Success. The dual boot is done and ready for download

We now have a working solution for enabling xboxhdm2 & FreeDOS HDD tools on 1 USB stick.
Credit is owed to many others - I have just repackaged what's available. Notable thanks go to:
-
fuwi for his great work on multibooting.
- Anny for developing the above idea into a working solution

- Ldotsfan for advice & help.
The multiboot is not difficult to achieve - and we have minimised the amount of steps needed.
** However please be advised - this is generally for advanced users - you could mess things up if you dont follow the instructions.1. Follow the instructions on
Page 1 for getting the normal xboxhdm2 set up files (remember you need to supply your own linux.iso & eeprom).
2. Make sure you also download FreeDOSAddOnNew.zip (<1mb)
3. Download
grub4dos gui4.
Do not (Run "bootinst.bat" from the "boot" folder of flash drive) as in the original posting (to create a bootable USB stick). We'll sort that later.
5. Extract all files as instructed and extract FreeDOSAddOnNew.zip to root of USB stick.
You should therefore have in the root of your drive something similar to screenshot below

Now using the file you downloaded in step 3 - follow these
instructions to install the MBR to get your USB drive to multiboot
(**make sure you select the right drive to install the MBR to. Get it wrong and you could brick your PC!)That's it! Reboot and if all gone well, you should see the grub4dos boot screen. Incidentally, there are several txt files contained within the FreeDOSAddOnNew.zip file (hdparm, DOS un/locking instructions) that may help you.
For the record:
DOS un/locking instructions can be found on

hdparm guidance can be found on

Good luck
