http://askubuntu.com – I've been reading a lot the last 2 weeks, but never found a working solution for my dual boot system. Tried boot manager, this solves the automatic time setting. Tried editing grub cfg by hand, nothing. All i want is: [ ] 1 Ubuntu [ ] 2 Ubuntu single user [ ] 3 Memtest [x] 4 Windows XP GRUB should boot entry 4 by default, but neither specifying the number nor the full boot entry does the job. Any clues? (HowTos)
