Anyone dual boot Win7/Ubuntu on a PC with UEFI?

[Diss]

Hi

I have been googling around for info on this but haven't seen anything definitive/easy, mainly just seen posts about it not working

Just wondering if anyone has a dual boot Win7/Ubuntu on a PC with UEFI and if so how they did it?

many thanks

edit : win 7 is already installed and i have a separate unformatted partition ready for a linux install

Hi,

I have the Asus Maximus X79 ROG (UEFI interface instead of standard BIOS) and have windows 7 and Gentoo installed. I installed windows 7 then installed the grub2 boot loader ontop of the windows 7 bootloader, just as you would a regular Bios. grub2mkconfig detects both OS's

You need grub-efi.

This is a good post if you haven't seen it yet:

thanks for that

the askubuntu link seems a bit too complex for me, but to follow up on some of your points....

my starting point is a single 2TB hard drive with:
a) win7(64) already installed (1.6TB)
b) plus i have an unformatted partition (415MB) ready for linux (Ubuntu 12.04)
c) plus the ususal “system reserved” partition of 100MB
mobo is ASUS P8Z68-V Pro with latest UEFI BIOS

I thought i better check out some drive details but got some very confusing info:
1) Using Gparted from Ubuntu 12.04 installation CD – it only sees a 1.82 TB drive all of which is unallocated!!! It doesn't see the NTFS partition or the system reserved partition. It says the partition table is GPT. (Oddly, the Ubuntu file manager does see the System reserved partition)

2) Using a Gparted live CD i get a sort of error message :
/dev/sda contains GPT signiatures indicationg that it has a GPT table. However it does not have a valid fake MSDOS partition table. Perhaps it was corrupted – possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the the GPT table and are now using an MSDOS partition table. IS THIS A GPT PARTITION TABLE?? --- i answered YES and saw the same info as in 1) above

3) The i tried a Knoppix live CD and got different info again. On the plus side the disk utility saw the windows/system/free space all fine. HOWEVER, i think it was saying the drive was MBR (rather than GPT).

Am now rather confused
