Multiple VHD on a single USB

[admin]

When I use WinToUSB and create a WinToGo USB drive from a Windows 10 ISO for example, I see that a VHD file is created on the USB drive from which the OS boots. Now my question is, whether we can add a few more VHDs to that same USB drive, so that we can choose which of the VHDs I can boot up from, at startup ?

For example, I want to create a bootable WinToGo USB of Windows 10 using WinToUSB. SO I get an USB containing a VHD file.

Now I can create another such similar WinToGo on a different USB drive, That drive will also contain another VHD file.

Now, I want to add that second VHD also to the SAME [first] USB that WinToGo that I made, and I want the bootloader to ask me at startup as to what VHD I want to boot from...

Can you please tell me how I can do this ?

EDIT:

I have already seen this thread... Hoping to see more clearer steps on how exactly it can be done .. Thank you

If you can assign a letter to the system partition on the Windows To Go drive, then you can create a multiple-boot Windows To Go drive with the following steps:

1. Create a Windows To Go drive using WinToUSB
2. Copy the VHD file which you want to add to the Windows To Go drive created in step 1
3. Attach the VHD file in Windows built-in Disk Management
4. Assign a drive letter to the boot partition on the VHD disk (In my case F: is the drive letter for the mounted VHD file.)
4. Use the following command to add a boot entry to the Windows To Go drive:
    Bcdboot.exe F:\Windows /s E: /f ALL /v (E: is the system partition on the USB drive, F: is the mounted VHD file)

You can add multiple VHD files to the USB drive using this method.
