3. Find your Linux partition
   Run:

   Look for a Linux partition, like /dev/sda2 with type Linux.

4. Mount your root partition:

5. Mount additional directories:

   sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys


6. Chroot into your system:

   sudo chroot /mnt


7. Reinstall GRUB:

4. Reboot. GRUB will be gone, and Windows should boot directly.

🛡️ Final Tips

• Back up important data before attempting these fixes.

• Make sure you install GRUB to the disk (like /dev/sda), not a partition (/dev/sda1).

• If you’re dual-booting, be careful not to overwrite the Windows bootloader.
