I am having trouble getting grub4dos to work on boot. I have grldr and menu.lst along with the Windows PE iso that I want to boot from and here is the menu.lst content. These files are all on a second partition F:

password 27
timeout = 30

title Windows XP Professional
hide (hd0,1)
find --set-root /ntldr
chainloader /ntldr

title Restore Menu
password 123456
unhide (hd0,1)
find --set-root /winpe_x86.iso
map /windowspe.iso (0xff) || map --mem /winpe_x86.iso (0xff)
map --hook
chainloader (0xff)

It would just continue on the Windows xp. How do I get the menu to appear?
