Is it possible to have Windows 11 + Windows 10 (WinToUSB) on the same external SSD?
I'm using this software:
WinToUSB (also called Windows To USB) is the best free Windows To Go Creator that allows you to install & run Windows on USB drive or Thunderbolt drive as portable Windows.
www.easyuefi.com
Don't bother with that software -- can be done 100% in bog standard Windows.
The best and easiest (and quickest - and FREE) software is Windows itself !!! in this case,
Simply have vhdx files ---
on the external disk -- one partition efi (size 100 formatted, rest of disk as one bog standard ntfs partition
Now on the external disk create your vhdx files for W10 and W11 (diskpart -> select disk xxxx, create vdisk file=xxxx.vhdx maximum {size you want --W11 must be 64 GB min} type - fixed -- attach vdisk etc
Install the windows system(s) by DISM /Apply-Image etc
Now this is the trick for getting the "WintoGo" bit
on the external drive look for the efi partition of 100mb -- assign it say as S:
For each windows system do this in turn, --you need to boot either any iso / macrium (PE stand alone version, not the RE version) into command line
Assume the windows install is on vol W now install the bootloader to the EFI partition (the boot partition the computer will use - not to be confused with the "C" partition of Windows.)
cd w:\windows\system32
w:
bcdboot w:\windows /s S: /f UEFI
now boot your external usb drive -- you should get the standard Blue boot menu with a choice of W10/W11 and you can change the default etc.
Have fun :
