Hello, it is very likely that the CD drive will automatically search for the CD when the computer is started. That is to say, the laser head is working, and the longer the time goes on, the weaker the laser emission will be, which will result in the inability to read the data. Another possibility is that there is dust. It should be OK to wipe it with alcohol.
It seems that the area to be selected for the Mac system is that if you select the wrong optical drive three times or five times, the optical drive will be disabled??I don't know if you'd better go to Win and see if you haven't installed a driver -- # Try installing a driver yourself
The prompt means that there is no boot disk. There are several possibilities. Either your boot order is not the priority of the hard disk, check whether there is a CD or a USB flash disk inserted in it, or the hard disk is damaged. Check the connection and hard disk. However, as you are a notebook, it is not recommended to disassemble it yourself. Take the IT department of your company to check it or check it after sales.In addition, I suggest you find a bootable USB flash disk or CD-ROM drive to start up. After starting up, check whether the hard disk can be read out. First, make sure whether the hard disk is the problem before sending it for repair.
Of course, the dust entered the optical drive and damaged the laser head. This is the answer to the saying "running water does not rot, and household hinges do not bark"
