I want to install Final cut on the same computer I already have installed avid. As I do not want to create any conflicts with it, I thought it would be a good idea to install it in a different boot drive with a different mac os x system altogether. This way I can also try the new snow system without danger, and even test the new avid 4. software (when it became compatible ), because I am still using 2.x with 10.4. When I ran the installer it did not see my external esata drives, so I thought I could use another partition on the actual boot drive. But now I can not learn how to do it without erasing the entire disc, deleting my previous and precious avid installation. Can anyone point me to a solution, or telling me to forget it? I searched on the forum because I remembered many post about dual boot solutions, but is it possible to create it once you have already one? Many thanks in advance. Antonio

$45 .. but it works.

Well you could also just use "BootCamp Assistant" to create a FAT32 partition on your existing installation, you'll find it in your /Applications/Utilities folder. Then reformat that partition to HFS+ using DiskUtility, and then install the OS of your choice on it.

I would recommend cloning your boot hard drive onto an external drive before repartitionning, in case something goes wrong. You can do that using the excellent - and free - Carbon Copy Cloner.
