Do I understand this correctly?
When you install multiple distros on a UEFI system you only have to share the ESP.
Each distro will use its own Grub.
The finished /boot/efi/EFI will contain a folder for each of the 3 distros.
ex. /boot/efi/EFI/redhat
/boot/efi/EFI/debian
/boot/efi/EFI/ubuntu
The reason I ask is that Auntie Google hasn't been that helpful. Instructions for installing a distro as a second or third OS on UEFI is sparse.
I have a 120GB SSD that I would like to use as a place for the ESP and the root folders of three distros. I have a 1.5Tb hard disk that I would like to use as a place for the three /home partitions, and, possible the three /var partitions, if it will lengthen the life of the SSD.
The UEFI bios should be able to boot each distro from the information in the ESP, so I won't have to play with Grub2 or a common /boot directory. At least, so far, this is how I understand it.
The topping would be to install rEFInd to call either of the three distros during boot.
I have Fedora 17 running in UEFI mode at present off of the hard disk. It still uses legacy grub and it created a fat16 partition for the ESP when I asked it for a fat32. It also needed to use ext3 for /boot instead of ext4. Not that either was ever a problem, but, I would like to start fresh. Which means making the newly installed SSD sda and the hard disk, sdb, and re-installing from scratch.
So, has anyone done a dual or triple boot using UEFI? Any suggestions? Do I RTFM again, or, am I close? Any suggestions, comments or links would be appreciated. I've read through the info posted by Rod Smith at: http://www.rodsbooks.com/efi-bootloaders/index.html to get my feet wet with UEFI. I'm sure it wouldn't hurt to read it again, but, getting some first hand testimonials would also be nice.
Thanks in advance.
