I am have a fully updated Arch Linux system that was running fine. Last night I tried to setup autofs per instructions on the Arch wiki, but upon restart there was no boot menu and only a GRUB error message saying "Error 15".
(1) Using Ext2explore in Windows, I can see the following partition structure:
(2) Using fdisk in an ArchLinux live cd, I can see this:
(3) I tried to do "fdisk /dev/sda/" then the commands x, f, w to correct error, but fdisk says my partitions' "ordering is correct already"
(4) Using the root and setup commands in the GRUB shell also ended in failure (it tells me it can't find GRUB files, /boot/grub/, etc. etc.). Specifically, I tried "root (hd0,1)", then "setup (hd0)", (also hd0,0, hd0,2, etc.), all failed.
Is there any hope of restoring my system? Thanks for your help.
P.S. here is my menu.lst, which can be seen in Ext2explore:

I tried the solution provided in the first answer, but failed with the following output:
Also notice that menu.lst is not there, even though it appeared when I examined the partition in Ext2explore.
Also, here are the contents of /etc/fstab:

Boot from your ArchLinux live cd again and in a command prompt as root run the exact following.
Depending on what you did trying to setup autofs, you might want to check that
/etc/fstab
or/boot/grub/menu.lst
files are valid while you are chrooted in your system (aftermount /proc
above).There is also one more (shorter) way this can be done. Not sure if it is possible with the archlinux live cd, but probably is.
