I have seen this happen multiple times and it is not an important thing but just wondering if anyone know why this is happening?
on the internet i have seen solutions of install in legacy mode, which i will not do and dissable secureboot which has been done
Is the bootable media in UEFI/GPT?
Is the hard drive formatted as GPT?
Is your 512M partition formatted and labeled as EFI file type?
Is the bootctl launched to /boot/efi ?
Somethings I would check that come to mind. I have not seen that before, though. If you’re using parted or gparted, try cfdisk and see if that works better for you.
Does it even boot in legacy mode?
Have you verifed the ISO to make sure its not corrupted?
Have you tried a different install media like a different USB stick?
not sure if it matters but i am making it bootable using dd

after that on bootup (these are just flipped on here for some reason)
It seems that when i use a manjaro iso on it i get this

i never get this far in the process, i am trying to boot the install CD
Your install CD is bad. Verify the install media from the grub menu.
thanks, that was the problem
Awesome, please mark the thread as solved if you feel your issue resolved 
I am having this exact same issue. I’m trying to boot the Fedora install media USB.
I have tried creating it with the Fedora Media Writer and dd. For the dd method I did
sudo dd if=Fedora-KDE-Live-x86_64-28-1.1.iso of=/dev/sdc bs=4M status=progress && sync
I have tried this with both standard Fedora and KDE Fedora, and for both I have checked the media from the boot menu and it shows fine. I even tried using two different USB drives.
Doing some research a popular fix is to make sure Secure Boot is disabled, but I don’t have any Secure Boot options in my UEFI.
