Thanks to "OldFred" and others I think I almost have this nailed down. I just have a couple other questions to sweep out of the way. These UEFI and GPT disks don't behave like the dual boot scenario of the MBR days hence my confusion.
Given feedback from other posts we see the 12.10 64bit ISO boots and installs with UEFI toggled on in system setup. SecureBoot needs to be off it seems. So far so good.
Pre-installed Windows 8 Laptop for a Dual Boot - yes there are many posts on this but I am missing just a couple minor points.
Here's where I am befuddled;
Leaving the pre-installed Windows 8 partitions in place (but making room for Linux installation), what would be the recommended partition scenario for the Linux install?
How big to make /home, /, /boot(needed?)
What other Linux partitions would be recommended in a pre-installed windows8 laptop scenario?
Does the Linux install routine in the UEFI scenario make use of the Windows8 EFI (ESP) partition to write Grub information or do we tell install to write this information in one of the partitions we created?
Does the Windows Boot Loader point to Grub now or is that Grub info somehow get written to the UEFI system setup?
How do we set the default OS and timeout (as in grub.cfg days).
Thanks in advance!
