I've installed 12.04.2 on a OS-less Asus B85M-E (Intel Core i5-4430 [LGA1150]). When I boot, it freezes on a 'pink screen'. Alt-Ctrl-F1 has no output.

i have already reinstalled once. I read in many forum posts that some specific UEFI features cause problems with Ubuntu and GRUB and should be disabled before installation. So I disabled Fast Boot and Intel SRT, and then reinstalled. Secure boot was enabled when I installed a second time. Successful reinstallation, same freeze-up on reboot. I've since confirmed that Fast Boot, SRT and also Secure Boot are disabled. No change when booting.

Should I reinstall again? Should I use a later version of Ubuntu and the Linux kernel? Should I disable anything else?

Also, are there any guides on the UEFI BIOS menu for this Asus motherboard. It has so many options and many exotic names. The last machine I installed Ubuntu (12.04) on was a Celeron laptop, so this is all very fancy. It would be nice to know which options can or cannot be used with Linux.

Thanks for your help.

If you are installing on a disk with GPT partition table, you will need EFI-partition. Take a look at "Creating an EFI partition" in here:


You may also install boot loader on a different disk with legacy MBR partition table (e.g. USB flash drive).
