'Missing or corrupt Windows.BT\Windows\System32\driver\iastor.sys' (0xc0000359). I found a fix for this to correct this error (involved downloading the latest drivers from Intel). I then attempted to proceed with the Windows 7 update. This time I received the error 'Missing or corrupt Windows.BT\Windows\System32\driver\winload.exe' (0xc00000f). Can you please give me some direction on successfully completing my Windows 7 Upgrade.
Thank you very much.
