I get this error whenever my system is trying to extract the Windows files. While extracting it gets stuck at 70%. I've been attempting to dual boot Windows 7 and 8 (Standard edition) by various ways and finally got one way to work. Problem is that after I've finally got the installation process started now it wont finish. If anyone has a work around on using an installation disk like maybe a download from Microsoft themselves. Any help would be appreciated, thanks!

This error appeares in case od bad media.

the code means CRC error

You should also check if your HDD is fine. Run a HDD diag tool from your manufacture and open the recovery options of the Windows DVD and run chkdsk to check for NTFS file system issues
