According to your description, I suggest you refer to the following information:
I suggest you try to find other regular CDs and put them in your machine to see if they can be read normally. If other CDs can be read normally, then the problem of your machine's optical drive is not serious, and the problem you mentioned is probably caused by the optical drive problem. If your machine can't read other regular CDs, I suggest you find a regular, pure installation version of the system installation CD, and set the CD boot as follows to see if the machine can boot into the system installation interface. If you can't enter the system installation interface, it is recommended that you contact the local gold medal service center as soon as possible for testing and processing. There may be a problem with the CD hardware:
① Restore the BIOS default value of the machine, put the installation CD into the CD-ROM drive, and restart the computer.
② When the "HP/COMPAQ" sign appears on the screen, click the "F9" key continuously.
③ Select "CD/DVD ROM Drive" and press Enter to confirm.
Note: Due to different models, the interface of CD-ROM boot is slightly different. Please select a representative CD.
For the contact information of the Gold Medal Service Center, you can choose your province and city and the product type you use through the following websites:
