I have a Dell Inspiron 1521 that failed. A complete Factory restore is required to fix the problem. But, It errors every time. I get the following error:
Windows cannot install required files. The file does not exist. Make sure all files required for installation are available, and restart the installation. Error Code: 0x80070003.
I installed a new hard drive and first tried using the installed partition, then I tried manually creating and manually formatting the partitions, many different ways. No matter what I try, I get the same error. The disk I am using came directly from Dell, I have also tried using 2 other Windows Vista DVD's, Nothing is working...Any suggestions would be appreciated.
