Hello.

I am trying to set up an USB flash drive, based on Grub4dos, with two options to choose from: boot to MS-DOS and boot to WinXP PE.

 

Now I have my UFD with the Grub4dos menu, MS-DOS booting works properly, I've tried making the ISO of WinXP PE, but it didn't really work, as it gave a bluescreen (used BartPE). Also, I would prefer if it was a clean XP PE, with a possibility of adding my own programs. 

 

I have an original WinXP Home Premium CD, the UFD would be used as a fixing/scanning flash drive.

I've tried making the ISO of WinXP PE, but it didn't really work, as it gave a bluescreen (used BartPE).

Add a appropiate driver.
 

title mem Loading F6 firadisk and BartPE.ISO
ls /BartPE/BartPE.ISO || find --set-root /BartPE/BartPE.ISO
map --mem /BartPE/FiraDisk.IMA (fd0)
map --mem /BartPE/BartPE.ISO (0xFF)
map --hook
chainloader (0xFF)/I386/SETUPLDR.BIN

Okay now, I've gone another way, I have an ISO of WinXP, and have it connected to Grub4DOS to boot it, but there's another problem now: 

 

I need to be able to boot MS-DOS from the same menu: I have partitioned the flash drive, and now have Grub4DOS and WinXP iso on (hd0,0) and DOS (not an image) on (hd0,1). I am able to run DOS with 

title MS-DOS
root (hd0,1)
chainloader (hd0,1)/io.sys

but it asks for a command interpreter path after booting. Also, DOS sees the Grub4DOS partition as C:, but DOS is installed on D:. 

I need a way to set the root for DOS to (hd0,1), also, will it automatically detect COMMAND.COM?

 

tl;dr

need Grub4DOS menu.lst code for setting root for DOS.

I need to be able to boot MS-DOS from the same menu:

Sorry, I'be no experience with grub4dos DOS boot.
Hopefully another can help.

Spaps,

please try describing your COMPLETE current setup and what is your actual "final" goal, DOS wants to be booted from the (first) active partition (i.e. "C:\") see also:

http://www.msfn.org/...-compatibility/

most probably (it depends from a number of factors) it may be enough to set the (hd0,1) as the Active partition (permanently) or to include a set or unset command for it in each of your menu.lst entries, consider how if you are using the grub4dos "installed" (to the MBR+a few hidden sectors) there is no need for the partition containing grub4dos to be active, the grldr will be found anyway.
