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.
