I am facing some problem with my computer. I am having the Windows 7 installed in my computer. It is the fresh installation and there is no other Operating system installed in my computer. There is no problem while booting the computer but when I try to pick a hard drive to install it then it does not accept that. It permits me to delete the partitions but when I click on the "New" or "Format" then it does not respond me anything. Please tell me that what is the problem with that and how can it be solved. Please help.
