    I get an error when I select the disk to install it on. It shows a yellow triangle and when I click the disk it says it can not install because this disk can not be used to startup this computer. I have the disk portioned OSX on one side, Ubuntu on the other and use rEFit to boot, so I thought rEFit was the problem and removed it and still can't install. So i deleted my Ubuntu and reformatted it, still will not install. I keep getting the error, this disk can not be used to startup this computer. I when to startup and made sure it was selected as the startup disk and it is, but it still will not let me install.

    Any ideas? Also how can I re-combine those two partitions without loosing anything? I don't have an extra drive right now to backup to, so I cant just erase and start fresh.

    Verify/Repair Disk, Check for MBR or GPT, Time Machine Backup first

    Some basic thoughts.

    I'd do what Tes said. Make sure the disk is formatted HFS+.

    when the disc first launches

    click utilities<disk utilities<(select internal hdd on left side bar)<partition<1 partition (more if you want)<options<GUID partition (first one)<click ok< click partition. this should fix it.


    oh ya make sure you are partitioning the drive as mac OSX (journeled)


    P.S you will loose everything.

    Figured it out. I used MBR partitioning when I setup my linux dual-boot. Apparently apples install disks need GPT partitioning and will not install on anything else. The solution is make a carbon copy of my leopard install re-partition my drive using GPT partitioning and putting that carbon copy back, the snow leopard will install just fine.
