So I've got a new PC coming and this time it's the first time I will be using UEFI, i have read all the big stuff but I don't have the hardware yet so It's still kind of half baked but I'll do dig deep into it once I start building in the coming days. I've read the win7 install guides, MS GPT FAQs (not fully yet), etc, But I wish to know if: I can use UEFI as an upgraded bios without having to use GPT disk format? GPT disks can have any sort of partition cloning for full operational OS backup ? Will GPT format improve performance on SDD or improve reliability in terms of data integrity or error rate? When isntalling win7 with MBR but using UEFI, will it work normally without needing to uefi-boot the window7 install? If I cannot backup my OS in a 100% clone that will boot normally when recovered, i will probably not use GPT, that shit is a step backward.
