how to boot up two or more hd with hfs+ partitions ?

[muitommy]

i have done research, but still figure out the possibilities to boot up more than one hardisk containing hfs+ partitions,

i have been using tboot/chain0 to locate my hfs+ drives,

but conflicts with happen if there are more than one hfs+drives exists

can i use grub to locate them? and how?

i need some advice or directions i can follow!! thanks

Why don't you just use your BIOS boot menu to choose which HD to boot?

 

F12 at bios post, then select the one you want....

 

or use the darwin bootloader.

that's link up to another problem ...

i encountered an error during the last step of bootfix (bless)

 

muitommys-acpi:~ Tommy$ sudo -s
bash-3.2# bless -device /dev/disk2s1 -setBoot -verbose

IOMedia disk2s1 does not have a partition UUID
DADiskRef disk2s1 has Volume UUID 4A3BED44-39F8-3C49-A4FE-C2C62D69F78A

Could not find IODeviceTree:/options

when i choose the hardisk, it gives me hardisk failure , non-system boot ... blar blar blar

so i use tboot/chain0 to locate my drives, but they seem can coexist in this configure ...

Grub works very well. I have used it to select btwn HFS+ partitions on 3 drives.

 

The easiest way is to use grub to load pc_efi.

PC_efi looks for hfs+ partition 1st on disk you booted it from. But you can enter hex code to boot a different disk.

 

Here is grub manual.

http://www.gnu.org/software/grub/manual/grub.html

It tells you how to do everything except load pc_efi, which is clearly explained in pc_efi readme.

 

However, doing grub without linux is difficult. And since pc_efi loads like a linux kernel using grub method, you need to put it on a grub readable partition (NTFS and HFS+ don't work).

 

So if you want to try this, install linux.

Then copy boot_v8 to /boot on your linux partition.

Then edit menu.lst in /boot/grub on your linux partition to add your os x partition.
