Following the step to make my partitions I'm yet again stuck :/
All partitions deleted and new ones created, boot flag and system set
now to complete type 'w' and thats when I get this:Re-reading the partition table failed with error 22: Invalid Argument
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.
okey, no problem, ill just reboot
... not, after rebooting I went back to the fdisk and I couldnt see my new partitions 
(no partitions att all, so I created new ones and same thing happend as I tried to 'w'rite)
how am i suposed to save my partitions?
thnx in advance
Edit*
Found my way to the mIRC and got some help, learned to use cfdisk instead of fdisk. Solved my problem
