"When I turn on my HP Pavilion computer that running Windows 10, it doesn't boot normally but gives a black screen with the error message as follows:
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
To fix disk boot failure in Windows 10, try restarting your computer in Safe Mode and then enable the Windows Boot Genius or Windows Boot Manager. If that doesn't work, you can use a Windows installation media to repair your system. If the issue persists, you may need to run a disk check and repair any corrupted files. Additionally, you can try running a System File Checker (SFC) scan to identify and replace any corrupted system files.
The DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER error can be caused by various events, including a faulty or missing system disk, a malfunctioning hard drive, a corrupted boot sector, or a problem with the computer's BIOS settings. This error message is often displayed when the computer is unable to find the operating system on the disk it is trying to boot from, or when there is an issue with the boot process itself.
Having realized how DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER error occurs, it is time to learn how to solve this issue. Firstly, you can try some quick solutions such as checking the boot order in BIOS, trying to boot from a different drive, or using a bootable USB drive. If these methods don't work, you may need to reinstall your operating system or seek further assistance from a professional.
▶ Disconnect all external storage devices like USB flash drive, external hard drive and so on. Then, reboot your computer.
▶ Examine whether cables are loose or dead.
▶ Check the boot order. Press a key (the key can be different on various computers and you can refer to the user manual of your computer if you don't know the accurate key to enter BIOS) to access BIOS upon rebooting and see whether the hard drive contains Windows is listed first in boot order. If not, set it as the first boot device and reboot your machine.
If the methods mentioned above are not effective, you can try resolving the issue using a Windows installation disc or a third-party software.
If you're having trouble booting your laptop or desktop, and you're sure the operating system is on the correct hard drive, try booting from a Windows installation CD/DVD. This might allow you to troubleshoot and fix the disk boot failure in Windows 10.
1. Check hard drive error
To check and fix errors on a hard drive, follow these steps:
1. Go to Repair your computer >Troubleshoot; then, choose Advanced options and Command Prompt.
2. Type chkdsk /r c: and hit Enter key.
3. Exit the Command Prompt, remove the installation disc, and reboot from the repaired hard drive.
Notes:
▪ The "r" parameter locates bad sectors on your hard drive and fixes errors.
▪ If the boot drive is not "C", you should replace "C" with the correct bootable drive letter for your computer.
2. Fix corrupted Windows system files
System File Checker is a tool that allows you to scan for corruption in system files and restore corrupted files. To run it, you can follow these steps:
1. Access Command Prompt interface.
2. Input sfc/scannow and press Enter key.
After checking and fixing errors or repairing system files, exit the Command Prompt. Remove the Windows installation disc and try booting the computer from its system hard drive to see if it boots successfully.
To fix the issue with SFC Scannow not working in Windows 7, 8, or 10, try running the command as an administrator, check for corrupted system files using the command `sfc /scannow /offwindows`, or use the DISM tool to repair corrupted system files. You can also try running the command in a Command Prompt window with elevated privileges.
If you don't have a Windows installation CD/DVD, you can use the free repair tool Qiling Disk Master Standard to solve disk boot failure issues in Windows 10, including problems with inserting a system disk and pressing Enter. This tool allows you to create a bootable device, check for hard drive errors, and more. You can download it and learn how to use it to repair boot failure issues.
