap - swap
hda6 - /usr - reiserfs
hda7 - /home - reiserfs
You can also make additional partitions such as MEDIA or DEV (development), based on your needs.
The goal of making separate partitions is that the file systems will be quicker and also easier to backup. It's easy to backup a 2 gig partition vs a 20 gig partition. Easy to put them on CD's or copy to another hard drive.
Check out www.partimage.org for free ghosting software.
Another option is to put a second hard drive into your win2k computer and install linux on that hard drive. This will allow you to share files easily unless you want to network your computers and use samba to transfer files. If you put them on the same computer, then you should probably make a Fat32 partition for sharing files.
Regarding NTFS, you had the option if you installed from CD. It was the blue screen asking you to format. Win2k is a neat OS compared to the other ones. You will probably like it
I would recommend you redo your NTFS system. I would reinstall Win2k and make it about 2.5 gig in size. Get the system up and running with drivers and anything that doesn't expire (in terms of software such as virus software).
Then use the win2k Disk manager to create a new extended partition that takes up the rest of the drive. Within the extended partition you can make other partitions for various purposes (same ideas as with linux). I have a software partition, media partition, development so on. Never use the a windows disk manager or fdisk to modify a partition table with linux partitions, you will be sorry! Always use a linux disk manager instead.
At this point, use partimage or ghost to burn a copy of your NTFS partition and save it on CD so you can always restore it if it ever gets screwed or you simply want to go back to a clean install. Try to do as many customizations as possible before you burn it. Prefer a list view vs a folder icon view. Set it before burning the ghost.
Once this is done, you can install additional software, everthing you need. If you make a software partition, this will be D:. You can install everything to that.
I also right-clicked on my computer, select properties, advanced, environment variables and moved my temp folders to a different partition (such as D: or what not). This keeps my C: from filling up with junk after a while. Lastely I moved my swap to some other partition besides C:.
