johnniecarcinogen Posted June 19, 2007 Share Posted June 19, 2007 If you have a blank cd, try downloading and burning the gparted live cd (its useful to have anyway). When the cd boots, it gives you options to boot other disks/partitions. You can try this without installing anything and if it won't boot OS X, the problem probably isn't grub but something with the OS X instalation.

avengedsevenfold fan Posted June 20, 2007 Author Share Posted June 20, 2007 thats considered multi booting. Link to comment Share on other sites More sharing options...
avengedsevenfold fan Posted June 20, 2007 Author Share Posted June 20, 2007 When I boot from the live CD, the same thing happens. "Invalid or unsupported executable format". But the CD uses GRUB also, so I would expect this. Link to comment Share on other sites More sharing options...
cbmkgd Posted June 20, 2007 Share Posted June 20, 2007 ok, try this: set your first partition (hdb1) active on the second drive (it may already be so, since I see the star* besides that partition in your list); and then when you reboot, press the appropriate key to see the menu your BIOS gives to select which drive to boot first, and boot on that second drive. If that works, then you may have to use the mapping as was done for your windows on third drive (which shouldn't really be necessary, but why not try). If it doesn't work, well, I don't think grub is the problem. Link to comment Share on other sites More sharing options...
avengedsevenfold fan Posted June 21, 2007 Author Share Posted June 21, 2007 all my BIOS says is "Boot from SATA hard drive" . Link to comment Share on other sites More sharing options...
Tommy Posted June 21, 2007 Share Posted June 21, 2007 base on your partition table you should use Title Mac OS X root (hd0,1) chainloader +1 no need for makeactive is you can see that /dev/sda2 is already active. let me know if you still have problem Here are the results of the fdisk: Disk /dev/sda: 80.0 GB, 80000000000 bytes 255 heads, 63 sectors/track, 9726 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 5 40131 de Dell Utility /dev/sda2 * 6 9119 73208205 7 HPFS/NTFS /dev/sda3 9120 9725 4867695 db CP/M / CTOS / ...

cbmkgd Posted June 21, 2007 Share Posted June 21, 2007 his osx is on dev/sdb1 * 1 15272 122672308+ af Unknown so it's (hd1,0). Confirmed by what he said earlier: OS X is on my second drive, on my first partition. Linux is on my second drive on my second partition. If the star means 'active', then indeed the makeactive line isn't necessary. Link to comment Share on other sites More sharing options...
johnny_0_o Posted September 1, 2007 Share Posted September 1, 2007 Hi, I have a problem that seems like really similar to this tread and I would like your help on this. I have 3 drives in my pc, one I installed osx entirely on, the other one I installed xubuntu on it entirely and the third for data (old windows ntfs partition without OS). After installing xubuntu I an not able to get back to osx. I put the gparted cd in and here is the fdisk -l: /dev/hdc1 boot -> osx /dev/sda1 boot linux /dev/sda2 extended /dev/sda5 linux swap /dev/sdb1 sfs (ntfs data) I would like to know how to reconfigure grub so I can have osx in the choices at boot. linux is actually configured as (hd0,0) in menu.lst Thanks for your help.

cbmkgd Posted September 1, 2007 Share Posted September 1, 2007 Well, find out if your hdc1 is (hd1,0), or (hd2,0), etc, and adjust accordingly. (eg use the grub utility to check it out) Link to comment Share on other sites More sharing options...
johnny_0_o Posted September 1, 2007 Share Posted September 1, 2007 So you mean there is a grub utility, a GUI? to verify the configuration? is it in synaptic? I could also make a fey copies like this... title MacOSX(1) root (hd1,0) chainloader +1 title MacOSX(2) root (hd2,0) chainloader +1 title MacOSX(3) root (hd3,0) chainloader +1 Just until I find one what actually works then remove the others... Thanks Link to comment Share on other sites More sharing options...
cbmkgd Posted September 1, 2007 Share Posted September 1, 2007 yes, trial and error should help you find the right one. as for the "grub utility", well, i should have said "grub prompt" to be more exact... when you boot with grub, from the menu there should be a way to get the grub prompt (eg pressing the 'c' key). check this (old) article to get some info about what you can do with it (as it could help in the future, osx or not).
