thespottedelf Posted September 16, 2008 Share Posted September 16, 2008 Well, lets say I'm not a fan of linux at the moment, I had my Osx86 and windows installs running beutiful so i decided to get a bit adventurous.... When i installed osx i made 20gb partition free incase i wanted to play with some linux (get to know it). i just installed opensuse 11 with grub. Install went fine, but wouldn't you know Osx won't come up in grub. I tried everything to add the osx partition to grub (its /dev/sda1) but no matter what it comes up with an error (hfs partition error) Am i f'd in the a, or can this be fixed?

thespottedelf Posted September 16, 2008 Author Share Posted September 16, 2008 if i where to boot onto a kalyway disc and erase the linux partition would that do it? or installing a second kalyway over linux? cause at this point, all i want to do is get my data off my osx partition and re-install everything Link to comment https://www.insanelymac.com/forum/topic/126388-grub-problems/#findComment-893830 Share on other sites More sharing options...
Alessandro17 Posted September 17, 2008 Share Posted September 17, 2008 This is what I would do: Windows XP installation CD->Recovery Console-> "fixmbr", "fixboot". Install Acronis OS Selector. Your OS X partition should be listed. Never install GRUB to the MBR. Install it to the root (/) partition instead.

thespottedelf Posted September 17, 2008 Author Share Posted September 17, 2008 well, i can't get into the recovery consol because it asks me for an adminstrator password, i give it and it doesn't work... so i booted back into windows and took my password off my account, it still won't work... i tried every password i would have used and i can't figure it out...

kulos Posted September 17, 2008 Share Posted September 17, 2008 I boot my OS X using grub. Setup: One disk with win XP and Ubuntu, MBR: GRUB. Another with OS X (GUID). Grub (MBR) boots OS X with kernel parameter pointing to the "boot_v8 file" (EFI) on a partition that is readable to grub (ext3 in my case) on my OS X hdd. (Same disk as OS X installation = Avoid 0x80/0x81 problem) Grub rules! kulos Link to comment https://www.insanelymac.com/forum/topic/126388-grub-problems/#findComment-895226 Share on other sites More sharing options...

ulin Posted September 18, 2008 Share Posted September 18, 2008 grub won't boot osx unless you give it a link with efi. do the following wiht root user on linux (ie: open terminal, type "su -", password, then start stuff from that terminal ie. type gedit to edit text files, type firefox to start firefox as root: 1. download pc_efi_v80.tar.bz2 and get the booti_v8 file from it (search here or google or try http://www.mediafire.com/?0xxzx0xsumg) (extract with the command tar xjfv pc_efi_v80.tar.bz2, cd into it) 2. copy the file boot_v8 to your /boot/ directory (cp boot_v8 /boot) 3. edit /boot/grub/menu.lst, at the bottom of the file add: title macosx kernel (hd0,1)/boot/boot_v8 root=/dev/sda1 replace (hd0,1) and /dev/sda1 with your linux partition (NOT osx partition). Check out the file /boot/grub/device.map to see what (hd*) is mapped to what /dev/sd* in Grub. Usually Grub maps your /dev/sda1 to (hd0,0) (so grub counts from 0 where /dev stuff counts from 1) if you want windows as well (though I think yast'll write this in automatically) add this: title windows rootnoverify (hd0,1) chainloader (hd0,0)+1 replace (hd0,0) with your windows partition and (hd0,1) with your linux one when you got all this down in pc_efi screen which will come up when you chose it in grub menu on boot, hit esc and type in 80 for your /dev/sda, 81 for your /dev/sdb etc, targeting whichever physical hard disk device has your osx install on it.

thespottedelf Posted September 18, 2008 Author Share Posted September 18, 2008 Try blank password works for me sometimes. thanks it worked a lot... well i decided since i don't "have" to have linux i'm not goin to play with fire i realized now, that i have 3 bootloaders set up on my computer, which isn't a good thing... i followed the wingrub tutorial, which didn't work (or so i thought) then while playing with the grub settings i got it to boot into wingrub, which i got to forward me to the kalyway boot up menu... so i got into osx and moved my important files onto my parents external (havn't gotten mine yet ) now i'm going to reformat and reinstall everything, thanks for all the help!

Alessandro17 Posted September 18, 2008 Share Posted September 18, 2008 i realized now, that i have 3 bootloaders set up on my computer, which isn't a good thing... i followed the wingrub tutorial, which didn't work (or so i thought) I am a lazy {censored}. That is why I always go for the most simple solution which, IMO, is allowing Windows to own the MBR and multiboot with Acronis OS Selector. That is why I recommend to install GRUB (if you want to try Linux) to the root (/) partition, not the MBR. This is the default for Mandriva Linux, one of most user-friendly distributions.
