How To Change Boot Mode
 

I´m using boot repair, and it gave me the message:

"The boot of your PC is in EFI mode. Please change it to BIOS mode. Do you want to continue?"

How do I change from efi to BIOS mode?

the same way you would have on a windows computer
hit the f8 or f2 key during the first 3 sec of the boot

Hi,

Welcome to LQ!

As JohnVV stated the hot keys to use may be F2 or F8 but if you have a boot screen then actual keys to use will be displayed to actually setup the mode. You do have documentation for the system? If not go to the manufactures site and read the procedure for your system. Some systems have a silent mode and sometimes the boot screen will not be displayed but the keys are still functional. You can look at 'EFI/UEFI' to get a general understanding for the protocol.

Please look at the following;

FYI: I suggest that you look at 'How to Ask Questions the Smart Way' so in the future your queries provide information that will aid us in diagnosis of the problem or query.

From other posts it seems you don't want to do that. Changing how the system is may only create other problems.

One post suggested that the actual problem was video. What issue are you having?
