    I just installed Ubuntu on my iMac using Boot Camp and that is working fine. However I cannot boot OSX now. When turn the computer on, it goes to a menu asking me which OS to boot with. Ubuntu opens fine but when I choose OSX it does nothing and asks me to choose again. I have everything backed up on Time machine and have all of the OS discs for Leopard and Snow Leopard. I don't care too much about keeping Ubuntu, if I have to get rid of it, because all I've done so far is play Solitare. This is really starting to make me mad. I think I'd just like to get rid of Ubuntu completely because I don't really have a need for it I just wanted to see what a Linux OS was like. Thanks for any help, and I'm sorry if I put this post in the wrong section, I picked the first forum this sort of fit in.

    If you installed Grub on the hard disk's boot sector, you're in for a very bad surprise. Unless you install Linux on a dedicated hard disk, NEVER use the default option to install Grub on the boot sector.

    You could teach Grub to boot OS X instead of Linux - you basically only need to teach it where the OS X partition is located. However, this is some more advanced Linux stuff and you'll have to read some (not very good) documentation on Grub for this. I don't know it by heart, and it's been a few months since I've last configured Grub on a customer's server.

    But based upon what you wrote, you're probably better off with re-partitioning and formatting your hard disk.

    I don't get the point of installing Ubuntu on a Mac. OS X is UNIX & you can run just about anything that runs on Linux using X11/Macports. For testing or whatever, I would just run it in virtualbox or from an sd card.
