Considering that I have 3500 Gigs of programs, pictures, music, games, and everything else that I own; it takes a little while for my tiny 500Gig drive to restore "that bloated image file".
But it's a lot faster than the rows of CDs & DVDs that I would otherwise need to install. I timed that before, and it was pretty close to your figure, except it was hours & minutes, not minutes & seconds.
Well, I guess you don't have a lot of data. Or maybe you keep it on a share at work. Me, I like my shit to remain personal. That's why I have only the data I don't care about so much connected to the net & everything else is on drives that I'll plug in if I require it. I should just build a 3rd computer & quit selling my old stuff whenever I upgrade.
Anyway Advocate, you might be able to install windows in less than a quarter hour; but you're still ugly.
