tahaimam hi, first off im not an expert or anything but I just did this today so I do know what im talking about. I really hope you have your original operating system instalation disk that hopefully came with the computer (if you bought it new or maybe even used) you are going to need that to reinstall your operating system. When you deleted the partition with fdisk you deleted all the information on your hard drive thus windows is no longer there. If you were trying to reinstal windows then you were taking the right steps. You must delete the existing partition, restart, create a new partition, format, then reinstall your operating system (hopefully with your original that came with the pc when you purchased it) NOTE* you may also require a registration key when reinstalling windows I did today when I reinstalled and it was located on the original book that came with the cd. Hopefully one of the monitors will go over this info and make sure it is all correct im pretty sure it is though. I wonder what is taking them so long to get back to you. Well good luck and if you have any more questions just post em! cya
