Switch Between Legacy BIOS and UEFI BIOS Modes

The BIOS firmware supports both Legacy BIOS (the default) and UEFI. Because some OSes support both Legacy BIOS and UEFI BIOS and some only support Legacy BIOS, you have these options:

• If the OS being installed supports Legacy BIOS only, ensure that BIOS is set to Legacy mode before you install the OS.

• If the OS being installed supports both Legacy BIOS and UEFI BIOS, you can set the BIOS to either Legacy mode or UEFI mode. Set the BIOS mode before you install the OS.

  Note -  The Windows Server 2008 OSes support both Legacy and UEFI BIOS modes. You can choose which mode to use for the OS installation.
