Boot from a hard drive which has 4 partitions (not immediately important)?

**SBDxAric** · February 18th, 2009

This isnt immediately important, i know theres many more emergency situations...

But i have formatted my usb hard drive into 3 partitions:
J: FAT32 74.23 GB 60.80 GB PRIMARY
* UNALLOCATED 75.40 GB LOGICAL
K: UNFORMATTED 74.23 GB LOGICAL
L: UNFORMATTED 74.23 GB LOGICAL

J: Is my regualar backups and stuff

K: i plan to move wubi onto
L: I plan to install Leopard on it.

I just wanna know how i will choose what to boot from?
When i restart, will it go straight to K:, or will i have a choice K: or L

Basically, it will attempt to load the OS as directed from your MBR, so the last OS you install that updates the MBR will win -- because each one, unless you have options to choose otherwise, will overwrite the MBR when you install it.

Is there any way to fix this? Or will it be randomized what will boot up?
Another question, will i have to make J: logical and not primary?

Fix what? I told you how the booted OS is decided -- by the last OS installed. Can't answer a generic question about how to change that AFTER installation because it depends critically on what OS is last -- and you're talking about installing a Mac OS -- and this is the Ubuntu forum, not the Apple forum.
