– Support for drive partitions larger than 2 TB.

Viewing Boot Settings
To view the Boot Settings screen, perform the following steps:
1 Power on, or restart your system.
2 Press F2 immediately after you see the following message:
F2 = System Setup
NOTE: If your operating system begins to load before you press F2, wait for the system to nish booting, and then
restart your system and try again.
3 On the System Setup Main Menu screen, click System BIOS.
4 On the System BIOS screen, click Boot Settings.
Choosing system boot mode
System Setup enables you to specify one of the following boot modes for installing your operating system:
• BIOS boot mode (the default) is the standard BIOS-level boot interface.
• UEFI boot mode (the default), is an enhanced 64-bit boot interface. If you have congured your system to boot to UEFI mode, it
replaces the system BIOS.
1 From the System Setup Main Menu, click Boot Settings, and select Boot Mode.
2 Select the UEFI boot mode you want the system to boot into.
CAUTION
: Switching the boot mode may prevent the system from booting if the operating system is not installed in
the same boot mode.
3 After the system boots in the specied boot mode, proceed to install your operating system from that mode.
NOTE
: Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit
operating systems do not support UEFI and can only be installed from the BIOS boot mode.
