Thread: 9.10 installed - osx won't boot

-

hello all,

started ubuntu 9.10 live cd on mac book pro 13" late 2009.
once booted used "install" - icon on desktop install
ubuntu sdb (an 8gb sdhc card in sd-card slot).

selected manual partion table , explicitly chose installation
on newly created ext3 partion on sdb1 without swap.

during installation used terminal check was
installing on sdb1 (the sd card - not harddrive sda !!!).
went fine. @ end said was
installing grub @ hd(0,0) !!!! why ?

can't boot osx nor sd card.
booted install disk osx , tried repair disk,
sees osx partion , says "all fine", still can't
boot osx. pretty sure ubuntu's attempt install
grub ****** secret little efi partion osx keeps @ the
start of disk, knows how fix that?

might boot flags messed up, don't know.

when hold down alt-key can choose cd (either
ubunutu live cd or osx install cd) hard drive won't appear.

osx disk seems ok, looked @ terminal app from
osx install cd , can see everythink. think it's something
right "blessing" or fixing hidden efi partion. please help!

diskutil list provides:

/dev/disk0
#: type name size identifier
0: guid_partition_scheme *160.0 gb disk0
1: efi 209.7 mb disk0s1
2: apple_hfs osx 159.7 gb disk0s2

happy help.

thanks,
stephan

you can reinstall grub onto sd card specifying (hd1) root. fixing osx try this: http://www.insanelymac.com/forum/ind...wtopic=57650#2 or this: http://www.insanelymac.com/forum/ind...wtopic=57650#6

i booted system installation dvd , ran terminal. here typed (case sensitive):

diskutil unmount disk0s2
cd /volumes/osx86inst/usr/standalone/i386
dd if=boot1h of=/dev/rdisk0s2 bs=512 count=1
/volumes/toolsdvd/startupfiletool -v /dev/rdisk0s2 boot
bless -device /dev/disk0s2 -setboot -verbose
diskutil mount disk0s2
bless -mount /volumes/osx86/ -setboot -verbose
reboot
* terminal (in utilies @ top of first screen)
