Asus Vivobook S510UN does not enter UEFI BIOS settings
Hello,
I have an Asus Vivobook S15 S510UN laptop. I installed multiple operating systems on it: Windows, Linux and macOS. I have used it for more than 1 year with this configuration. I noticed that my laptop does not enter UEFI BIOS settings today. I believe this problem started with Linux grub update when updating kernel but I am not sure. I can use and boot into Linux and Windows without any problem.
If I press F2 when starting laptop, it should enter UEFI BIOS screen, but I just get blank screen. If I press ESC when starting laptop, it displays boot devices list menu without any problem, and I can boot any boot device I want. So as far as I understand there is no problem with using this laptop except for entering UEFI BIOS. If I don’t need to change any BIOS settings, there is no big problem. But I want to fix it, because some day I may need to change BIOS settings, and that day I can’t enter UEFI BIOS.
Anyone can help me to fix this problem?
