Windows: Can't decide whether you should commit your spare thumb
drive to Windows recovery, Ubuntu, or some other live-booting OS? Run
MultiBootISOs on your USB drive, and you won't have to choose—you'll
just choose between them at start-up.
The folks at
PenDriveLinux.com have created a Windows tool for creating what is
basically a GRUB multi-OS bootloader on your USB drive, along with a
nice long list of systems that work with it. All you have to do is grab
an ISO file of the system you're adding to your drive, then drop the
whole ISO file onto the drive (occasionally with special instructions).
There's all the usual Linux cohorts—Ubuntu, Fedora, openSUSE, etc.—but
also some great rescue tools and utilities, like the GParted partition
disc, Ophcrack password reset, and virus scanners. You could even load a
Windows 7 installation DVD onto your thumb drive, if you had the room.
tried out PenDriveLinux with Damn Small Linux, Ubuntu, and Gparted on
one USB drive, and it worked like a charm. If you find trouble booting
up, check out the page text for tips on creating a Master Boot Record on
your thumb drive, and fixing other problems that can crop up.
MultiBootISOs is a free download for Windows systems, and we're definitely thinking about going back Boot Multiple ISO from USB (MultiBoot USB)
