Issues installing grub on EFI system [Solved]

My system is UEFI/GPT.  I have mounted my EFI system partition, sdb2, (which also boots windows) to /boot.  mount /dev/sdb2 /boot
Then I entered the command listed here https://wiki.archlinux.org/index.php/GR … all_method, replacing $esp with /boot.
The output for this command/script was default, except for a line at the end that said

grub-install: error: /boot doesn't look like an EFI partition.

I tried the script again, this time replacing $esp with /boot/efi.
The output this time was this:

grub-install: error: /boot/efi doesn't look like an EFI partition.

.
Is there something I'm neglecting to do?  I'm primarily going off the wiki, but it didn't tell me to mount /dev/sdb2(my EFI partition) to /boot.  I did that because of info through a google.  I'm certain that sdb2 is my EFI system partition.
I appreciate any helpful advice you can give me.  I really love the idea of arch.  Its what I thought linux would be when I first installed ubuntu almost a year ago.
Thanks
(It is possible that this should be posted to Newbie Corner.  If so, I apologize.

Re: Issues installing grub on EFI system [Solved]

Where during the installation stage did you use that mount command?

I believe you should mount the EFI partition before you pacstrap and arch-chroot, ie...

mkdir /mnt/boot
mount /dev/sdb2 /mnt/boot

Edit - Or do you already have an installed system and you're just trying to change bootloader?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Load the Arch live ISO, mount all your partitions, use `arch-chroot` and post the output of:

# parted -l
lsblk

You can use a pastebin client to generate a URL which can be posted here.

Re: Issues installing grub on EFI system [Solved]

Thanks for your assistance.  It seems my problem was having 2 partitions mounted to /boot.  My system EFI partition, and the boot partition I created.
I figured out that since I was using the EFI partition for grub, I didnt need a separate boot partition at all.  Grub was trying to use my ext4 boot partition as the EFI partition.  It's working now.
Also, thanks for the advice about pastebin clients.
