I am following this post and I am stuck at step 3 after verifying that it is UEFI I went ahead with the instructions. Running os-prober is giving me this error. and grub install is giving me another error. I looked around for solutions and found few but I haven’t tried them yet because I am not sure which drive to use them on. nvme0n1p7 is my linux partition in the fdisk output. When install EOS I went with the replace partition option.
