boot disk recommendations for grub and ubuntu?
I'm still kinda new to linux. I've been learning my way around the command line and been experimenting with linux on a couple computers of mine. Occasionally after trying a few things, grub or linux won't load right. I've done some research on possible tools to help but I was wondering if any of the more experienced users had some recommendations for boot disk or tools to help repair grub and/or linux desktop/server editions. Any help would be much appreciated. Thank you for your time and effort.
p.s. I would also be interested in any fun and interesting tools, programs, and/or repository's that other users have found beneficial. Thanks again.
