Re-installing or upgrading your existing operating system to the latest version can be a very tiring job. If you do not know the correct procedures to go forward, you will be stuck in between and nothing can be accomplished but errors on your screen! Stop errors or Blue screens are very common types of errors found when you try to install a new hardware device or a latest version of your operating system.

You may be planning to upgrade to Microsoft Vista from Windows XP and during the process of installing Windows Vista, you get the following error message:
Windows cannot open the required file D:\Sources\Install.wim. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007000D
Generally, this error is generated when you are activating Windows Vista by running the Windows activation process. This reflects that your initial downloading may be corrupted. In another scenario, you want to use Windows Vista on your computer but due to some system incompatibility issue, you get this blue screen on installing the operating system:
STOP 0x0000000A (parameter1, parameter2, parameter3, parameter4)
IRQL_NOT_LESS_OR_EQUAL



While updating your Windows you could also face file corruption issues like this:
Error found: Code 0x80240029

This error is generated when you are facing a Windows Update problem or your software distribution folder is corrupted.
