I am trying to install a clean install of Ubuntu 11.04 desktop AMD 64
not dual boot

the bios on my Motherboard supports EFI
i have set EFI for CD/DVD boot for the Ubuntu live CD

Here is the hardware:

AMD A8-3850
Gigabyte GA-A75-UD4H
Gskill DDR3 1866 F3-14900CL9D-8GBXL (CL9-10-9-28)
WD 2TB sata - installing ubuntu on sda
WD 3TB sata - sdb
pioneer dvd


at first i thought the issue was support of the 3tb drive but i now have the same issue with the 2tb drive
a ran the ubuntu live cd install but when it reboots i dont get any menu
shows "loading operating system" this stays on the screen for quite some time and then i get a flashing cursor in the top left of the screen

i think it has something to do with the efi partition / grub2 on the boot drive
based on post the ubuntu 11.04 live cd doesn't create this properly

im really confused will all of the info on efi / grub boot partition

i was wondering if someone could direct me on the specific steps on how to get ubuntu to boot
i am a bit familar with linux but i have never had to struggle with boot issues

According to this document, UEFI still has some rough edges that are being worked on, so it's either going to take some elbow grease or (if available on your board) setting up BIOS-compatibility such that the standard GRUB/MBR setup will work.

My new server is EFI and boots fine with Ubuntu 10.04. I think I used a GPT partition table and created a GRUB boot partition so it could do its magic however it wanted.

But yeah, it's probably not as trouble-free as standard MBR installation yet.

Edit: of course I wish it didn't take three times as long to do the BIOS stuff as it does to actually boot once the BIOS is done with whatever it's doing.

Aaaaaagreed. Seriously, wtf? And what's with holding onto the limitations that try to ensure that the latest HW will boot CP/M?
