I searched the web a lot but could not find anyone resembling my problem.
I have Windows 7 Professional in my laptop. I downloaded the 32-bit Windows 8 Release Preview iso from Microsoft's website using Free Download Manager. I used the Windows7-USB-DVD tool to copy the iso to a flash drive (I later did it using WinUSB Maker, but the problem is still there).
When I boot from the flash drive its gives the following error right away:

The application or the operating system could not be loaded because a required file is missing or contains errors.File:\windows\system32\winload.exeError code: 0xc0000001You must use the recovery tools on the installation media. If you do not install media (such as a disk or USB device), you contact your system administrator or computer manufacturer.Also, when I run the setup.exe on Windows it gives the following error:

Use the other installation disc that says 32-bit. When you insert it, Windows 8 Setup will restart automatically.The parameter is incorrect.[Error = 0x80070057]Any suggestions will be highly appreciated.
