So I have this external Bootcamp that is a portable Windows, however, I fear that the installed drivers on it would not work on other computers, thus making it not boot on other computers that is meant for Windows. Is there a way to avoid this issue, at least to passby the login stage?
A proper BootCamp install on the drive requires MacOS. So when you boot up under it using the MacOS partition you can upgrade the MacOS as you normally do for either updates and/or upgrades. The MacOS upgrade or install will update the needed drivers. Nothing to fear here.
