chain booting error

[kjur]

hi all

 

first about configuration: i have two HDs on the same ATA channel: the master one with winXP partition and another ntfs, the slave one with two hfs+ partition (main os x and back-up) and fat32 partition.

 

i use win xp booting to choose win or mac and then darwin booting to choose main or back-up mac partition.

 

i have chain0 copied to my win partition.

 

it used to be fine until i wanted to try 10.4.8 amd version. after this i got 'chain booting error' when choosing mac in windows booting.

 

the one way to boot up mac os x is to unplug my main HD and connect the slave one with os x as a master. even if i disable master controller, leave os x drive as slave and choose it in BIOS as a booting partition it doesn't work.

 

now i re-installed 10.4.6 instead of 10.4.8 but still got the same problem which is really weird because everything (hardware configuration and operation systems) is exactly the same as before when all worked fine.

 

any ideas?

 

btw. i want to install in near future ubuntu on slave HD, so there will be win xp, two partitions with os x and ubuntu. could someone advise me how to do it smoothly?

 

i tried to install easybcd but couldn't do it last night, don't know why.

The Disk Utility in 10.4.8 may have messed things up.

 

I would go to the 10.4.6 installation and use Disk Utility to erase (format) the 10.4.8 partition. Then reinstall 10.4.8, but don't select Disk Utility in the Utilities menu - just skip that step.

 

For bootloader, I would use the OSX/Darwin bootloader. Set the OSX partition (10.4.8 or 10.4.6) to active and be sure the drive with OSX on it is set to boot first in BIOS. Add the Timeout parameter to boot.plist. Test it out. If it works, go to your Windows drive/partition and remove the C:\chain0 line from boot.ini.

Rammjet many thanks for a reply.

 

it helped to remove all the partitions, make them again and install os x again to the main hfs+ partition. then i restored os x on the back-up partition from disk image using disk utility. both system were booting.

 

unfortunately after restoring old system on the main partition it has stopped booting again. i'm going to try everything again tonight, but instead of restoring main parition from image i'm going to try carbon copy cloner. i hope i will work.

 

btw: how to use darwin boot loader to boot windows? i have only two mac os x systems to chose in darwin. no windows partition. does it support booting linux as well as another OS?
