How to run Windows 7 install from ISO using GRUB4DOS?

Question

ISO

Good afternoon! tell me how to run the installation of Windows 7 from an ISO image using GRUB4DOS. I used what is written here forum.oszone.net/post-2136973-5233.html
title Windows Vista or later
map --mem (md)+4 (9)
map /Boot/Windows.iso (0xff)
map (hd0) ( hd1)
map (hd1) (hd0)
map --rehook
write (9) [FiraDisk]\nStartOptions=cdrom,vmem=find:/Boot/Windows.iso;\n\0
chainloader (0xff)
and here
greenflash.su/ forum/5-1330-1
debug off
set MYISO=win7.iso
dd if=()/firadisk/au.xml of=()/AutoUnattend.xml
map --mem (md)0x800+4 (99)
map /ISO /%MYISO% (0xff)
map (hd0) (hd1)
map (hd1) (hd0)
map --hook
write (99) [FiraDisk]\nStartOptions=cdrom,vmem=find:/ISO/%MYISO%;\n\0
chainloader (0xff)/BOOTMGR || chainloader (0xff)
does not see the drive all the time. I tried it manually, at the moment map --mem (md) 0x800+4 (99) an error occurs, I can’t overcome it in any way.
