I am thinking about reinstalling Ubuntu 12.04 on a freshly formatted disk with BIOS changed to UEFI on my Asus laptop. I hope, it can boost my bootup performance, but am not sure whether it is worth the effort. What do you think?

Hardware specifications please? – Mitch Jul 24 '12 at 8:49
Intel(R) Core(TM) i3-2350M CPU @ 2.30GHz, 4GiB RAM, ATA Disk 320GB (4 Partitions: NTFS, HFS+, FAT32, EXT4 + SWAP), American Megatrends Inc. BIOS (K54C.207). Enough? – mcbetz Jul 24 '12 at 9:33

The main difference is the faster boot, and is that UEFI is better in communication with hardware & firmware. Below are some advantages of using UEFI.

  • Ability to boot from large hard drives
  • Faster boot-up time
  • Support for more than four partitions on a single hard drive
  • Better power managment

On a personal note, I haven't really noticed much difference using UEFI with either a SATA II or III hard drives, but a friend has noticed a difference using an SSD. If you would like to use UEFI go ahead and take a look at UEFIBooting

Note: In order to install OS in UEFI mode, you have to have a boot device which contains UEFI bootloader.
