Backstory: I backed up windows 10 and restarted my laptop on a boot drive loaded with the Arch linux iso that was created with Rufus. I entered cfdisk and deleted all partitions except for the "EFI System" and the "Lenovo boot partition" partitions. When I tried to install the base packages with pacstrap, it told me that the partition block size was too small so I expanded the EFI System partition upwards (There was a gigabyte of extra space and I thought that might help). It didn't work and a while later I tried remounting my linux file system (/dev/sda4) and it worked. I skipped over a bunch of other steps I took, but I thought these would be most relevant.
Whenever I try to run the command to install grub:
grub-install --target=x86_64-efi --efi-directory=/dev/sda1 --bootloader=arch_grub
It just outputs:
Installing for x86_64-efi platform. grub-install: error: cannot read `/dev': Is a directory.
Even though the path I'm giving it is the efi partition (/dev/sda1). I've tried giving it /boot for the efi directory parameter, but if I try that, it just outputs:
Installing for x86_64-efi platform. grub-install: error: /boot doesn't look like an EFI partition.
I'm fairly new to these 'do-it-yourself' type of distributions and I would appreciate all the feedback I can get, thanks!
