[SOLVED] Change default OS in Ubuntu bootloader

[martinfromdublin]

On this particular machine I'm running Ubuntu 10.04 & Open SuSe from the first hard drive & LinuxMint 9 plus Mandriva 2010 on the second drive. I've found out from posting elsewhere on this site that the Ubuntu family & Suse use different versions of GRUB so one may not boot the other. Ubuntu's boots itself, Mint 9 & Suse but not Mandriva, Mandriva's boots itself & Suse, Suse returns the same favour. So my work-around has been to install the Mandriva bootloader onto a floppy & Ubuntu's onto the MBR.

Now, the issue is I want Mint 9 to be the default but when I try to edit the menu/ist file using gedit all I get is a blank page, no data.

Any suggestions?

Ubuntu 10.04/Mint 9 use GRUB2, which no longer uses /boot/grub/menu.lst for configuration.

You need to edit /etc/default/grub and then run sudo update-grub

Thanks a million for that! It took a bit of trial & error but I got it right in the end
