There is no boot window when starting the laptop, there is only a black screen with the inscription: 'Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key'. I did everything as described, I thought it was in the battery – I changed it, no, I thought it was hard – I checked it on the hospital – everything works fine, I checked the disk for errors – they are not. There were no flash drives and disks in the media. In BIOS, I reset the settings – there is no effect. In the main menu it shows the hard disk, in the boot menu it does not show the hard disk from which the laptop starts. What to do?
