I'm trying to get UEFI boot on my ProBook 4720s. Because I swapped the HDD for a SSD I had a blank canvas to start.
The 12.04 Live DVD refuses to boot into UEFI, as do Alternate and desktop CD's. However, when I make a 16Gb flashdrive into a live FS using the bootdisk tool in ubuntu, I can boot from USB, manually into UEFI mode. It even sidesteps to DVD as medium when I boot from USB with 12.04 Live DVD present.
I installed a GPT partitiontable with part 1, label EFI, fs FAT32, flag BOOT, mounts at /boot/efi part 2, label Linux-ROOT, fs ext4, no flags, mounts at / part 3, label Linux-SWAP, fs swap, no flags, mounts as swap
So far, My system refuses to boot from harddrive by itself. I have to select "Boot from EFI file" and manually browse to (HD0,GPT1)\EFI\ubuntu\grubx64.efi any other option ends in "no system disk, please insert boot disk"
I tried installing BURG, but that merely enforces non-efi boot.
I tried most of the solutions I could find, but one says \EFI\grub\grub.cfg next says \EFI\ubuntu\ubuntu,cfg
I'm confused and getting frustrated. How do I correctly install Ubuntu 12.04 in UEFI mode on this machine???
