Hi everyone, I'm about to build my new PC with an ASUS P8Z77M MoBo, which has UEFI, and I want to install W7 Ultimate x64 with DAZ's Loader, which is the best option from what I've heard. I know that maybe a bunch of people have post with this problem, and I've read some posts about it, but to be honest I don't know much about BIOS and related stuff, so I hope you can give a hand. For what I've heard, I just need to boot my W7 DVD in non-UEFI mode. In an old thread I read this: Does that mean that when I start my PC with the W7 Ultimate DVD I need to press F8 when the ASUS boot screen appears and select the option which does not have the "UEFI" tag on it in order to install in MBR? And that's all? If I do this, will I lose any features? I've read about MBR problems with large capacity external hard drives. I have a 2TB external HDD apart from my 1TB internal HDD. Will this affect me? Thank you beforehand and excuse me for my bad english.
