boot files were on C: by default and in my case boot.ini is a little different. it works, however system does not boot from any of drives, i put boot files on all of them and still nothing. i guess i should make ubuntu live on usb stick, reset flags on drives, make my main drive C: agan and reinstall.. EDIT: @wimb: that makes things quite clear, well i was thinking about something like that just using linux tools. thx, ill try this out ;] EDIT2: Well i couldnt get it working heh. Finally i got back my dvd-rom, booted up ubuntu, used gparted to delete F:, created new partition, had set it as boot, had unset all flags of other partitions, reinstalled xp from cd and now it works as it should. Sort of victory, not rly heh
