As far as I was aware, I wasn't downloading any images - just updating the software I had. Was that not what the instructions I gave to the computer actually said? Also, in terms of hardware, I got the pre-loaded SD card with the Pi, so that cannot be incompatible.
Looks like this IT lark might be harder than I anticipated!

I have seen a lot crazier things than that. You really can't assume that the image is correct; old image, corrupted image, incompetent supplier, bad SD card etc. Also, upgrading software is usually OK, but newer software, especially firmware, can occasionally break things that used to work; but certainly if the image was wrong or corrupt in the first place, things are going to go bad fast.tugger wrote:Also, in terms of hardware, I got the pre-loaded SD card with the Pi, so that cannot be incompatible.
It is an image in a similar sense as with a camera or a mirror. Not the original scene (or disk) but a virtual replica that duplicates all the details.tugger wrote:Am I right in thinking that the term "image" has a broader than normal meaning in the IT world, i.e. "file" rather than "picture"?
Yes, as opposed to backing up just files and folders, an image of a hard disk or in this case an SD card, is a bit by bit copy of everything on the media including hidden information like the Master Boot Record, partition information, etc. As was mentioned, it is an exact mirror of the media, including even empty space that may exist. An image allows you backup and restore a system exactly as it was at a point in time with just one file.tugger wrote:I have a spare SD card so will have a go at this.

Really great and helpful forum though, thanks
