On a new computer build, I installed 12.04 Desktop 64bit from a usb stick. When I rebooted, it hangs. It writes "Grub" on the upper left and then nothing else.
The bios setup program has boot options for "efi: [hard drive id]" and "[hard drive id]". They both result in a hung boot.
Any ideas on why its hanging and how I should change it?
During the install I removed the old hard disk partitions and created the following partitions. 40GB ext4 used for ubuntu 12.04 root 40GB empty (I plan to install windows 7 later) 4GB swap 80GB fat32 (for data accessible from ubuntu and windows).
Hardware is... GIGABYTE GA-Z77X-UD3H Intel Core i7-3770 2x 8GB RAM 160 SATA hard drive
Update: I booted Ubuntu Live, installed the Boot-repair PPA, ran it and it fixed the boot problem.
I also think I now know why this happened. I did manual partitioning (i.e. the "Something else" option) and I did not pay much attention to the dropdown box near the bottom. I now realize that that box determines where the boot loader goes. I think I had it set to the wrong partition.
