UEFI boot on my Asus k52f

I was reviewing my settings in BIOS and UEFI was disabled. I wanted to check what UEFI was so I googled it. I found out its like an upgrade to BIOS and improved boot speed. Currently I'm dual booting Ubuntu 12.04(32 bit) and Windows 7(64 bit). I'm currently confused as to how to make the switch since I don't want to make my System unbootable. How do I make the switch from BIOS to UEFI.

System Chipset : Intel HM55
Processor : Intel Pentium P6100 2 GHz

If you're prepared to wipe everything and start fresh it's not so bad. I recommend:

Clear the partition table (dd if=/dev/zero of=/dev/sda bs=512 count=1).

Partition with GParted, parted, or gdisk. Be sure to create an ESP with a FAT32 filesystem. Make it 200-500 MiB in size.

Install both OSes. Order is less important than on BIOS systems, but back up the ESP after the first install. Pre-12.04 versions of Ubuntu would wipe the ESP, and hence the Windows boot loader, when installing. That was supposedly fixed in 12.04, but I ran into it on my latest installation, so I don't think it's been completely fixed.

I wouldn't worry about the 2GB RAM, but it depends on how much stuff you run, really. Benefits will be minor -- mainly a possibility for an improved boot time and, once you learn it, easier boot manager maintenance. There'll be a learning curve, though. Check my Web page on EFI boot loaders for information on what's available and how they work.
