neotigZ Posted May 15, 2007 Share Posted May 15, 2007 ok i reinstalled mac for the 100th time. i have been tryin to update it and it would not boot back up so i would reinstall it. this time i decided not to do anything and its been runnin great well since the last time mac messed up windows stoped booting i been tryin to figureout how to fix it. but i just decided to install ubuntu. i installed it on the same hd as mac becuase it was a 160 gig drive and mac on used 128 of it. well after i installed it and rebooted the boot loader comes up and it has ubuntu, windows (which dont even work right now) and unknown os. which i figure is mac and when i click on it it says error 11 and to press any key. so whats wrong what do i need to do to fix? also let me know what other info you need. thanks to who ever knows what to do.

twophive Posted May 15, 2007 Share Posted May 15, 2007 Please rephrase what you did, in individual steps. Also, list your system specifics, such as : motherboard, processor, video and hard drive. Link to comment Share on other sites More sharing options...
neotigZ Posted May 15, 2007 Author Share Posted May 15, 2007 step 1 i installed mac on a 160 gig drive and it only used 128 step2 then i installed ubuntu on the rest of it step 3 osx will not work. step 4 it says unknown os in the grub. step 5 that pretty much sums it up. step 6 my pc specs mobo is ecs pa1 mvp cpu is a pentium d 2,6ghz vid card is a ati sapphire readeon x1550 (but in the system profiler it says its a x1300) 512mb ram is a gig its in a white case and had blue flashy lights in it Link to comment Share on other sites More sharing options...
twophive Posted May 15, 2007 Share Posted May 15, 2007 Have you looked at any dual boot guides using grub? Is your OSX partition primary? Check this guide, and double check your steps. http://wiki.osx86project.org/wiki/index.ph...e#Grub_in_short Link to comment Share on other sites More sharing options...

twophive Posted May 15, 2007 Share Posted May 15, 2007 You can edit grub directly, at the boot menu, by pressing E. Then once your done editing you can try booting it by hitting B. sudo su (password) passwd root (new root password) sync this is how to login as root, and change the root password. Good luck Link to comment Share on other sites More sharing options...

twophive Posted May 15, 2007 Share Posted May 15, 2007 I would, uninstall Linux reinstall windows set the OSX partition to boot and use the Darwin boot loader. You can specify a timeout at the menu, to select between operating systems. By editing this file : sudo nano -w /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and inserting : <key>Timeout</key> <string>#</string> # = How many seconds Who needs both Linux, and OSX when they're both Unix(unless you actually need to use linux for something).
