Hello I have now tried installing Fedora 16 about ten times without any look of actually booting up. I get a device not found then the grub rescue >

I have installed using the auto mode even and no luck. Traditionally what I have done is have two hard drives in my laptop, one being an ssd. On the 320 HD I set a 500 mb swap and the rest as /home as ext 4. On the ssd I set a 2mb formatted boot, and the rest of the 32GB as an ext 4 mounted at root.

Nothing seems to work, I really wanted to run Fedora after running it virtually for a while now, but am ready to load Mint, but before I do that I hope someone has an idea of what I am doing wrong here. Thanks for the help

2MB for boot? I'm sure you need a lot more than that! Or is that not what you meant? In any case, I recommend that you don't format a boot partition at all. Just a root partition, swap and home. If I'm not wrong, fedora will put the boot stuff in the root partition.

As grub2 is installed and your system is booting it (hence you get the grub rescue prompt), it may be that grub2 cannot find the files it needs in /boot to load the kernel and initrd to get the rest of the system booted. If your /boot is only 2MB, there's probably nothing in there for grub2 to find! Anaconda (the installer) ought to have given you a warning about this, but it may well not have and tried to continue the install anyway.

Try the install again, with at least a 500MB /boot partition. Depending on your system, you may also need a 2MB "BIOS boot" partition at the start of your disk.

I think the problem is that I am doing that from a live cd, but want to control where items are placed. Right now booting from a ubuntu live cd and it keeps telling me it can't find root even though I am sitting in it.

You could try running a live image (CD/DVD or USB) then installing using the "install to hard disk" link from the live desktop.
