I created VHD with WIN7X64.
Installed Firadisk driver and successfully booted from mapping to ram drive.
But when I tried to do it from disk mapping I got a 7B

What I tried at first was something simple:

map /WIN7.VHD (hd0)

map --hook

chainloader /bootmgr


Ended with 7B

Then I decided that maybe firadisk can't see the mapped drive and used the folowing:

map --mem (md)0x800+4 (99)

map --hook

write (99) [FiraDisk]\nStartOptions=disk,vmem=find:/WIN7.VHD;\n\0



map /WIN7.VHD (hd0)

map --hook

chainloader /bootmgr


But that ended also in 7B

It is possible as shown here

You can try VHD_W7_Compact.exe
In any case the menu.lst that I used is different, here some AutoIt3 code that I used ....
and which contains additionally map --heads=2 --sectors-per-track=18
and ,bootn0 and rootnoverify (hd0,0)


FileWriteLine($TargetDrive & "menu.lst",@CRLF & "title Port " & $entry_image_file & " - FiraDisk  FILEDISK - " & $PSize)

FileWriteLine($TargetDrive & "menu.lst", "map --heads=2 --sectors-per-track=18 --mem (md)0x800+4 (99)")

FileWriteLine($TargetDrive & "menu.lst", "map /" & $entry_image_file & " (hd0)")

FileWriteLine($TargetDrive & "menu.lst", "map --hook")

FileWriteLine($TargetDrive & "menu.lst", "write (99) [FiraDisk]nStartOptions=disk,vmem=find:/" & $entry_image_file & ",boot;n0")

FileWriteLine($TargetDrive & "menu.lst", "rootnoverify (hd0,0)")

FileWriteLine($TargetDrive & "menu.lst", "chainloader /bootmgr")

FileWriteLine($TargetDrive & "menu.lst", "map --status")

FileWriteLine($TargetDrive & "menu.lst", "pause Press any key . . .")

:cheers:
