Well, then I had tried with a XP-cd, but still, it won't boot??
Why can't I boot from a CD/DVD???

please help... thank you...

*I have my BIOS-setup right - CD/DVD as 1st boot, hardd. as 2nd.
**Sorry for my english...

you have to install xp before ubuntu and dual booting with vista often causes several problmems also when it comes to partitioning i reccommended making a live cd of gparted.

Did you make a partition formatted ntfs to install Vista?

Firts I made 250 gb space on the arddisk without any partion, and made my partion with ubuntu to 50 60 gb, but it didn't work.
Then I tried to make the 250 gb free space to ntfs, and I could see the partion in ubuntu beside my ubuntu partion on 60 gb, but still it won't boot from the CD/DVD.
Do I really have to install windows before ubuntu?.. I don't want to reinstall my ubuntu :(

No you don't. What will happen is that you can only boot into XP. To install GRUB again, I would use Super GRUB Boot Disk (http://www.supergrubdisk.org/).

OK, also what I understandet from the tutorial I followed...
So now the problem still is: why can't I boot from a windows CD/DVD?, but it works fine with the ubuntu live-cd... :S

For some reson, my computer didn't want to boot vista-dvd...
But I gut it to install xp from the xp-cd...
Thanks for help :D
