Ubuntu 12.04 using UEFI



I want to upgrade my machine with a new Motherboard, RAM and Processor.
I am planning on doing a clean install of Ubuntu 12.04.



The Motherboard I want to use is an
Asrock 970 Extreme4 which uses an AMI 32 MBit UEFI BIOS.



My Question is, is there anything I have to watch out for during the installation process? Cause I have read that some people have trouble booting into ubuntu using a UEFI BIOS. Any advice? I don't want to spend all that money for the different parts only to find out that I can only use windows properly.




Thanks in advance



IMHO, Ubuntu creates an EFI System Partition (ESP) that's a fraction of its proper size. I recommend creating an ESP in the range of 100-500 MiB, depending on various factors; but Ubuntu tends to make them under 50 MiB, IIRC. Ubuntu also creates FAT-16 ESPs, but the Windows installer flakes out when presented with FAT-16 ESPs -- it wants to see a FAT-32 ESP. These problems can be overcome by pre-partitioning (or at least creating the ESP ahead of time). Be aware, though, that Ubuntu 11.10 and earlier always erase the ESP, which wipes out other OSes' boot loaders. This problem has been fixed with Ubuntu 12.04. Thus, for an EFI install, I strongly recommend Ubuntu 12.04 over earlier versions.
