I'm using Fedora 16. A friend installed a Mac OS X on my laptop and he installed Chameleon. So grub has been gone. Then I asked for help in #fedora. big thanks must go to <DiscordianUK>! He helps me so much and now I can boot normally (although grub entries are not fine).
I boot Fedora from the Grub Shell like:
Code:
linux /boot/vmlinuz-XXXXX quiet root=/dev/sda4
initrd /boot/XXXXXXXXXXXX
boot
After Started /home it outputs

How to fix it?

Thanks!

because I need to work ASAP so I reinstalled the system.
And a suggestion: Anaconda can repair the bootloader. That's very important because some are using a partition format which they don't know (EFI/GPT).
The documentation for EFI/GPT is not as complete as MBR. An auto-repair feature is very important.
