Windows 8 error code 0xc0000260

When you try to Install Windows 8 Consumer Preview from a the DVD, it fails with blue dump and gives an error code 0xc0000260.

This error is coming because you can not run Windows 8 customer preview on a PC with a CPU that does not support Physical Address Extension (PAE).  Early Pentium CPUs with the 400Mhz front side bus (FSB) do not support PAE.

PAE is a feature which allows 32 bit CPUs to access physical address space in memory and memory-mapped devices larger than 4GB such as RAM.

It is advisable to check the hardware compatibility list before trying to install Windows 8 CP on your hardware.
