You can use any partitioning app you like. Just partition the disk and run knoppix-installer.

On the other hand qtparted is not that difficult. Anyway, I prefer the simple fdisk. I don't know QuandA, but it is possibly still on the knoppix CD. Have you tried to run it?

If you don't need to resize a partition I can give you a short explanation how to partition your disk with fdisk (for resizing partitions you'll need qtparted - but backup your data before resizing partitions).

Type 'fdisk /dev/hda' (assuming your harddisk is primary master).
Now 'p' prints the partition table.
'n' creates a new partition, fdisk will ask you two questions - start cylinder (which is probably the first unallocated) and size (just type '+1234M' for 1234 MB or '+1G' for 1GB - note that Mega means 1000^2 and Giga 1000^3 Byte here, not the usual 1024^2 and 1024^3).
If you want to create another partition, do it now.
Type 'p' to check if everything is alright
If this is not the case type 'q' this will close fdisk and discard any changes you made. If everything is fine, type 'w' - this will write your changes to the partition table and quit fdisk.
