Could you proceed in live mode and click the "install" icon? It might prompt some errors so we can find out what is going on

reburn and maybe redownload the 32bit ubuntu live cd and then chose "safe graphics mode" then click the install icon.

I have the same problem I get the:

This kernel requires an x86-64 CPU, but only detected an i586 CPU. Unable to boot - please use a kernel appropriate for your CPU.

error too when installing it wont load the kernel.

Did you managed to boot from the live cd and checked the system, using programs, connect to the net and so on ,,,,?

Nope. When ever I
"try it out" or
"install"

I get the kernel error.
