I pressed shift + restart and it loaded BIOS menu, where I restored BIOS setting to default and I closed it, but now every time I boot my PC UEFI BIOS is loaded and I can only enter windows by pressing F12 and going to windows boot manager. How do I solve this? (DELL G5 5590)

• There is no any hardware failure
• bootrec.exe /fixmbr didn't work
