I try to upgrade my Inspiron 1521 OS from Windows Vista (32 bit) to Windows 7 (64 bit). The hardware is 64 bit capable. After booted from GD/DVD, I get the following error messages:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Windows has encountered a problem communicating with a device connected to your computer.

This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removable storage is properly connected and then restart your computer.

Status: 0xc00000e9

Info: An unexpected I/O error has occurred.

I have checked the DVD drive and it works properly on reading and writing data.

Anything I can do to resolve this problem?
