    EFI System Partition After Re-Install


    Hello

    I reinstalled windows 7 today, When i got to the part where i have to format my SSD it wouldn't let me so i clicked "New" Then started the install.

    Once installed, I go to disk management and i see "100mb EFI System Partition"

    Now, Before i re installed windows i had just 100mb Windows Reservered, Why do i have this EFI thing instead?

    When i started up my PC Before it would take about 16 seconds, Now it's around 2-3 Seconds more.

    Anybody tell me why it installed this partition and can i remove it?

    Thanks

    It seems you installed in UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

    This video explains the difference between UEFI and Legacy BIOS:



    If you find it gives you advantages with a BIOS GUI, supposed faster boot and the others mentioned then you might want to keep it. If not you can Bypass UEFI to Install WIn7
