How to fix bootloader?

2 posts in this topic

Recommended Posts

Hi

 

By mistake, Ive installed Chameleon bootloader on my Imac with 10.5.7 (thought this will only unpack it somewhere, not replace original one). Right now system is not booting. I`ve tried to boot from installation disk to fix it by using disk utilities, but it can not repair loader.

Is there any chance to fix it without reinstalling whole system and loosing all data?

I`ve found some tutorials on google, but it seems that they`re not working for me.

 

Thanks in advance for any help.

boot from the dvd and enter terminal

type diskutil list

find the disk number of the drive in question disk0 or disk1

 

next type

fdisk -e /dev/disk then the number like disk0 or disk1

example

fdisk -e /dev/disk0

 

next if you have partitioned your hard drive we need to know what partition OSX is on. 1,2,3,4,5,6 or whereever

 

type this one you know

 

flag partition number

 

example

if mine is one partition 1 i would type

 

flag 1

 

if it asks you to say yes during the next few steps say yes

type

update

write

exit

reboot and done
