Patrick_ Posted August 29, 2005 Share Posted August 29, 2005 Hey all... I have Mac OSX on an extended partition. It's type is AF. However, when I try to boot with grub, I get and "Error 13: Unrecognized device" Is it because it needs to be on a primary partition? I have GRUB configured correctly.

Hierophant7 Posted August 29, 2005 Share Posted August 29, 2005 I don't really know much about extended partitions. I'm pretty sure you're not supposed to run an OS's root filesystem from an extended partition, but I may be wrong.

Patrick_ Posted August 29, 2005 Author Share Posted August 29, 2005 Thanks. I tried it on a primary partition, also, and it still happened. It says "Error 13: Device string not valid". What the heck does that mean? Link to comment https://www.insanelymac.com/forum/topic/1473-grub-errors-wont-boot/#findComment-9211 Share on other sites More sharing options...
Hierophant7 Posted August 29, 2005 Share Posted August 29, 2005 Thanks. I tried it on a primary partition, also, and it still happened. It says "Error 13: Device string not valid". What the heck does that mean? <{POST_SNAPBACK}> If you're getting "Device String Not Valid" then it's likely the GRUB doesn't like the way you entered the device string in GRUB (duh.) It might also mean that the device your grub.conf (or menu.lst) file is pointing to does not exist. Remember that with GRUB, 0 is used for the first partition number, not 1. Thirdly, it could possibly mean that you don't have an OS installed on the partition your grub.conf is pointing to. I was just looking at a post that showed how to configure GRUB. I'll see if I can pull it up. In the meantime, could you post your grub.conf? I know you said it was configured right, but I'd like to take a look. If it really is configured properly, then the operating system is not installed properly on the drive you're pointing grub at.

Hierophant7 Posted August 29, 2005 Share Posted August 29, 2005 K, I found two grub configurations that might work (I haven't tried them myself, but I will eventually. Linux is currently off my computer while I mess around with different DVD and harddrive images and such) title MacOSX root (hd1,1) chainloader --force +1 title Mac OS X rootnoverify (hd1,0) chainloader +1 Of course, make sure you use the correct (hdx,y) numbers. 0 is the first partition, 1 is the second, and so on. It's the same for the drive numbers... hd0 is hda, hd1 is hdb and so on.
