I bought a Samsung laptop (Model: NP350V5C-S0BIN) which came preinstalled with Windows 8. I dont like Windows 8 and want to install Windows 7. I have disabled FAST BOOT and SECURE BOOT.
My questions are.
1) On disabling Secure Boot, I found three OS Selection Modes namely, "UEFI", "CSM OS" and "UEFI or Legacy OS". Which one should I choose to install Windows 7 x64 and Why? (Really confused as in some forum they are telling to use UEFI while few other forus telling "UEFI or Legacy OS")
2) I converted the GPT to MBR once I tried to install windows 7 unknowingly but the installation failed. So if I select UEFI DVD Drive to install, will it automatically convert MBR back to GPT upon creating partitions?
Please provide the sufficient help.
