I have a Dell PowerEdge T110 (Xeon 1220v2) server with no OS. From my mac, I was able to save the Ubuntu 13.10 for server iso (x86) and used UNetbootin to save the iso to a USB stick (2GB).

I was hoping to boot the server from USB, and all seemed to be going well, BIOS even detected my USB drive when I plugged it in, but for some reason I'm getting a "Missing operating system" error. I checked the USB drive and it appears that UNetbootin put the correct files on it form a cursory glance (although I'm not entirely sure what I should be looking for).

Should I be able to boot a server with no OS from a UNetbootin created Ubuntu 13.10 USB? And if so, why might BIOS not find the right files?

I had read that there is a USB Emulation setting in BIOS, but I haven't been able to find this in the menus. My understanding is that by default, this is set to on.

I might try wiping the USB stick and running UNetbootin again. The USB is formatted to MS-DOS FAT16 (should it be formatted some other way?).

I think you should format your USB stick by FAT32.

Maybe this article will helping you.

  • I will try that. In theory I think it should work with either FAT16 or FAT32, but FAT32 makes more sense.

Ultimately I believe that this USB stick was not "bootable"

To give everyone some more background, this was a corporate give away usb stick. Even when I pointed the BIOS to the external usb drive, it failed to load.
