If any of the above fails, here is my philosophy. I started with Linux last July on a new hdd. Completely gave up Windows. The first thing I did was create a boot, root and home partition, and a couple others. Over those months I have encountered problems, tried to fix them and probably screwed a few things up due to my limited Linux knowledge. I did the searching, posting, trying various suggested methods etc. That takes time. If this fails, I find it so much simpler to reformat and reinstall an OS or maybe an updated one, or maybe a different one. If I keep a few notes, I can reinstall all my programs, all my Firefox addons etc. in maybe an hour, and I am right back to where I started, maybe with better results this time. Hey, just my way of doing things.
