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…

[image] 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).

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 :smiley:
