I am trying to install Ubuntu 10.04 on my machine which already has Windows Vista and Fedora installed.
I use GRUB to get the boot menu. The GRUB screen looks something like this (has a fedora logo at the bottom)
The problem is that when I insert the CD and try to boot, it takes me directly to the GRUB menu for Fedora/Vista, nothing for Ubuntu.
So, I tried Ubuntu's CD boot helper to help me boot from the CD, and I get this error
The BIOS says that I should press F2 for setup and F12 for boot options. I tried them. Nothing happens except that it goes straight to the GRUB menu.
What should I do?
