    I know that you can use this to make a bootable usb for multiple linux distros. But can you add both windows and linux to the bootable drive?

    I try to make Windows 7, 8 and 10 but it seems just overwrite (or maybe skipping) the old 7 installer, so when I boot into windows 8 it always boot into windows 7. Did you know how to make them works together?

    From YUMI's website: "Currently YUMI will only allow you to boot from 'ONE' Windows Vista/7/8 Installation. For example you can't have Windows 7 and a Windows 8 installer on the same YUMI drive."

    You have to add images with Yumi, Personally I just use a bunch of 8gb cheap thumb drives and now use a program called Rufus to make these

    Hi rizkiandrianto, I hope you've solved this problem by now, but if not (and for others who may read this with the same issue) the solution is pretty simple. If both of the operating systems are installed in the same BIOS mode (UEFI, Legacy, CSM, etc.) then all you'll need to do is boot one of the copied of windows, then in the windows search (formerly known as the "run" box) type in "msconfig". From here you can click the "Boot" tab, and select your settings (default operating system, how much time, if any, to allow the user to choose which OS to boot into after turning on the machine, etc.)

    I hope this helps everyone.

    Really cool; I've done this with Linux countless amounts of time, but I had no idea the same could be done for Windows.

    Most netbooks don't have dvd-roms in them and most servers now don't come with dvd-roms as they are an add on option. So use Yumi (or a different piece of software) to make a boot USB thumb drive to install windows or another OS
