Even though they exist, I haven't had much use for bootable Linux CD's
(only needed it once to rescue a Linux hard drive). However, I've
needed a bootable Windows CD a number of times but didn't have it. I'm not that talented with the minutia of Windows administration. Hopefully, this will come in handy the next time I need it. (Thanks to ryumaou at Diary of a Network Geek for the pointer).
