Install hangs at "update-grub"
I am trying to install (k)Ubuntu in a dual boot scenario on my Sony laptop, I have a reasonable amount of experience installing Ubuntu on a variety of machines, but this is the first dual boot.
I have tried Ubuntu 8.10 (from standard desktop install CD) and now Kubuntu 8.10 (from alternate disc to try to text install) but BOTH get all the way to the final stage and then hang with "Running 'update-grub' ... and I finally have to button the machine.
I am trying to install GRUB to /dev/sda3 (ext3) rather than the MBR as I do not want to risk screwing up the XP installation (some of my clients run windows only software). The laptop has a "system rescue" partition as the first on the disk, then the Windows partition, then I created the /dev/sda3 for Ubuntu and in an extended partition, a FAT32 share partition and a Linux sap file. I did a lot of investigation around the net before trying this, backed up by MBR as I managed to trash it while following a set of instructions to install GRUB after the install.
I have to say, this is getting VERY annoying and can only think it is something to do with the rescue partition or some odd Sony hardware issue.
Any insight into why this is happening and a possible fix would be MOST appreciated!
