Hello guys. I have very big problem when I try to make fresh install of Windows 7. I separate my HDD on "C" (system) and "D". Booting normaly. Setup starts and everything is "Ok". When I go to partitions screen I format my C and after that this error appear: "Windows cannot be installed on this disk. The selected disk is of the GPT partition style." and I can't continue the setup. I read many posts and almost everywhere the only thing to do is delete all partitions and create them again which will delete all my information from "D". I'm looking for information is there any other way to fix this problem. One friend told me I have to set proper boot device from BIOS, and there is a two DVD boot devices but I have only one on my laptop. The first device is UEFI: DVD (etc.) and the second P02: DVD (etc.). They are same but one says is UEFI. When I want to install windows in MBR drive should I choose second option? After that the problem will not happen again and I will no need to format all HDD? Thanks for the help! Sorry for my english which is not very good but I think you understand me.
