Does it make a difference? No. UEFI sucks (for now).

  • The only speed-related improvement related to UEFI is a shorter post time, which means the rate at which an OS boots can only be shortened by a few seconds at the most. People likely to see the best performance enhancements are people with multi-boot systems, as I believe UEFI can initialize hardware and load kernel files asynchronously (I might be totally wrong on that, though :P ). If all you want is a shorter boot time, invest in a better processor and an SSD.

  • @hraqhraq Uhh.. UEFI and BIOS are nothing to do with OS?

  • So, what's your point? That UEFI and BIOS takes an equal amount of time (about 13 seconds) to do POST and load the bootloader, on the same machine?

  • you have to install windows 8 to see the big difference.

    Windows 7 is not optimized to uefi only 8 is.

  • The way I understand it, UEFI increases boot time NOT loading time. UEFI cannot improve anything about Windows loading time.

  • DO you have trackpad issues ? or it's just me ?
