"Grub Rescue" - Troubleshoot Windows 10

If your PC does not boot properly, but you only get the error message "Grub Rescue" under Windows 10, there is obviously an error. Grub is a bootloader for Linux and actually has little to do with Windows.

Error message on Windows 10: Grub Rescue

When you try to boot your PC with Windows 10, but instead of the usual screen you see a command line that says "grub rescue", an error occurs while booting. "Grub" is actually a boot loader used for Linux operating systems, but not for Windows. No matter how the Grub Rescue error occurred, you can fix it in a few steps.

1. Insert the Windows installation CD and boot the computer.
2. The system will now boot the CD instead of displaying the Grub Rescue error. Select "System Repair."
3. Wait until the repair is complete. As part of the repair, the boot order will also be set correctly again, so Windows will boot from the hard drive.

Linux and Windows 10 installed

If you have Linux and Windows 10 installed on your computer and get the Grub Rescue error, it may help to put Linux first in the boot order. Boot the computer from a USB stick with the Linux ISO and fix the system. Wollen Sie Windows 10 zum Starten nutzen, kann es helfen, wenn Sie Grub aktualisieren, sobald Sie den Rechner über Linux wieder starten können.
