    UEFI or Legacy?

    So i went for a clean Windows 10 installation on my Aspire E13.
    To boot from USB i had to switch from UEFI to Legacy, otherwise the USB drive would not be listed.

    However. After the installation was finished my touchpad was not even recognized, i mean, i was not even listed in the device manager, so i read somewhere on the Acer forum that switching back to UEFI would solve this problem.
    Well, i switched back to UEFI and now when the laptop start i recieve a message that says -No bootable device found!

    Even if i try to use my bootable USB drive, the list is empty.
    So i switched back to Legace again and guess what. Windows 10 starts like there was no problem.

    So, what's the different between UEFI and Legacy? The bios tells me -Use UEFI on Win 8 and above to use all the benefits.
    And why oh why can't i boot up from a existing and working Windows 10 drive using UEFI?

    I have switched Legacy to UEFI and now my laptop is working very slow. What should I do?

    I can't switch from UEFI BIOS boot to Legacy.

    If you switch from BIOS UEFI to BIOS Legacy you will want to have a drive with MBR partitioning.

    If you switch from BIOS Legacy to BIOS UEFI you will want to have a drive with GPT partitioning.

    There are exceptions but the above are the general rules.

    The ideal time to switch from UEFI to Legacy or Legacy to UEFI is during a clean install.

    If you have files backed up then you can easily switch from one to other by modifying the BIOS settings.

    The BIOS settings during a clean install will create the applicable drive partition architecture.
