Bootable Pendrive

yes it is.

there are several ways to do it. You can sue Bart PE, win2flash, grub4dos and other similar tools.

but what is your need? You want to make a live version to use just like live version of linux distros or you just want to boot them from USB to install/format ?

You can search online for making bootable pendrives using the software mentioned above.
or as an alternative you check the post <a href="https://babbleona.blogspot.com/2010/02/how-to-install-windows-from-usb-drive.html" target="_blank" rel="nofollow noopener noreferrer">Technorama Blog: How to install Windows from USB Drive</a> that I had written on my blog. I used Win2Flash which is by far the easiest and simplest way to make a bootable USB drive
