Dual booting Sabayon and Mac OS X

Postby death_metal_scottie » Fri Oct 05, 2007 18:58

hey so i dl'd a copy of Mac OS X, i have a legit copy ;), ive been trying to configure GRUB to boot to the drive that I installed OSX onto. I can't get it to work. This is my bootloader script. I've never really messed with grub, i always just set which disk gets booted first in bios and boot from there. but heres my grub.conf. The drive that it needs to connect to is a 40 gig harddrive on IDE port 1. I tried hd1,0 but no boot. I exprimented with a few others, no go. help please. also sorry if this is in the wrong topic area!

As far as I know you have to first have osx installed and then using bootcamp make space for linux.
Next install linux into free space and then once trying to reboot = no go only osx then into osx get "rEFIt" and use this as boot menu to boot either osx or linux.

Or this was the last way it worked.
Think the problem is with osx trying to be big boss with boot menu or you have to if linux is 1st and osx into spare space using chainloader+1 first install HFS+ or something file support even though it should pass to the next hd and tehn boot it provided the osx boot is writen to the osx partition and not MBR of hd.

/dev/sd4 instead of /dev/sda. Just search the forums / wiki using top right of this page links for apple /osx /rEFIt or similar.

Have not tried any of this recently.
Hope this helps.
