Grub Loading

FrostedNipple · 26 Jun 2008 at 10:08

This has only just occurred recently and happens on every boot. When I used to boot, it would do its post, BIOS stuff etc, then straight onto grub loader so I could choose between XP and Ubuntu. However, now when I boot, instead of going straight to the grub, i get a little flashing underscore, then some words about grub, this adds about an extra 10 seconds to loading time, sure its not much, but I'm more worried about why it has just started to do this, as I don't particularly want it getting worse. I loaded up Ubuntu yesterday as I haven't used it for about 4months, wondering if a cache got deleted or something and a boot into Linux would fix it up, however it hasn't. Any ideas on how to sort this?

re-install/re-run grub setup?

when you booted Ubuntu did you update any packages, kernel etc?

nope no updates, no setting within linux have changed, it just decided to take longer to load grub

boot into linux and reinstall grub (not the package!) - should sort it.

Once in grub, if you're not sure of the BIOS order of your disks, use the

grub> geometry (hdX)

command to work out which one you're booting from (X is an integer, starting with 0), once you know what drive you're wanting, you can then use the

grub> root (hdX,Y)

command to set where the grub config files are installed (whatever partition you have /boot on - Y is an integer, also starting with 0)

then install GRUB with

grub> setup (hdX)

to install to the mbr... it usually wants to go on the mbr - but not always, I had one install which wanted to go on the partition: setup (hdX,Y) - wtf?!

MAKE SURE YOU GET THE RIGHT DISK!!

is this still open?

my comments above should be able to help.

From the outputs of the above commands, you should be able to tell exactly what drive is what.
