Re: Xen Not Displayed in Boot Menu

GRUB2 includes a boot image that's loadable from GRUB Legacy, so you can try it out without wiping out your existing, working MBR. To set up GRUB2 without actually writing to the MBR, run
grub2-install --grub-setup=/bin/true /dev/sda
If that works, you can go on testing to writing to your MBR. Same steps as above, but don't tell grub to run the dummy setup program /bin/true
Congratulations! You've reached the point of no return! If you can't boot now you will need to run a rescue CD
