Windows 8 dual boot ubuntu 12.10 on 2 ssd drives

Hello all. I am new to the forums and have been having a very annoying issue as of late. I currently have a machine installed with Windows 8 pro 64 bit installed on one Samsung 840 pro SSD. Works great. I recently added a second Crucial m4 SSD and would like to install Linux on it... I am having major issues doing so mainly because of UEFI... and when installing Linux it does not see Windows 8 installed on any drive therefore making it rather difficult to install both OSes. Any advice would be wonderful! I have searched Google quite a bit only to find the same issues but non relating to ssd drives. Thanks in advance!

Welcome to EightForums.


First you will need to DISABLE Secure Boot.

Reset BIOS to default, and reboot to BIOS make sure Secure Boot is disabled.
Make sure CSM is ENABLED, & set to UEFI boot.
NOTE: Check your manufacturer's uEFI BIOS manual for settings.
Secure boot: technical types spreading half-baked information

Linux distributions are making slow progress on implementing measures to ensure that their images available for download are bootable on hardware that has secure boot turned on.


Secure boot is a feature of the UEFI, the Unified Extensible Firmware Interface, a replacement for the BIOS.

Microsoft has implemented this feature on hardware certified for Windows 8 in a way that requires the exchange of cryptographic keys; since the company controls the key-signing authority, anyone who wants to create a bootable medium has to necessarily obtain a key from Redmond.

Misinformation is rife about secure boot, simply because people confuse UEFI with secure boot and think that support for the former means support for the latter. Many so-called technical types are as guilty as others of spreading wrong information.

“Microsoft's real aim is to kill the aftermarket in used computers that have Win 8 installed by not allowing you to install something other than Windows”
Microsoft could just have refused to sign UEFI bootloaders. They didn't. That doesn't really fit in with what you're claiming.

Welcome to the forums.

Non relating to SSD drives you say? True. This seems to be a UEFI problem.

If you'd had two HDD's instead it will mostly result in the same problem. (Are people experiencing problems with 2 SSD's only?)

In the end, Ubuntu will have to detect Windows or otherwise you'll have to try the Wubi installer to install Ubuntu form within Windows: then the Win8 boot-loader will take care instead of GRUB. The second option seems safer, by the fact we're dealing with UEFI.

It's better to test things like this in a VM and see if the two OSes will detect each other before performing host operations, just to be sure.

Yes!
I always forget the Secure Boot.

In the future we'll probably be able to leave it on at least for Fedora installs if they'll get MS certificates. Not sure about Ubuntu.

DISABLE Secure Boot will probably be it.

Keep in mind that dualboots with Win8 performing hybrid boot (hyberboot=enabled) can have some undesired effects.
