If the hard disk cannot be detected when the notebook is powered on, but can be seen and opened in the PE (pre installation environment), there may be several reasons:
1. BIOS setting problem: First, ensure that the SATA mode in the BIOS is set to AHCI or IDE mode.If it is set to RAID mode, you may need to install the corresponding RAID driver to correctly identify the hard disk.
2. Hardware connection problem: ensure that the data cable and power cable of the hard disk are firmly connected.You can try to plug and unplug the data cable and power cable again to eliminate the problem caused by poor contact.
3. Hard disk failure: It may be that the hard disk itself has failed.It is recommended to remove the hard disk and plug it in again after powering off the notebook, and then start the notebook again to see if it can be recognized.
4. Driver problem: When you enter the PE system, you can see and open the hard disk, which indicates that the operating system has loaded relevant drivers and is different from the BIOS.You can try updating or rolling back the disk controller driver to fix this problem.
5. Other software/security setting restrictions: Some anti-virus software, encryption tools or other security software may restrict access to disks.Temporarily shut down these software to see if it can solve the problem.
If none of the above methods can solve the problem, it is recommended to contact a professional computer maintenance personnel or after-sales service center for further inspection and repair.
