How to resolve the issue of not being able to find local disks when installing CentOS 7.

When installing CentOS 7, not being able to find local disks is usually caused by a few different scenarios.

1. Driver issue: specific disk drivers may need to be loaded in order to recognize local disks.
2. Ensure that the local disk is enabled in the BIOS settings.
3. Hardware connection issue: Make sure the disk is properly connected and verify that both the power and data cables are securely connected.

Here are some possible solutions:

1. Check drivers: Before installing CentOS 7, you can try to load drivers on the installation interface. The installation program usually offers an option to load drivers. If you know the model or manufacturer of the disk, try looking for the corresponding driver on the official CentOS website and load it.
2. Check the BIOS settings: Access the BIOS settings interface of the computer to see if the local disk is enabled. The specific steps may vary depending on the brand and model of the computer, but typically you can enter the BIOS settings by pressing the key displayed during computer startup (such as F2, Del, or Esc).
3. Check the hardware connections: make sure the disk is properly connected, and both the power and data cables are securely attached. You can try re-plugging the disk and check if the connections are firm.

If you have tried the solutions above and still can’t find the local disk, it is recommended to contact the hardware supplier or computer manufacturer for further assistance.
