After upgrading my Kubuntu version from CD, Grub started to behave strangely: After rebooting the machine it stopped for around 30s on the Phase 1.5 until the operating systems menu showed up. After selecting the operating system, another 30s until startup.
It took me a while to solve it. I followed some of the instructions that are on this post: http://forums.fedoraforum.org/archive/index.php/t-950.html
It’s not Ubuntu related, but Grub is Grub…
Anyhow, after booting and logged in, I opened a Konsole, and did the following:
1) sudo bash <- to get a administrator shell
2) Started up Grub: grub
3) And checked what is my boot disk (just to make sure): find /boot/grub/stage1
4) It looked ok, so I’ve ran: setup (hd0) (That’s a zero)
5) Quit Grub, and rebooted.
