Macrium Rescue Media for 2 Computers on same USB

I routinely use just the one Reflect recovery usb to both back up and restore multiple laptops of various vintages, some UEFI, others Legacy: Dell (3), Toshiba (2), Acer, Lenovo and Samsung. I haven't yet found one that it doesn't work for. At least, for a local backup/restore to/from a usb HDD. I haven't tried networking, that may require specific drivers not included by default.

Yes , ONE (!) backup-CD for several PCs , works awsome on three machines ............!

We have three (3) laptops in our house: one Windows Vista, one Windows 7 and one Windows 10.

So, from what I'm reading here.... I might be able to use one Macrium Reflect Rescue USB (or CD) to Image or Restore all three three laptops. Is that correct?

On which laptop should the Macrium Reflect Rescue USB (or CD) be created? Vista, Win 7 or Win 10?

And, which WinPE version should be used when the Macrium Reflect Rescue media is created? WinPE 5, WinPE 10 or other?
I don't think WinPE 10 is compatible with Windows Vista, is it?
Which WinPE version is compatible with all 3 operating systems: Vista, Win 7, and Win 10?

Thanks for your help.

I don't think WinPE 10 is compatible with Windows Vista, is it?

Booted media isn't reliant on the installed os. If it is a very very old machine, it might have trouble loading win10 pe
