A Disk Read Error Occured. Press CTRL+ALT+DEL to restart

A disk read error occurs when your Hard Drive has problem or BIOS setting are not correct. It may be fixable through BIOS settings or could be unfixable and you may need to replace your Hard Disk.

1. To fix it through BIOS first enter the BIOS settings
2. Look for the Reset to defaults or Load default settings option in the BIOS, reset to defaults . After resetting to defaults restart it.
3. If this doesn't work then another way to solve through BIOS settings is look for a setting called Plug and Play OS it should be set to YES and restart.
4. If this method also fails then try to find an option SATA mode change the mode and then restart. 
5. If this doesn't works then Under diagnostics Utility there must be a test for your Hard Drive. Test your Hard Drive for Errors. If there are errors then your hard disk needs to be replaced.
