If so, and even if not, try a duplicate of that DVD but record it at a lower speed and clean the CD/DVD lens.
The story you present is too light on detail. If it's not the Gateway recovery media, you may encounter too many errors.
I am trying to recover my Gateway M-6307 from a vista boot disk and as soon as I put in the product key to allow Vista to install a cancellation notice comes up saying "Windows can not open the required file E:\Sources\install.wim. The file does not exist. Make sure all files required for installation are available, and restart the installation. Error code 0x80070002" Any help would be appreciated, thank you!
