    MacBookPro 15 2.8 and cannot load Windows 7 through boot camp. Constant error "Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code 0x80070570" - have burned numerous copies of ISO file and even tried different media but to no avail. I get to approx 10% then this message occurs. Have seen this posted - never found a real fix for the issue. Am using Nero to burn image. Anyone have the answer?

    Have you checked that your ISO is good? MD5 and CRC hashes are published.

    Try erasing the windows partition and starting over.

    thanks much - you were right. Re-downloaded from digital river and second copy worked. Now if only I can get my MacBook Pro to see my portable WD Passport USB hard drive.... system doesnt even blink when I plug it in. On the windows side, says it cant load the driver! The drive is formatted NTFS. This sure is a learning curve.
