How would I go about installing Ubuntu 32 and 64 bit 12.10 on the same disk? I would really like to do this if you could help. I'm on Ubuntu 12.10 64bit ATM if that helps.

Edit: What I meant was installing the install cd for both 32 and 64bit on the same disk not the OS itself.

On a dvd-r

Here is wqhat I'm looking for:

Ubuntu 32 and 64 bit installation disk on 1 DVD -r so when a person puts the dvd in and restarts computer they enter a menu and have to chose which OS they want to install , the 32 bit OS or the 64 bit OS of Ubuntu 12.10

The 32bit install will actually run fine on most 64bit computers, so if you want to have a single DVD that can install onto "most" computers then you should just use the 32bit version only.

As far as I know this isn't a possibility. However, it is possible to boot multiple operating systems from one USB drive. I use a utility called MultiSystem (instructions here) which lets you drag and drop ISOs onto a USB and creates a GRUB bootloader on the USB to choose which system you actually want to boot.
