I have Windows and Ubuntu (installed with Windows Installer) on this computer and I'm trying to boot Ubuntu 12.04 Desktop amd64 with a Live USB as the partition Ubuntu is on is too small. The boot worked fine on another computer, but for some reason this computer is getting stuck indefinitely at "Loading Operating System . . ."

This computer doesn't have a CDROM, so USB is the only option. Checked the ISO to ensure it wasn't corrupt. I have tried several different programs to make the Live USB, with the same results each time. I went into the BIOS and changed the boot order to recognize the USB first, same results.

When Windows was installed, it was booted off of a USB without any problems. Any ideas as to why it just won't load Ubuntu?

Sometimes changing usb emulation in the bios from auto to CDROM works. Try that. Did you just dd the iso to the usb stick? – Matt H Sep 19 '13 at 22:43

Without knowing any details about your hardware config, and anything about the programs you have used, I'd recommend trying more programs to make a bootable USB drive. I usually use Universal Usb Installer, which worked flawlessly every time I tried it.

One thing I'd recommend: check the USB drive for partitions. If it's partitioned, the programs you are using might fail to write the files correctly leading to a hang.

Thanks for the reply KuraiHikari, I'm trying the 32 bit version using UNetbootin now. I formatted the USB each time before trying a different boot, and it doesn't appear to be partitioned. Not sure how to show hardware config but...

If anything else fails, you can try installation via the network. – Dumitru Sep 19 '13 at 23:12
Ah, good idea. Thanks again! – Mitch Sep 19 '13 at 23:14
I used a new USB and got it working. Just wanted to come back and say thanks KuraiHikari. It looks like it was a partitioned USB that was causing the problem. No idea why it effected this computer, but not the other. Thanks again! – Mitch Sep 22 '13 at 23:01
