View Full Version : Dual Boot setup - Can't see windows 8.1 install

February 2nd, 2015, 05:07 PM
I've been trying for a few days to get a dual boot Windows 8 / Ubuntu setup running but nothing I seem to do will let me see the host OS when trying to install linux along windows 8.

I have windows 8 installed on my HDD
Disabled Fast Boot in the OS
Followed directions to disable UEFI Secure Boot options.

I have a MSI Z77A-G43 motherboard so when I first entered the BIOS to check on the secure boot options I had to find the feature under the "Windows 8 Features" which was already set to disabled:

note that "Windows 8 Feature" is disabled.

I tried to run the install but was unable to detect the host OS again so I went back into BIOS to confirm that it was disabled:

enabled windows 8 features - confirmed all fast boot options were off and confirmed secure boot is off -http://imgur.com/57nG7LE (http://i.imgur.com/57nG7LE.jpg) [3] - Secure Boot Disabled

At this point if I leave the "Windows 8 features" option set to Enabled even though all suboptions are disabled I receive the following error:

If the Windows 8 Feature are all disabled then the secure boot option should also be disabled and the OS should be visible correct? When I explicitly try to disable each sub-option I am unable to boot my computer because of a weird graphics card drive issue?
Any suggestions?

I have not seen a UEFI/BIOS complain about the graphic card.
UEFI, Windows on SSD, Ubuntu on HD ASRock Z77 Pro4 motherboard

But newest Widows is not enabling TPM, do you have any settings for that?
Some UEFI also have TPM
UEFI secure boot doesn't have anything to do with a TPM.
Microsoft has announced that from January 1, 2015 all computers will have to be equipped with a TPM 2.0 module in order to pass Windows 8.1 hardware certification.
Re: certificate to verify signature of Ubuntu kernel

And nVidia has drivers with some cards with some security that is not yet in the open source driver, so you have to have the nVidia driver. Best to install from Ubuntu repository unless a very new Maxwell card.

You also have fast boot settings in Windows as well as UEFI.

Fast Startup off/hibernation
Fast boot is hidden.
If issues you may need these?
Control Panel -> Power icon -> Choose what power buttons do -> Change settings that are currently unavaliable, make sure fast startup is unchecked
powercfg /h off

Do you have the latest verion update for UEFI from MSI?
