Bootloader installation failure error everytime I try to install EnOS

[DumbCat]

Everything passes successfully but at the end of the installation it says failure and says that the bootloader (grub) could not successfully install. I already have windows 11 installed on my system. I shrunk the partition and created ~99 gb of unallocated space for EnOS to replace upon installation. Installing it the first time had the same error (error code 1, grub-install), i tried deleting that partition and wiping it for EnOS to try again, but to no avail.

I have posted the installation logs here on termbin. Any help is appreciated!

EDIT: Just to clarify. Secure boot is disabled. It is a UEFI system to the best of my knowledge (its a fairly new system)
FURTHER UPDATE:
looking through similar posts on this error “stdout:Installing for x86_64-efi platform.
grub-install: error: cannot copy /boot/grub/x86_64-efi/core.efi' to /boot/efi/EFI/endeavouros/grubx64.efi’: No space left on device.” (which i also have), some people tried reflashing their BIOS? is that really the only option i have left because i do not want to fiddle with that thing ;-;

Well maybe you are refering to the below linked topic, there is also a advice given to create a new efi partition for the bootloader in this topic , maybe this might help.

Grub bootloader install fail

Hello, I’ve been tying to install endeavouros on my asus tuf dash f15 laptop, but any time i do i keep getting the same error with the installation of the grub bootloader "Could not prepare Boot variable: No space left on device grub-install: error: efibootmgr failed to register the boot entry: Input/output error. 2025-02-03 - 21:04:44 [2]: WARNING: [PYTHON JOB]: "Command 'grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=endeavouros --force' returned non-zero exit stat…

Could you walk me through the steps of creating a new one? Is there any setup that i’ll need to do, also what size? I dont wanna brick my windows install :p.

Have to checked to make sure your EFI isn’t full?

Also, did you disable “Fast Startup” within Windows?(This is not “Fast Boot” in your BIOS but a setting in Windows) If not, your ESP may be marked dirty as Windows and it will not be writable in Linux.

Sorry to say but after checking the log you posted, EFI is full:

100M EFI strikes again

During install you can see the small “box” at the bottom and click on the down arrow where it says efi system partition , click on the arrow and choose create a new one (or something like that).

Yikes.

Okay, let me go into the live iso again and see what options show up. I will update as soon as possible

EDIT: Found the ‘new’ option. It automatically set the necessary things up. I’ll let it run and see what comes out of it. Took a backup just in case :d.

Worked! Thanks a lot for all of your messages
