Question, did you update your Acer to a higher Service Pack, and then try to recover your system with a later Service Pack.
Example to be clear: You were running Vista SP2, and tried to use SP1 recovery disk?
Don’t worry there is still help. Make sure you have everything you want off the HDD (hard drive). Your new option is a Clean Install. What this will do is delete, and reformat your HDD, and install vista that came with your computer on it. NOTE: EVERYTHING ON THE HDD WILL BE ERASED.
If you are ok with this it’s an easy process, takes about a hr. or so (depending on HDD size) to do. It does work very well. Example would be, 3 weeks ago, I took a Vista Gateway from Vista to Windows 7. (Didn’t know at the time you CANNOT do a clean install of windows 7 until you install it normally over vista). Broke the machine, no OS, nothing.
Inserted the Vista recovery disk, and did a clean install of it, and it came up fine. So it should, (meaning unless some hardware is broken, etc.) work.
Here is a guide for doing this. Click here for it. (skip Post install steps if you want.) If you have any questions I am on each night around midnight CST USA. I will try to check back tomorrow during the day, to answer any questions. Remember read the whole guide first and read twice click once. If something is not clear please ask me before you do it...

Lastly, BEFORE you do the above, boot your computer, and get into BIOS (F10, F8 etc.). Make sure your BIOS is not password protected, all security etc. is off. This can stop a upgrade. There should be a default option. Take pictures of each screen before you reset this with your phone or camera, just in case something happens. That way you can change it back and try again.
