How do I boot from CD/DVD?

I burned DBAN to a CD and then rebooted the machine with the CD inserted in the drive. To my surprise, it just booted right back into Windows. What gives? How do I get the computer to boot up from the CD?

This is actually a pretty common problem with a relatively simple solution.

Your computer’s BIOS needs to be instructed to check for a bootable CD or DVD before it tries to load whatever is on the hard drive. Right now, your computer is configured to either ignore the CD/DVD at boot time or check the hard disk first.

And because there’s something bootable on the hard disk – namely Windows – that’s what it boots into.

As I said, a simple solution conceptually.

The devil, as they say, is in the details.

Are we at risk of losing our digital information over time?

Today, lots of information is being stored electronically. Years ago, it was on books that lasted 100’s of years, if you wanted. Try reading a 1984 3.1/2 floppy disk or worst, a 5.1/2. The 8 inchers are before my computing time (I saw them on Wargames). The ones with the reels that stopped and started are really unreadable. I also used a tape drive on a commodore Vic 20. If I did not hoard this stuff, it would be all unreadable, as I have not used this stuff in 34 years. So are humans in danger of losing knowledge on this? Magnetic media degrades faster than paper books or doesn’t it?

I think you raise a very good point.

While I still feel that digital information is vastly superior to analog counterparts like paper in most respects, that doesn’t mean that there aren’t drawbacks – often serious drawbacks – with storing information digitally.

And one of those drawbacks is progress.
