Goes safely into BIOS mode

Uefi tricks: full power for your PC

Uefi mode active? How to check Uefi status

Uefi mode is not always automatically active, especially with complete computers with pre-installed Windows. If the Bios emulation CSM (Compatibility Support Module) is activated, the operating system is installed by default in conventional BIOS mode. To install Windows in Uefi mode, the PC manufacturer must call up the installation DVD from the Uefi boot menu. To check whether the Uefi mode is active, type the command in the command prompt while Windows is running msinfo32 a. The Microsoft operating system now displays the "Windows system information". Look for a line that begins with "BIOS mode", followed by "UEFI mode". If the information is "Legacy" or if the line "BIOS mode" is missing completely, then you are unlucky and Uefi is not activated. If you want to use Uefi in this case, you have to reinstall Windows. You then have to insert the installation disk and press the F8, F10 or Esc key when the computer starts up. "UEFI:" should appear in front of the entry for the DVD drive in the boot menu. Select this entry. Then press any key to start the installation program. Then carry out the installation as usual.

Bring Uefi up to date with the update tool

The Uefi is never completely flawless and many functions are only added later. This is why motherboard manufacturers often maintain the firmware of many motherboard models for years. Often you fix hardware compatibility problems, fix faulty or incomplete functions and expand support for new processor models that were not even on the market when the motherboard was purchased. So it is almost always worthwhile to update the Uefi. When there was only the classic BIOS, you had to laboriously find out the exact model name of your motherboard, download the update, save it on a bootable medium and then update it using special software. With a Uefi-capable motherboard, you can do this quickly and easily with just a few clicks of the mouse, as the update function is already integrated in the Uefi itself. Asrock, for example, calls the update routine "Instant Flash", Biostar "BIO-Flasher", Asus "EZ-Flash", Gigabyte "Q-Flash" and MSI "M-Flash". For an update, connect a USB stick formatted with FAT16 or FAT32 to a USB socket on the computer. Unzip and then save the update image there, go to Uefi and start the update routine from there. Be on the safe side before the update and use the backup function offered by all update routines. In this way you save the old Uefi version beforehand and, in the event of an emergency, you can use the restore function, which is also always integrated in the update routine, to restore the original Uefi version if the update should unexpectedly fail. Some mainboard manufacturers also recommend resetting the system to the factory default using the “Load Defaults” menu item before performing the update.
