How to resolve the error during CentOS 7 installation where the installation disk cannot be found?

If you encounter an error of not finding the installation disk when installing CentOS 7, it may be due to the following reasons: 1. Storage drive not correctly recognized: In some cases, CentOS may not correctly recognize your storage drive. You can try the following steps to solve this issue: make sure your storage devices are properly connected and functioning properly. Check the settings of the storage devices in the BIOS to ensure they are correctly configured for installing the operating system. Try changing the mode of the storage devices in the BIOS (for example, switch from IDE mode to AHCI mode). 2. Missing drivers: Some hardware may require specific drivers to work properly on CentOS. If your hardware is not compatible with CentOS, you may need to manually install the appropriate drivers. You can try downloading and installing the necessary drivers from the hardware manufacturer’s website. 3. Issues with installation media: If you are using a CD or USB drive as the installation media, there may be issues with media corruption or production errors that prevent recognition. You can try recreating the installation media using another reliable medium and try installing again. 4. Other issues: If the above methods do not solve the problem, there may be other unknown issues causing the installation disk not to be found. In this case, you can try searching for relevant CentOS installation problems and solutions, or consult the Linux community or CentOS official support for more help and guidance. Please note, before performing any actions, back up your important data and proceed with caution to avoid further damage.
