10.4.8 images don't work with my grub!

[ramoncio]

I installed some time ago my OSX86 and everything worked fine at first time.

I use grub as boot manager for Windows, OSX86, Kubuntu and Geexbox.

Everything was fine since I decided to install last JAS 10.4.8 DVD.

After the installation, when I try to boot OSX86 partition I get a grub error.

 

Filesystem type unknown, partition type 0xaf.

chainloader +1

Error 13: Invalid or unsupported executable format

 

I've tried with

rootnoverify (hd0,1)

also with

chainloader --force +1

even with

chainloader /chain0

and their combinations, but no success...

 

It seems grub is unable to recognize the new 10.4.8 kernel as a valid one to boot, as far as I've been able to research at the internet for grub error 13.

Does anybody have noticed the same error?

Any solutions?

I'll try upgrade grub to latest version and see what happens.

Any help will be appreciated.

 

Cheers!!

tried this?

 

root (hd0,1)

makeactive

chainloader --force +1

 

i assume you have the right partition id above.

if it doesn't work, try using grub's cli to determine if you have the right partition id.

 

also share your partition (physical) order and type with which os.

Thanks for the fast answer!

Sorry for the lack of vital data.

I just was wondering if somebody knew about this grub problem.

 

The partition table is:

(hd0,0) hda1 ntfs 15gb WindowsXP Active

(hd0,1) hda2 0xaf 10gb OSX86

(hd0,2) hda3 ext3 210gb DATA

(hd0,3) hda4 ext3 25mb Contains Geexbox with Grub

All of them are primary as you can see.

 

When I try with your options I get:

 

Loading stage 2..

 

Grub loading, please wait.

Error 18

 

 

Everything works fine with darwin kernel version in 10.4.6 dvd , but 10.4.8 darwin kernel seems different...

[cbmkgd]

Check the meaning of this error: Error 18

 

But that wouldn't explain why it worked with 10.4.6...

[ramoncio]

Maybe too big hard drive? 250gb...

Don't think so.

It shouldn't work with 10.4.6 neither.

But it does!

I have reinstalled 10.4.6 and works again.

It must be some grub problem with the new Darwin kernel image...

I'll try to install 10.4.8 again without intel sse3 semthex kernel image, but with the generic one and see what happens.

I've been reading this about grub error 18.

I bet a part of the problem is having the Geexbox partition at the end of the hard drive (last 25mb). But I can boot Windows and Geexbox without any problem. It even works with 10.4.6!!

But when I boot 10.4.8 with the options you gave me:

root (hd0,1)

makeactive

chainloader --force +1

I get grub error 18.

 

I'll try later to change Geexbox to the begining of the hard drive to see if this avoids error 18.

 

I've tried to install 10.4.8 without semthex kernel but same results.

Grub error 18.

Now I'll try to change the boot partition to the begining of the hd.

the problem is not with your linux partition but the macos one... so there's no need to move it on the beghinning

anyways... try this

 

rootnoverify (hd0,1)

chainloader (hd0,1)+1

hi,

 

I had the same problem booting any jas 10.4.8 dvd installation. If you use disk utility from 10.4.8 to format your OSX you won't be able to boot any partition. Boot an older Jas DVD (for example 10.4.6), format your destination drive and reinstall 10.4.8 without repartioning or erasing your 10.4.6 made partition. This is from

Ramjet, that helped very much. Don' forget to make your OSX partition active.

Thanks a lot macintoshy, you are fully right!!

I formated from 10.4.6 DVD's disk utility and installed OSX86 from 10.4.8 JAS DVD and everything was ok with grub.
