Grub dual boot issues
Hi, I have an old PC here at work with 2 disks. Not wanting to nuke my windows data disks I've partitioned the second disk and installed Ubuntu on /hdb6 as / and /hdb7 as /home. Unfortunately when I came to reboot GRUB has failed. Does anybody know a work around/fix to this? I previously had the same problem with Fedora and ended up using Suse and booting via the CD. Now I want to move to Ubuntu because it is better and should support my webcam (I want to use the PC for the access grid). Any help would be appreciated Simon

Simon, there are two ways around this. One is to get grub onto drive A, as it seems like it put the loader onto drive B. 1) change the BIOS to boot off drive B for Linux, returning it to drive A for M$ 2) boot from the CD (or try the above) and re-install GRUB onto drive A. NOTE: sometimes *nix swaps the drives ie HDB becomes HAD and visa versa. I noted no swap partition on there either. HTH Keith

Hi Keith, Thanks for the tips. I'll give them a try. As an alternative, is there a way to boot from a floppy or CD like in the olden days?! (as I'm fed up with having to reach for the windows installation to run fixmbr and fixboot) BTW, there is a swap partition, I just failed to mention it. Simon

Simon Hi Simon Thats fine, nice swap partition ;) There is a way to boot it, but I dont have the ALL the info but from the grub command line its a bit like... boot linux kernel=vmlinuz root=/dev/sdb6 You do not need to tell it about the /home as that is in the /etc/[v]fstab on sdb6. Also the kernel needs to the same/similar. HTH Keith
