I know just enough to get myself in trouble when it comes to computer stuffs.
I am trying to remove Ubuntu from my laptop (an Acer Aspire) and install Windows. If I put in the boot disk and select the disk as my boot device, I can access start up, but run into a problem. Something about how it can't install Windows onto the partition. (Two are available, the primary partition and one that has 1 MB of space. I don't know why.)
So I tried another method-formatting the hard drive. This also failed, as when I tried, I got the error:
Error unmounting /dev/sda1: Command-line `umount "/dev/sda1"' exited with non-zero exit status 32: umount: /: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)

I have no idea where to go from here. I'm totally and utterly lost. Help?
I've reviewed other similar questions, and none explain how to deal with the problem I face here.
