I downloaded the Linux iso and burned it to a CD, but before I boot from it, I want to know how/if I choose which partition Linux gets installed to. I have Linux Ubuntu 10.10 and Mac 10.5.8.
Yes - the GUI installer will ask if you want to partition, which disk partition you want to install to, and where you want to install the bootloader. I can't remember if the CLI installer does all three, but it WILL definately ask which partition to install to.
Just to be safe, i recommend doublechecking the release notes, for errors, but it should work, and warn you before doing anything
