Fix Grub Rescue "error in Windows 10 - Here's how
If you can no longer start Windows 10 and only the "Grub Rescue" display appears, there is probably an error with the Linux boot manager Grub. We'll show you how to fix it.
Fix Grub Rescue error when Windows 10 won't start
Grub is a boot loader that is mainly used for Linux systems. If the computer shows you the message "grub rescue>", instead of booting Windows 10, you have to repair the boot loader.
- Obtain a copy of the Boot Repair Disk program.
- Run the program and follow the instructions. For this you need a USB stick, the content of which may be deleted.
- Eject the USB stick and connect it to the faulty system and start from the USB stick.
- Make sure that your computer can boot from USB.

Fix Grub Rescue errors outside of Windows 10
When the Grub Rescue error shows up, someone tried to install Linux on the faulty system. An error must have been made. The Boot Repair Disk starts a Linux live system to fix the error. It is recommended that you connect to the Internet via cable at this step.
- Select "Recommended repair".
- Follow the instructions of the program. You will be asked to open a terminal and enter some commands. You can reach the terminal via "Accessories"> "LXTerminal". You will reinstall Grub during the guided troubleshooting.
- After the new installation, you will see a URL address that you should write down. Provided that you have an Internet connection, you can get information about boot errors there.
- Reboot the system and select "Windows 10" from the Grub menu to boot Windows 10.
Bugs still not fixed: help from support
If the boot repair disk was unsuccessful, you can provide the noted URL address in a forum for further help. If you are using a dual boot with Linux, it is worthwhile to search in the appropriate forum. You can find some Linux forums for the respective distribution here:
- Ubuntuusers.de for Ubuntu-Linux
- Archlinux.de community for Arch LInux
- Fedora Forum for Fedora Linux
- Debianforum.de for Debian Linux
- You can find more distributions using the search engine or (mostly in English) on distrowatch.com on the right page for your distribution.
