If you have any "special" Acer features on your laptop, you will get a driver
problem going with another installation disk. Those can be fixed, but it may be a pain.
Example: I have a HD screen on my Sony laptop. I wanted to "improve" the driver only to end up with a generic driver that made my screen so dark that I could not id anything on the screen anymore. Fortunately I had an image from the previous day to where I could go back.
Another example: I have a backlit keyboard. The settings for it are in "Sony only" registry keys. If I used another system disk, the backlit keyboard would not work.
