How do you boot linux from a flash drive?

I am looking for the best linux os distro that could boot straight from my flash drive.





Something like knoppix but for flash.





Another question, with that, can you access the hard drive and store information? Like to fix a windows machine?

To intall to USB drive:


First, boot up your computer from the DSL livecd, frugal, or USB-frugal. Note that it is not possible to do a USB install, or any other kind of install from a DSL Embedded system.





In the Fluxbox menu, go Apps %26gt;%26gt; Tools %26gt;%26gt; Install to USB Pendrive and choose either USB-ZIP emulation or USB-HDD emulation, depending on what is supported by your computer's bios.
