default=0
" setting in "/etc/default/grub
" to "default=4
", then running "update-grub
". This basically tells GRUB to use menu-entry number 5 (0, 1, 2, 3, 4) as the default boot option. Since Ubuntu by default have 2 Linux kernels (regular and recovery) as well as 2 Memtest, this would select Windows 7.A little while later I upgraded several applications in Ubuntu as well as the kernel. Updating the kernel added 2 extra menu-entries to GRUB, which t hen meant that menu-entry 5 ("
default=4
") would be one of the 2 Memtest entries. This would mean I actually had to update GRUB manually every time I upgraded kernels? Nah, I didn't want that. The way I did this was rather simple.First I ensured that the "
default
" setting in "/etc/grub/default
" were set to "0
" ("default=0
") which is first menu-entry. Second I renamed "/etc/grub.d/30_os-loader
" to "/etc/grub.d/09_os-loader
". If you notice there are several numbered files in "/etc/grub.d
". These determines the order of selection (or rather order of compilation) when running the "update-grub
" command. By putting the "os-loader
" entry below the "linux
" entry it puts Windows 7 before the Linux entries in the GRUB menu.
