Rakin, okay, let me understand what you have and what you want.
You have WinME in your computer only, at this moment.
What you want, is WinME and Mandy. on the same hardrive.
If you don't want to go and buy Mandy at your closes computer shop, then yes, you can download it from their site. It'll take you a while...specially if you are on dialup...but it's doable. Then you just burn the image onto a CD.
Then reboot your copmuter...go to the Bios and select...
Boot from CD.
save and exit.
put your new Mandy cd in the drive...and it shall boot from the cd with the Many installation.
afterthat follow the installation instructions....I'm not sure exactly what follows because I've never installed Mandy...I'm a Redhat guy. And recommend you to try redhat, actually, instead of Mandy,
Anyway...you should get, in the mandy installation, to the point where you need to partition your hardrive. I hope that Mandy comes with DiskDruid. It's a very nice program that can be used to partition your hardrive.
So use it to make it to split the Windows parititon and then make the partitions for Linux...which are /boot, /, and /swap
then say yes to formating those three partitions. Make sure you didn't select, partition the Windows partition.
Also...BEFORE...you do any of this..you need to defragment your Windows ME hardrive...so leave it over night...or when you are going to the bar to pick up some girls, hehehe
After the hardrive is defragmented you just follow everything I told you...this is so that all the data is moved to the front of the hardrive and so that Disk druid can partition without problems of having Windows data in the Linux partition,
