Makb :
Thankyou very much for your reply... I have called acer for the disks and they said they don't have them anymore... As the computer is too old or they don't hold them and give them out anymore ? When did you get yours ?
My problem was on my desktop a couple years ago, and they did send me the disk free of charge, but only after having a complete meltdown and lots of angry phone calls. I know that they have been doing this same thing for both laptops and desktops. It most likely has to do with money. If they provided everyone with 'real' recovery disks then they would probably have to pay a royalty to Microsoft. (I'm assuming this is the reason, I really have no idea, it could just be incompetence too...)
So, your options at this point are to obtain a retail version of Windows and use that to do a clean install, then you would have to download any additional software specific to the Acer from the Acer web site, however, if it is too old and they have removed that software as well, again, I can't help but rant here since, the costs of leaving the software in place would have been minimal, but I digress, if the software is no longer available then you will have to make do with what Windows recognizes automatically.
Prior to doing this option, I would ask why you are doing a factory restore.... depending on your answer there might be alternatives. If your recovery partitions are in tact, have you attempted to boot into the windows recovery partition? I think Alt+F10 is the default for Acer as the computer is booting up... Also, perhaps, depending on what your root issue is/was (I'm assuming that you had some sort of problem and that you aren't doing this just for fun) perhaps a linux livecd such as: "Utlimate Boot CD" or "Hiren's Boot CD" could help, especially with issues like corrupted partitions and/or boot loaders...
Why were you attempting to restore the system?
