    New install for new UEFI capable board


    I expect to receive my new Asus Hero board and i5 4670k at the beginning of this coming week. I've built several systems, but not since '08 and am a bit confused re: UEFI. I plan to use my existing Sata II mechanical HDDs for the time being. It seems like the more information I get, the more confused I get.
    I'll be doing a fresh install of win7 x64.

    So my questions:

    1. can an mbr HDD use uefi?

    2. Are there benefits/caveats to mbr/uefi )? Is it better to use GPT (keeping in mind, mech HDD)?

    3. I'd like to install from a 4 GB patriot USB thumb drive. I have an iso of win 7 x64 w/sp1 slipstreamed. Should I use the Create Bootable Win 7...tut or UEFI Bootable USB...tut ?

    I do have a 1TB WD sata6GB drive that I use in a docl for backups. Preferable to use as sytem drive in this case?

    I appreciate any pointers or URLs. Thanks for your patience with what must be elementary questions for those in the know.

    Watch this video to better understand UEFI BIOS vs. Legacy BIOS - YouTube.

    The only way to boot an MBR HD with UEFI is to disable any Secure Boot and set Compatibility Support Mode (CSM) or Legacy Mode to Dual or Enabled.
