Triple boot snowosx GM v3.5, win 7, ubuntu 9.10

[Dragonsky]

Ok i'm pretty lost so if anyone could help me

 

First I was following the guide here Triple Boot Guide but not 100% since I don't have a miniDell.

 

I have a hp dv5t-1000 instead.

 

This is the steps I've took:

 

boot Win7 DVD

 

run Diskpart.exe

 

1. list disk
   
2. select disk (your hard drive, should be 0)
   
3. clean
   
4. convert GPT
   
5. create partition EFI size=200
   
6. create partition primary size=(size in mb for OSX - mine was 50000 MB, of a 160 GB HD)
   
7. create partition primary size=(size in mb for Win7 - mine was 50000 MB, of a 160 GB HD)
   
8. list partition (a * should appear on the third partition, that's where you will install Win7 later)
   
9. format fs=ntfs quick
   
10. exit
    

Install OSX:

 

run Snowosxinstall GM v3.5 DVD

 

Use Disk Utility (from the tools menu) to "Erase" the OSX partition to HFS+ (Mac OS Journaled File System), name it OSX

Install OSX to this partition

The next step it said re-run NBI and I don't know what is it so I just stop there and move to next

 

Install Win 7:

 

Boot from Win7 DVD, I've install it to the NTFS drive

 

Install Ubuntu:

 

Boot Ubuntu 9.10 64bit and install sucessfull.

 

After that i got Grub menu with the list of drive when boot up.

 

I could follow the guide next because my ubuntu have Grub2 so i did NOT do

 

the following:

 

1. open terminal (accessories, terminal)
   
2. sudo grub
   
3. find /boot/grub/stage1
   
4. root (hd?,?) [from before, probably (hd0,3)
   
5. setup (hd0,3)
   
6. quit
   

But I did the last 2 steps which is:

 

sudo apt-get install gptsync [it's not on the install image]

sudo gptsync [recreates the hybrid mbr]

but when I type sudo gptsync /dev/sda I got an error state I can't do on this disk because of the EFI partition or something like that.

 

So....now i can only chose the Ubuntu from the Grub to run. I try to run the OSX got the error, same with Win 7.

 

What should I do now ? to get my Snowosx GM v3.5 10.6 working ? normal I just need to run the DVD and then go in the terminal, type cd / , and then sh MakeDSDT [name of my drive] and then it would boot from Darwin. Since I want to have a nice looking booter at the begining i try to following that guide above.

 

Please help me out, what steps I should do to make this work. Do i have to clean the whole drive and start over with a new guide ? Thanks

...The next step it said re-run NBI and I don't know what is it so I just stop there and move to next....

 

NBI (NetBook Installer) is a kind of a bootloader for netbooks so you can boot/install OSX. NBI specifically is not that important to follow this guide, there are others tools to make it.

 

hope this helped to clarify a little.

I can't help you with everything; but....

 

Install Ubuntu:

 

Boot Ubuntu 9.10 64bit and install sucessfull.

 

After that i got Grub menu with the list of drive when boot up.

 

I could follow the guide next because my ubuntu have Grub2 so i did NOT do

 

the following:

 

1. open terminal (accessories, terminal)
   
2. sudo grub
   
3. find /boot/grub/stage1
   
4. root (hd?,?) [from before, probably (hd0,3)
   
5. setup (hd0,3)
   
6. quit
   

 

This installs GRUB in the Linux boot partition. It sounds like you've already got GRUB installed, though, just not configured right, so I don't think this is a problem....

 

But I did the last 2 steps which is:

 

sudo apt-get install gptsync [it's not on the install image]

sudo gptsync [recreates the hybrid mbr]

but when I type sudo gptsync /dev/sda I got an error state I can't do on this disk because of the EFI partition or something like that.

 

The gptsync tool is a bit limited. Try my GPT fdisk instead. Check the sub-page on hybrid MBRs. Create a hybrid MBR for your Windows partition(s) and any shared-data partition(s), but nothing else. Both OS X and Linux are fine with GPT. If you've got room on the disk, I recommend creating a BIOS Boot Partition, too. These can be quite small -- about 100KB. GRUB2 will use this if it's present, and it can improve reliability. (I doubt if the absence of such a partition is the cause of the problem you report, though.)

 

So....now i can only chose the Ubuntu from the Grub to run. I try to run the OSX got the error, same with Win 7.

 

What error? Post the exact error messages you get for each system. There are about a million things that could be wrong at this point, and the error message is your first step in tracking down and fixing the problem.

 

One piece of general advice concerning boot loaders: Between every OS install or before every boot loader installation, back up your MBR. This is the first sector of the disk, and most boot loaders put part of their code there. When you multi-boot several OSes, most of them overwrite the previous OS's MBR-based boot loader code. This is OK in some cases, since the new boot loader may enable booting the subsequent stages of the previous OS's boot loader, but sometimes that doesn't work so well. Having a backup of the previous boot loader's MBR can enable you to work around such problems in various ways -- by restoring the backup or by telling the new boot loader to load and run the backup image you've created. To do the backup, use the dd utility in Linux or OS X:

 

dd if=/dev/disk0 of=backup.mbr bs=512 count=1

 

This is how you'd use the command in OS X. In Linux, change /dev/disk0 to /dev/sda (or possibly /dev/sdb, /dev/hda, or some other disk identifier). Specify a different backup file each time -- say, windows.mbr, osx.mbr, and linux.mbr.

I had been trying to make grub 2 to load OSX, something is breaking in grub itself.
