So my weekend was largely spent up to my elbows in the virtual (one might say essential) guts of my laptop, backing up files before loading from the original system disk in order to do a full purge of the overcrowded digital quagmire that came as the result of my Windows installation accruing five years' worth of academic detritus, unnecessary applications, and porn. Lots and lots of porn. This turned out to be both a practical and a scholarly pursuit. As I discovered, you can follow the instructions in the A+ certification book perfectly, but there are still lots of ways to cock up a dual-boot arrangement between Windows XP and Ubuntu. That's why it took me two full tries before I got it right. Once I have completed this document, it will be saved to my Ubuntu partition, which will still have left over something in the realm of thirteen gigabytes. That's a vast improvement over the cramped setup I'd been working with before.
Anyway, things seem to be going peachy. The vast majority of the hard drive is now empty, I can move crucial data back into local storage whenever I feel the need to (thank God for external hard drives), and Ubuntu doesn't bitch at me every time it needs to update because it doesn't have enough room to breathe. I'm sure the other shoe will drop eventually, but until then I'm going to enjoy operating almost exclusively out of Ubuntu.
Because seriously, Windows? Way more trouble than it's worth.
