linux is useful for a lot of things, but some people dont want to install it, or burn it to a CD. Here's how to boot in from within windows. Tested on XP, but should work for vista. Confirm anybody? Requirements: Windows Computer USB portable storage device Your favorite Live Linux or other LiveCD image (ISO) Custom StartLinux.exe including Qemu, Kqemu files The Process: 1. Create a directory on your USB device named QStart 2. Download the self extracting 7-z StartLinux.exe file 3. Run StartLinux.exe and extract the contained files to the QStart directory on your flash drive 4. Download your favorite Linux CD (ISO) Image and copy it to the QStart directory on the flash drive 5. Double click the StartLinux.bat file to boot linux directly from the portable flash device This configuration reserves 256MB of system memory for the virtual Linux operating environment. If you wish to increase or decrease this capacity, edit the -m value on the last line of the StartLinux.bat file.
