Hmm, ok, we'll put my creative thinking to work.
-Boot with the Mandrake boot disk
-At the command line, type cd /; mkdir {stuff, disc1, disc2, disc3}
-Mount your windows partition using mount -o ro /dev/hda4 /stuff
-Change to the directory the downloaded iso's are in. If they were in C:\Program Files\Stuff,
you would type cd /stuff/Program\ Files/stuff
-Mount the iso's using loopback
mount -o loop,ro disc1 /disc1
-Repeat for disc2, disc3
Replace disc1 with the actual filename
Also, when I say /dev/hda above, replace with the following:
/dev/hda Primary Master
/dev/hdb primary slave
/dev/hdc secondary master
/dev/hdd secondary slave
/dev/hdc4 denotes 4th partition on secondary master
Of course someone probably has a better idea than this convoluted thing. Or if it comes down to it, I'll download, burn and mail them to you.
