I want to change the default grub entry to my specified entry. I know specifying the menuentry number can work. But it's too much hard coding and not flexible because when I add more kernel images, the number changes.
So I want to specify the default grub entry by specifying the grub menuentry's name.
My grub menu went through rather extensive changes after the last update. It started booting to my old 12.04 entry by default. Where this gets confusing is that there is no longer a 12.10 entry in grub.cfg.
I installed and tried the grub-cfg as mentioned in How do I change the grub boot order?
I'm trying to configure grub on my computer. I use the dual boot with Windows and Ubuntu. The grub always suggest with a countdown from 10 seconds to boot the Ubuntu. However, I do not want to be that way because other people in my home also use the computer and do not have much affinity with Linux.
I have a dual boot Windows Vista and Ubuntu 11.04 desktop. I wanted the default os to be the last one that I booted so I edited the grub file in /etc/default/grub. I changed the line GRUB_DEFAULT=0 to GRUB_DEFAULT=saved. Then I ran update-grub. I rebooted the machine and now it doesn't display anything. Grub menu doesn't display. Bios doesn't display. Can't boot from a cd.
