Hi,

I have a OEM Windows 8 Sony Vaio E-series. Tried dual booting Linux Secure Remix (Ubuntu 12.10) with EFI having followed the instructions here: https://help.ubuntu.com/community/UEFI

Disabled Secure-boot.

No option in BIOS to disable fast-boot.

Ran Boot-Repair with recommended conditions and restarted.

I'm trying to dual boot Ubuntu 12.04 (or 12.10) with Windows 8 on a new Sony Vaio, but have run into some problems :)

Specifically, my problems seem to come from choosing UEFI or Legacy as the Bootmode in the BIOS.

Here is what I have found so far:

Windows 8 needs to boot using UEFI, and doesn't work in Legacy mode Ubuntu (both 12.04 and 12.10) needs to boot using Legacy, and won't boot (at l

I've recently purchased a Lenovo T430, and sadly when configuring it, I forgot all about the Linux UEFI Fiasco, and kept the default option of pre-installing Windows 8.

I'm able to disable secure-boot, but what I would like to know is whether I need to install Ubuntu in UEFI or Legacy Mode.

I just brought a new Toshiba Satallite M840 with pre-loaded Windows 8.

I've had a nightmare of a time installing Arch with UEFI (Z77e-itx). At first I couldn't get Arch to boot after a few installs, then I managed to get a working system but my windows hard drive somehow managed to lose its boot-loader.

GRUB2 UEFI BIOS l 8 weeks 6 days ago

I'm using a M5A97 R2.0 (so very very similar AFAICT looking at the Asus website). It will boot UEFI or MBR and you can switch off SecureBoot in the BIOS. You may need to get the latest BIOS from Asus to get the SecureBoot options. I'm using it in UEFI mode without SecureBoot and it's been fine.

This is a new computer that can only boot in UEFI mode. ( or at least I do not know how to switch to normal BIOS mode). I am not able to install ubuntu 12.04.1 or ubuntu 12.10 using the livecd. The live CD does not boot properly. I get error message with subsequent kernel panic. It came with windows 7 preinstalled. bcdedit indicated that windows in UEFI mode.

[ubuntu] Install with UEFI? 27 weeks 5 days ago

I have an X-series Asus laptop which I just bough about a month ago. I want to dualboot Ubuntu - Windows.

I can easily access LiveUSB with both UEFI enabled and disabled. I heard that there were problems with UEFI, so I disabled it. After I've installed the system I couldn't access it.

From LinuxBSDos.com.Dual-booting Windows 8 and a Linux distribution in UEFI or EFI-compatible mode can be a very frustrating and unpredictable adventure. You just never know how the system will boot or whether it will even boot at all. I have a computer that I built (assembled) using a motherboard with UEFI firmware. By default, it boots in Legacy mode.
