This issue plagued me for the entirety of a week and having solved it on my own (because nothing else worked), I am finally at ease while still being puzzled.
So the fix is this: INSTALL USING THE NORMAL NON-UEFI BOOT
MY STORY – TL;DR
Now, let me explain:
I currently have Windows 10 installed on a MBR/BiOS Partition Table because Windows 10 will just not allow me to use a GPT/GUID Partition Table (I’ve tried instructions from… everywhere. Mainly the Arch Wiki). :/
I even went as far as installing just Antergos (UEFI Boot Install) expecting that things would work and I can just come back to a dual boot system after a few months. You guessed it! After I finished installing, Antergos would not boot giving me an error about there being no grub installation to boot from. I then went and did a fresh install of grub (using the same LiveUSB that performed the installtion) to the “supposed boot partition” and rebooted thinking “***Oh please! Easy fix.***”. Same damn error… -_-
This brought me to the the forums (Arch, Antergos & Manjaro) & Arch Wiki and I tried “every trick in the book” relevant to my machine. Nothing worked and after the 3rd day, I just said “Screw it! LinuxMint is where I’m going for now.”. Rinse… and repeat. - UEFI Boot on Live USB / DVD (I
tried wasted 2 DVDs) just does not work.
So finally, I installed Windows 10 and left 125 GBs of unallocated space for an Arch-based Distro to be installed when a fix comes out. After doing all my Windows updates, I decided to try again, this time I decided that I would, on a whim, try the non-UEFI / normal boot from Live USB option (using LinuxMint at the time). Voilà! Here I am typing this up (from my Manjaro KDE installation) to post on all the forums I am apart of.
NB: I’m noticing fixes are finally popping up on both Antergos & Manjaro threads for this issue. FINALLY
Add. NB: I do not think this is a MBR / GPT issue but that of a kernel issue. The reason I believe it is kernel-based is that during all this, I was able to install OpenSUSE 12.3 using the UEFI Boot mode from an old DVD I have had since that version of OpenSUSE was released (2013).
Add.++ NB: I tried the following Distros with UEFI Boot and failed: Antergos, Manjaro, LinuxMint & Apricity. The only Distro that worked OOTB was KaOSx.
PS: I don’t mind being corrected or even scrutinised for this post. This was “my fix” and I hope it works for everyone who have yet to find something that works.
