I recently upgraded my setup and I now have a working Ubuntu/Win 7 dual-boot setup with UEFI. I'm running an Asus P8Z77-V with UEFI, and to alleviate some fears about UEFI, there are three options: -Run UEFI boot and Legacy boot -Disable UEFI Boot -Disable Legacy Boot. I tried re-installing my OSes but I only had a "ribbon" style DVD burner in there and it didn't fit on my new board... when I tried re-installing Win7 via USB DVD Drive it kept prompting me for a driver which I ignored, kept my old install, and added my new license key... and everything was good with Windows. Afterwards I wanted to give Xubuntu 12.04 a spin so I tried to install that (again from my USB-DVD Burner), but this time it wouldn't load any type of graphic environment... some investigation is required, because the board has some graphic outputs as well as my video card, I'm assuming if I used the VGA output on the board I probably would have gotten a better graphical output. Ultimately I got lazy and kept my current Ubuntu install... so when it auto-detected new hardware it launched a partial ugrade and everything seems to be running smoothly there as well. Anyone else running Linux and UEFI have anything to add? -- Everything in moderation... Including Moderation --Oscar Wilde

I'll have to look into that, I assumed UEFI had the "secure boot" component built in. I thought secure boot was an option that you can turn off. Also, have you tried running Xubuntu 12.04 with legacy BIOS compatibility instead of UEFI? I think there are some driver differences between the two. I could be wrong, but I think the CD's BIOS bootloader is the usual isolinux which you should be able to recognize, and I think the UEFI bootloader is GRUB2. So that might be a way to know what you're using.

It offers you the option to keep both Legacy and UEFI, or to disable one or the other. said by grunze510: Also, have you tried running Xubuntu 12.04 with legacy BIOS compatibility instead of UEFI? I think there are some driver differences between the two. No dice with that... originally when I couldn't install Windows from the USB optical drive I tried this, and after not being able to install Windows, I tried Xubuntu, and once I launch the installer I get a garbled image and can't proceed further said by grunze510: I could be wrong, but I think the CD's BIOS bootloader is the usual isolinux which you should be able to recognize, and I think the UEFI bootloader is GRUB2. So that might be a way to know what you're using. I think the issue is the fact that I was using a USB attached DVD burner rather than an internal one, or USB key. -- Everything in moderation...

No, UEFI does not necessarily mean you have Secure Boot, just like BIOS doesn't necessarily mean you have overclocking. The only requirement for secure boot is if you want your ARM device "Windows 8 Certified." -- "Padre, nobody said war was fun now bowl!" - Sherman T Potter »maxolasersquad.com/ »maxolasersquad.blogspot.com »www.facebook.com/maxolasersquad

I have a FAT32 drive with the correct .efi files pointing to Grub2. Windows 7 is also installed. Windows 7 works fine with EFI but you must use GPT partition, MBR+EFI will not allow a Windows install. I have my boot time down to ~8 seconds on Gentoo using a native SystemD on a mechanical HDD. Arch (normal init) and Windows 7 boot in ~20 seconds. -- Show off that hardware: join Team Discovery and Team Helix

Seeing as I kept my previous installation, I was wondering if you could go into a bit more details about what GPT partition entails? (I'm sure I'll have to re-install in a couple of month anyway which is why I'm asking ) -- Everything in moderation... Including Moderation --Oscar Wilde

I believe gparted on the Ubuntu CD (live boot) has tools to convert as well. VERY DANGEROUS: this is low level HDD manipulation. Data backup can not be stressed enough to have before engaging. -- Show off that hardware: join Team Discovery and Team Helix

FWIW, I have three hard drives in the PC, one has Win 7 the other Ubuntu, and a 1.5 TB drive split down the middle with NTFS and BTRFS for extra storage of my Windows and Linux partitions respectively. So as long as that drive "lives" we're good. -- Everything in moderation... Including Moderation --Oscar Wilde
