Hi all, I don't know too much about hardware nor software of a pc and just learning stuff as I go. Any help is appreciated thanks. Here is my issue: i just got a new hdd (because my old one stopped working, malware virus something idk) but when i try installing win7 on the new hdd, it gives me an error saying that i cannot install win7 on a gpt partition type hdd. now this is all happening on the os installation screen (where it asks to choose a partition to install win7 on) i tried formatting the new hdd while in the same menu, and when i click on "Format" nothing happens, cursor dissapears for about a second and then thats it... i just recently purchased everything new from cpu to mobo to ram to case to heatsink all of it, been over 2 months to put this pc together so im a bit stressed. if anyone could please guide me into installing win7 on my hdd, would be thankful. thanks.
