osX wont boot from burg?

[buzz86]

hay all

ive been dual booting ubuntu and xp for a bit now using burg.

i decided to get osx and the install went fine.

i had some grub issues but i got help with that here.

burg can see that i have osX and gives me the option to boot it, but when i select it my computer restarts.

i can only get into windows xp and ubuntu 10.4, but cant find a way to boot osX

ive read about a EUFI mode in the bios but dont really understand it and haven't found that option in my bios.

ive not got alot of Linux experience but will try anything to get my triple boot working.

does anyone know what i need to do. i dont no if i have to change how it boots or if its just a config file that needs changes made???

if anyone could help that would be great.

bellow is my hard drive layout just in-case.

burg = grub I suppose?

Google helps about this topic ("grub boot osx"): result. If this doesnt help, please post your grub configuration.

no burg is a graphical grub sort of, i dont no how to explain it. its a better looking grub. but it dont replace it, as far as i know it goes over it grub.


my grub menu is as followed but i dont no how that afects my burg list???


title Ubuntu 10.04

ive read about rEFIt and people are saying its like grub/burg but will work with os x but do i have top uninstall grub for that to work???

is there a way i can turn off grub for a test???

[rcgreen]

title OS X
root (hd0,2)
makeactive
chainloader +1

It looks like that should be

root (hd0,1)

if my osX in sda2 in my partition list then is it 2 or 1 im my menu.lst???

    Device Boot      Start         End      Blocks   Id  System

I'm not sure I understand what you are using to boot, never heard of burg?
If you were booting with Ubuntu 10.04 Grub, you would be using Grub2. With Grub2, drive numbering starts with zero and partition numbering starts with one. That being the case, your osx entry would be (hd0,2) and your windows entry (hd0,1). Since you show your windows entry as (hd0,0) and say it boots, something is missing here? Grub2 has no menu.lst file but does have a /boot/grub/grub.cfg file and the menu you posted looks a lot like a menu.lst file. grub.cfg has a totally different layout.

ok i see now that its 1. because all partition numbers start at 0.

neway it dont look like i can boot osx with grub so im looking for alteratives.

ive read about vista boot loader, that will boot vista, ubuntu (linux), and mac osX without problems, but i dont have vista and it isnt out for xp. so is there something for xp that i can use???

also does neone know about rEFIt as a boot loader???

thanks

i was using grub instead of grub2 so i could edit the menu.lst because i couldnt see how to do that with grub2.

would changing to grub2 help by any chance????

btw if you use grub and multi-boot i recormend burg

it makes your bootloader look great. if you google images "burg for grub" you will see.

or google it and read the article on omgubuntu.com

dunno if "burg" supports grub2. anyway grub2 is the more recent one and grub was officially replaced by it. anyway both CAN do basically the same, what changes is mostly the configuration part and how the internals work. surely nothing that affects the functionality, despite of some bug that was (and may never will be) fixed in grub.

from what I heard of, osX must reside in a bootable primary partition and may not be placed in a extended one (likewise where the unix one is in). so, just for being clear, you have following situation:

/dev/sda1 = bootable, as such got the MBR which refers to grub that is installed on the extended partition /dev/sda5. then you have the hsf/hpsf (osX) stuff on /dev/sda2 and around 452 free sectors at the end of the extended partition.

solution 1: which is what I would do

* dump the discs using dd, change the partition table and put the data there as follows
* dd osX to the head of the hard disc becoming /dev/sda1
* remove the extended partition which makes things only more complicated
* dd the unix stuff to /dev/sda2
* dd the windows stuff to /dev/sda3

these kind of operations is a quite complicated and can lead to data loss if you don't know which one comes first and why. so, if you are unfamiliar with fdisk, dd and parted AND you are not curious to learn them, DON'T DO IT. if you choose the path to enlightment, i strongly recommend to backup all of the important data and further a dd of the entire disc so that you can restore it if something gets banged up.

now solution 2 is a bit easier:

you may just make the hpsf partition bootable. i am unsure if it affects correct functioning of osX if the windows partition is still bootable. if so, you may need to remove the bootable flag from the windows partition, in the hope that windows still boots.

this is what needs to be done using fdisk:

fdisk /dev/sda (to launch fdisk)
a 1 (to turn off bootable for partition 1)
a 2 (to turn on bootable for partition 2)

once again, these kind of things are well documented and can be easily found using a search engine and without offense, LEARN USING GOOGLE. if this solved your problem, please mark the thread as solved and remember to share your freshly achieved knowledge.
