That is your choice, but you will have the same UEFI/CSM conflict-potential with whatever Linux you choose to use. That also goes for an upgrade from W8 to W8.1 if that is relevant (you haven’t said which version you have, but since you obviously start with a blank SSD, I would guess that you have W8.1, making the upgrade-part irrelevant). In addition, you need to adjust W8 for it to be able to coexist with another OS.
All of this will be needed with no regard to the Linux distribution you choose. Unfortunately, that also means that you have to do some sort of knowledge-gathering in order to succeed with W8/Linux dual-boot.
That’s a very good starting point for a dual-boot solution! But your installing Windows 8(.1?) from DVD also allow more choices than vendor preinstalls (which are more predictable due to Microsoft’s Windows licensing terms). So, to be able to help out, we need to understand your starting point better. Please see below.
That is the preferred and generally recommended installation medium. Some do transfer it to USB, which will install a little faster, but I have always used the DVD medium.
We need to establish whether you installed W8 under UEFI or CSM, and (if it was UEFI) whether SecureBoot was enabled or not.
Since Windows does not support MBR from UEFI and similarly, doesn’t support GPT from CSM mode, we can use your disk’s partitioning setup as an indicator of whether you used UEFI or CSM when installing W8. Here is one way of doing that:
From Windows 8 Desktop:
<WindowsKey>-X —> Command Prompt (Admin)
diskpart
list disk
exit
exit
Example from one of my test-installations (not a dual-boot setup, it is W8.1 under VMWare Workstation 10 - W8 and W8.1 are similar):
Microsoft DiskPart version 6.3.9600
Copyright (C) 1999-2013 Microsoft Corporation.
On computer: W81PRO64VM
DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 50 GB 15 GB *
DISKPART> exit
Leaving DiskPart...
C:\Windows\system32>exit
An asterisk in the GPT-column indicates that you are running GPT.
-
If that is so in your case, you installed W8 in UEFI mode.
-
If not, you installed W8 in CSM mode.
-
If you do not have UEFI/GPT, you do not have SecureBoot either.
-
If you do have UEFI/GPT, you should enter your BIOS/UEFI setup and look for a SecureBoot alternative - and see whether it is enabled or not.
[LIST]
-
If it is enabled, then fine.
-
If disabled, enable it, save/exit the UEFI/BIOS configuration menu, and try booting W8.
[LIST]
-
If it succeeds, you installed W8 having SecureBoot enabled.
-
If it does not succeed, you need to disable SecureBoot to get W8 going again (or reinstall W8 with SecureBoot enabled).
[/LIST]
[/LIST]
Linux should be installed using the same mode as you did W8 (still, this will be the same no matter what Linux you choose).
Also, with no regard to Linux of choice (or another, parallel Windows-installation, for that matter), you should at minimum make sure to disable Windows 8 Fast-start as I explain in the how-to. See here: https://forums.opensuse.org/showthread.php/487837-How-to-Dual-boot-(preinstalled)-Windows-8-and-Linux-UEFI-etc#4, the “Preparing Windows 8 for dual-booting”, item 4). I will also think that you are interested in Part 6 of the how-to.
CSM installed W8:
My Linux/W8 dual-boot how-to does not cover CSM installation. However, if you did follow my minimum recommendations above, you should now be fine to commence installing (any) Linux according to its installation instructions. openSUSE isn’t particularly complex in that regard.
UEFI/GPT-installed W8:
If you do have UEFI/GPT installation, you can go ahead as I advise in my previous posting in this thread, but since you already did limit W8’s disk space, you obviously should disregard the part about shrinking W8 disk space. Also, openSUSE 13.1 detects SecureBoot installation (or not) automatically, so you do not need to do anything particular in that regard. Just install Linux using the same SecureBoot status as you did W8.
Later on (if you installed using SecureBoot), you can enable/disable SecureBoot as you wish for both OS-es, and any setting will work for either OS. Again, this will be common to any Linux.
Note:
Not all Linux-es do support SecureBoot yet, though, but openSUSE does - among others.
Good luck with your installation and choice of Linux!
