Hi all,
So far, my attempt to install Arch Linux on a UEFI system is a total facepalm moment. The problem is in booting post-install.
So, first, does anyone have actual--and successful--experience installing Arch on a UEFI system? Yes, I went to the Arch Wiki, which initially pointed me at GummiBoot. There are actually two sets of instructions, one given where I looked first, for the UEFI entry, and another under the entry for GummiBoot. Neither succeeds, but I wound up following the latter set of instructions (and cleaning up extra entries with efibootmgr, which fortunately makes this relatively easy).
GummiBoot says it can't find /vmlinuz-linux. I tried modifying the configuration to say /boot/vmlinuz-linux, but no joy. Apparently, I'm really supposed to copy this file and the initrd image to the EFI partition, but nobody says where in the EFI partition, so I have no idea.
I also tried following the instructions for grub-efi. I'm just mystified. I managed to install the right package, but from there I just wasn't understanding a thing. I've been using linux since 1999 so this shouldn't be so completely mystifying.
I tried installing rEFInd (from sourceforge). As near as I can tell, it does indeed detect all the possible boot options on the system. But when I try booting the Arch installation, it says it can't find the root partition. It also detects the GummiBoot option, but that leads the same place as before. Finally, it detects the Windows option, which I hope still works (unfortunately I do need this).
I guess getting something that just works--like it did with BIOS systems--is not in the cards. What do I do now?
Thanks!

Make sure the EFI System Partition is mounted at /boot. Gummiboot expects this: The /vmlinuz-linux path is relative to the ESP. With the ESP at /boot, pacman automatically installs the kernels where they need to be, and no ugly copying hacks are necessary.
