How can I undo a first installation on my computer?

[Irving]

I'm trying to set my Nook up on my new computer. It was super easy on the laptop, but I messed something up on the new desk top.
I my computer to not recognize the Nook when I connect with the USB cable, as whatever I did, the computer tried to set the Nook up like I have a mac instead of Windows. So now when I connect, it asks if I want to open the files like it is supposed to, but isn't set up the correct way. Is there anyway to undo that initial set-up?

dd if=/dev/zero of=/dev/sd0 bs=8192

Do I run that in the Run box, or is that a joke that will destroy my computer?

Are you sure the computer does not know when the nook is pluged in? Windows? What kind? Are the laptop and desktop both the same? Can you only "authorize/register" the nook on one computer? I'd check it out in the control panel/device manager. From there you should be able to uninstall drivers. I know nothing about nooks, but just making it connect should be straightforward.

My windows computer creates "recovery points" when installing software or hardware, or simply updating software. There is a list of these recovery points, organized by date. I think you should be able to choose a recovery point generated prior to the installation of your new Nook, and your computer will revert back to it's previous state. After that, you can try the installation again.

If there is a way to reset the Nook, I'd consider doing that as well.

COcz, the computer knows when the Nook is plugged in, it is just reading it incorrectly.
Brass, the Nook help people suggested I reset the Nook, but then I'll have to re-download everything I have on it and re-register it with the Nook site.

The issue is that the first time you plug in the Nook, you click on it and there is only one file, a link that leads you to the site to download the set-up file. The problem was that the one it downloaded (automatically) was the set-up file for Mac. My computer can't read it, and I have no options to choose the right one.
Looks like I have Windows 7, 64-bit. I think the laptop is Windows 7, 32-bit, but not entirely sure. I may try the recovery point.

Thanks for the tips.

Unless you know how to uninstall drivers and scrub the registry by hand, your best bet is to try for a restore point before you plugged the nook in. That should uninstall the information and driver files, and hopefully let it proceed forward as it did on your other system.

Failing that, you'll need to figure out how to uninstall the mac information and download and install the win7,64 installation file.

Hey guys, Windows 7 makes it really easy to do the restore point. I already did it in fact. Later I'll try the Nook again. Thanks, as always, for all the help.

dd if=/dev/zero of=/dev/sd0 bs=8192

This command will write zero's to every part of the hard drive at sd0. It is a pretty decent way to wipe a drive, but I prefer this:

dd if=/dev/urandum of=/dev/sd0 bs=8192

This would not be a good way to fix a computer but it is great for getting it ready for disposal.

Just so people don't think that I was trying to ruin Irving's day -- the command would not have run on Windows. Its linux thing.
