Provide more details please..
Boot up to the liveDVD as root(username and password is root) and paste the content of /boot/grub/menu.lst on your Sabayon file system..
Then paste

Code: Select all

fdisk -l

You can also update Grub..

3) slightly more complicated -->
3a. Pop in the Live CD, boot from it until you reach the desktop.
3b. Open a terminal window or switch to a tty.
3c. Type "grub"
3d. Type "find /boot/grub/stage1". You'll get a response like "(hd0)" or in my case "(hd0,2)". Use whatever your computer spits out for the following line
3e. Type "root (hd0,2)", or whatever your harddisk + boot partition numbers are (my /boot is at /dev/sda7, which translates to hd0,6 for grub).
3f. Type "setup (hd0)", ot whatever your harddisk nr is.
3g. Quit grub by typing "quit".
3h. Reboot.
