View Full Version : 12.04 UEFI install. How-to

April 27th, 2012, 12:43 PM
I have an ASUS E45M1-M motherboard and a 250GB SATA-disk. Is there a good Guide anythere? That Ubuntu have https://help.ubuntu.com/community/UEFIBooting
I think are very confusing for me, (I'm old and senil) there they mix Apple, MacOS, OS-X and other in the same guide, and there are also no time stamp, so if there may have being any changes, since for intance 11.04.
The UEFI-BIOS (They seems not to separate them in the ASUS manual.http://www.manualowl.com/m/Asus/E45M.../Manual/262972

Some qustions. On the machine now I have 11.10 64-bit but I think it's BIOS-boot (Get help before from Oldfred and also when I in UEFI/BIOS look at the boot-disk, it don't have UEFI-prefix) I have seem that there are something under SATA configuration (page 2-17 2.5.2) to chose between [IDE] and [AHCI]. It is now in [IDE]-mode. I have read that SATA [AHCI] demand UEFI and without it the disk get slower, and some other drawbacks. Now it takes a lot of time to just come to BIOS-post (several seconds).

Could it be because it use BIOS-boot instead of UEFI?

As I understand that if I want UEFI-boot
I need to make a FAT-partition with at least 100MB size.
Then I want a separate /home and swap partition and an extra partiton as spare, there I can install windows 7, If i don't get Ubuntu run very well with my AMD/ATI APU Fusion HD6320 (HD sound and video).

PS. I get the advise if I use BIOS-boot to make a Grub-partition on the disk but I did not succeded with that, and it worked anyway. That partition I made are WARNING-!-signed in Gparted.
