How did the hotel computer break down like this? ?

Reboot and select the correct boot device or insert boot media to select boot. The hard disk can enter the system if it is successfully detected. Reasons for failure of hard disk detection:

A: The motherboard BIOS is dead, or the BIOS setting is wrong, so I can't remember the hard disk information. If your system date is incorrect, this may be the reason. Solution: Replace the BIOS battery and re-enter the BIOS to detect the hard disk. Open the chassis, take out the bright battery on the motherboard for a few minutes, and then try again. First, unplug the chassis power cord.

B:B:IDE/SATA cable is of poor quality or not plugged firmly. Solution: Replace the IDE/SATA cable or plug the IDE/SATA cable into another IDE/SATA slot on the motherboard. Do not connect the cable connected to the hard disk with other IDE devices (such as optical drive). Separate the two IDE cables and set the master/slave disks correctly.

The hard disk is broken and may need to be replaced.

D: There is something wrong with the boot sector of the hard disk. You can check in the BIOS first and see if you can find the hard disk in the BIOS. If the hard disk can't be found in the BIOS, it may be broken. If the hard disk can be found in the BIOS, set the CD-ROM drive to startup, put the system disk in the CD-ROM drive, and reinstall the system.
