After about 2.5 hours of backing up my XP and Linux data to my new USB external hard drive, I popped in the Fiesty install CD and wiped the slate. In a relatively quick 40 minutes, I was back up and running. I had no problems with the install at all. Very nice.
But boy did I ever do a lot of tweaking and customization to my system over the past year or so. You don't realize all the fiddling you've done until it's all stripped away and you're back at square one. I've got a lot of re-tweaking ahead of me, but at least I'll now be running XP-free on this machine (at least in the non-virtual sense if that means anything). Anyway, it's sometimes refreshing to start with a clean slate.
I've now got about 90MB of updates to download and install - seems like the perfect time to let it do it's thing while I sleep. ;)
