Ubuntu server 14.04

I have a Dell Precision T7400 with onboard SAS controller. After installing Ubuntu from LinuxLive USB USB drive, the machine freezes at the boot screen. I don't get any splash screens; this is happening well before that. There is no drive activity at all.

The weird thing is that if I leave the USB key in the USB port, it all boots up fine, and I get to my Ubuntu prompt with no problems. The BIOS boot order is the USB first and the local drive second. I have not configured any RAID with the SAS controller.

I had Oracle Enterprise Linux installed (6.4) and it works no problem.

It was a very simple error - GRUB was on the USB. It was a very simple fix; I just had to boot as normal with the USB connected and then run this command:

sudo grub-install /dev/sdb 

(on my machine, sdb was the install target drive)

It's all working nicely now

See this post on Super User for more details Ubuntu Server installed from USB puts GRUB on the USB drive instead of the hard disk.
