Ubuntu
grub2 package

I have Ubuntu10.04 installed on a 40 Gb secondary drive and 11.04 on my 80 gb main drive, but when I reboot it starts up in 10.04 LTS without showing the boot up menu allowing me to select which system I want to use for the bootup, what's happened?

Asked by Gerard Derksen

I find when I restart my pc(running on Ubuntu11.04 on the main 80 GB drive, with version 10.04 installed on the 40 GB secondary drive, that the reboot screen doesn't get to the stage where I can pick which version I would like to boot from, but instead, after taking a really long time to complete the boot-up"longer than five minutes" it boots into the Ubuntu 10.04 screen, How can I get it to boot into the 11.04 system using the 80 GB drive?
As you can tell I am a novice user, can you please help me?

Check the BIOS to see from which drive (the 80s or 40s?) are you booting from.

Boot then open a terminal (Ctrl+T).
Run commands:
   sudo apt-get install os-prober
   sudo os-prober
   sudo update-grub
and reboot. The other distro should be detected. Check in /boot/grub/grug.cfg that you have both distros.

Another possibility is that the menu contains both distro: 10.04 and 11.04, but is not displayed.
In this case, edit file /etc/default/grub.d and remove '#' before line defining resolution, then run "sudo update-grub" and reboot.

Thank you katzerisko, your answer has completely helped me to get a bit more understanding, as it booting from the

40 Gb drive and when I changed the BIOSto boot up from the 80 Gb drive, I found that (once AGAIN) I have lost the

11.04 installation, I don't know if this is some sort of bug in 11.04 or not, but every time I install it on my pc, I end

up losing it from my system plus anything I had in my browsers or files. Thanks again

Re the advice from De-lance, where exactly would I find grug,cfg? I've looked in the /boot/grub files but there is no evidence of any file named grug or grug.cfg

I've lost the reply from katzerisko (pre11/06/2011) But being a complete novice where in the BIOS do I find the boot order for the 80Gb and the 40Gb drives with the 40Gb drive being the Primary Master Drive

Depends of your BIOS software. Google to find user manual.
