How to make a bootable USB flash drive of several Windows at once using UltraISO?

Question

Windows

UltraISO has an XpressBoot button, can I use it or use other means to make one bootable USB flash drive from 2 iso images?

Answer 1

I see no reason to do this necessarily using UltraISO. In order to install any of the current Windows from one flash drive, you don’t have to fool yourself, but simply take a ready-made MultiBoot assembly - it, in addition to clean (without any additives, I personally guarantee it, since I have been using it for a long time) WinXP, 7 and 8.1 distributions (all versions - x86 and x64, from Home to Professional and Extended, selection in the input menu), also contains a tool-recovery package of 2k10 utilities, so it will come in handy not only for installing Windows, but also in a thousand other cases.
There, of course, you need to understand when creating it, since the author provided for different options (on DVD, 8 and 16 GB), but personally I succeeded from the first reading of the instructions (very detailed and intelligible).
