This won't work as it doesn't know what to load next. In case this info helps 
You need the XP (or NT) MBR plus the following files in the root of the boot 
disk: boot.ini, NTDETECT.COM, ntldr
These are in the root of any XP file system and can just be copied.
boot.ini contains which harddisk partition to boot and may need editing 
according to the partition structure on the disk.
This will then load from any bootable disk (floppy, USB, harddisk) and 
subsequently load the OS on that partition. On a non-encrypted filesystem.
You can make a bootable diskette (with that MBR) from within XP by formatting 
the diskette and checking the option to make it a system disk. However, I doubt 
this will work for USB sticks etc.
