USBFastBoot 1.0
SBFastBoot is a small utility that helps you to quickly test your bootable USBs or disk images.
In fact, currently it works for drives (USB and HDD), ISO (cd image) and IMG (floppy image).
It simply adds a context menu item 'Boot on QEMU' that you can click to... boot on QEMU.
It requires Windows XP and the .NET Framework. It also requires administrator privileges to install it on your computer.
