Hello there,

here we go with another technical question. When I reinstalled Ubuntu with the liveCD, I reformatted the hard drive with the built-in program gparted, to set partitions according to my will.

I noticed that there was an option for EFI boot or something like that, among the usual FAT32, NTFS, ReiserFS, Swap, Ext2 and Ext3. Would any techies out there care to explain what this EFI does?

Thanks!

Very generally EFI is a replacement of the aging BIOS system. I don't know how many computers have EFI. I believe the intel Macs have it.

Thanks a lot, phidia. Don't you think it's peculiar to find it in gparted?

EFI is the Extensible Fireware Interface, as phidia said, it is a replacement for the BIOS system and is used by Intel Macs. I believe it being in GParted has something to do with its boot manager which "An EFI boot manager is also used to select and load the operating system, removing the need for a dedicated boot loader mechanism (the OS boot loader is an EFI application)."

I wonder if I could create an EFI partition and put a graphical bootloader on it for my ubuntu much in the spirit of rEFIT for instance (http://refit.sourceforge.net/)

Or maybe install rEFIT altogether?

That's "Firmware" not firewire, and it isn't just used in intel macs but I haven't come across it in regular consumer PCs. Thw wiki article I linked did say it's used in those though.

The8thstar, I would plan on doing a lot of reading but it should be possible just not sure how well it will work for you.
I would look at this write up (http://en.wikipedia.org/wiki/GUID_Partition_Table) and also use the original link I posted.

Woah, that's way beyond me. Thanks for the link though, it helped me figure out that there is a chance for a possible implementation in the future.

Unfortunately, that will not happen with me. My computer skills are too basic for that (no pun intended).
