You should first download DOStoWXP (a tool that directly boots Windows XP from DOS), download here:
http://www.msdos.tk/show.php?id=78
Then put all the files from DOStoWXP in the root directory of drive C
Set the default boot system to MS-DOS 7.1
That is, in boot.ini set default= to default=C:\bootsect.dos
Or add a space after multi(0)disk(0)rdisk(0)partition(1)\Windows="Microsoft Windows XP Professional", then add /WIN95DOS (I haven't tried this method either; saw it online, use with caution!)
Then add this line at the end of autoexec.bat in DOS 7.1:
if exist ghost.bat ghost.bat else dostowxp
That will do it. Basically, you're just using DOS 7.1 as the OS Loader.
