    few questions regarding the Windows 10 installation in UEFI mode

    First of all thanks for the excellent guide.

    I have a few questions regarding the Windows 10 installation in UEFI mode:

    I read in a couple of websites that for the installation and boot to be in "full" UEFI mode the option CSM must be disabled, can someone confirm this?

    I have a GeForce GTX 460 which does not have the necessary GOP feature to have a UEFI boot, can i turn on the CSM option for a Legacy boot despite having Windows 10 installed in UEFI mode?

    Can i format (in GPT mode) and partion my hard drive prior to the Windows 10 setup? Would i still need to delete all partions in the Windows setup to get the 4 partitions necessary for the UEFI installation? Or will they automatically appear since the hard drive was previously formated in GTP mode?

    Thanks in advance and sorry for the bad english.

    Need some Clarification....
    1. The OS you are updating from (7 or 8.1)
    2. The Current Boot (UEFI secure boot On/Off or Legacy)
    3. Sata Operation mode in BIOS (AHCI or anything else)

    If running win8 or 8.1, no changes are needed to be made in BIOS while updating
    If running 7 thing go a bot trickier..
