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?
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.
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.
