|Sorry dudes , its windows xp pro .|
Boot from the XP CD, press any key when you see the very brief message, delete all the partitions & format to NTFS.
Do not press any key again message after reboots, during the installation.
this is a dell system
I try to delete the partition , but it says cannot access disk .
after this I push enter, and we get the blue screen of death . , saying check if your new hardware is installed properly .
