Multiboot USB w/ Basic PE Image
Best Answer KP13 , 01 April 2014 - 05:17 PM
AWESOME! It finally worked out! It was the case sensitivity that did it.
root (0xff)
chainloader /BOOTMGR
boot
So that seemed to work wonders. I appreciate all the help as always, you don't understand how annoying this problem has bugged me.
Thanks again,

So does the \sources folder have a boot.wim (i,e, WinPE loads as X: drive in RAM)?
If so, it should be easy to boot PE from the ISO.
title Boot PE
map /MyPE.iso (0xff)
map --hook
root (0xff)
chainloader /bootmgr
Make sure the ISO is contiguous (use WinContig or RMPrepUSB and Ctrl+F2)
Or just use Easy2Boot and copy the ISO files to the Easy2Boot USB drive?

The sources folder does have a boot.wim. I tried your code as well as running WinContig.
I get the following error after choosing it from the Grub4Dos menu:

can you go to the command prompt (type c)
and do
ls (0xff)/
what files do you see?
P.S. What version of grub4dos are you using (date and version is at top of screen)

Error 21: Selected disk does not exist
You will need to type the map commands in as well in the grub4dos console
map /MyPE.iso (0xff) map --hook ls (0xff)/
change name and path of ISO to match your ISO file.

Steve,
I mapped the .ISO using the command line and it does list the files in the base but I still can't boot to it. Do I have to type another line into the GRUB command line?

yes
chainloader /bootmgr
The error you got implied that /bootmgr does not exist. Is it listed when you type:
ls /
What files are listed?

so do any of these work?
root (0xff) chainloader /bootmgr boot
or
root (0xff) chainloader /BOOTMGR boot
work?

If the ISO is bootable then
title Boot PE map /MyPE.iso (0xff) map --hook rootnoverify (0xff) chainloader (0xff)
should work for most ISOs.
P.S. Have you tried Easy2Boot?
#15
Posted 01 April 2014 - 05:39 PM
Excellent, I'll have to try it out. I have not tested out Easy2Boot yet but I was planning on doing it in the near future!

Last question, is it possible to use this code as an appended config file for a Syslinux menu item?
