I recently had a dual boot setup on my laptop with Windows 10 and Ubuntu 19.04. I encountered some issues with Ubuntu and decided to delete it and reinstall it as suggested.

To do this, I deleted the Ubuntu partition using the “create and format hard disk partitions” application on Windows. However, I did not realize that I also needed to delete GRUB, the bootloader that allows me to choose between different operating systems at startup.

I then inserted a flash drive with Ubuntu on it (which I had used previously to install the operating system) and went to the boot menu of the laptop. I selected the option to boot from the flash drive and it booted into GRUB.

However, instead of showing the usual Ubuntu and Windows boot options, it displayed the following message:.

GNU GRUB version 2.02

Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.


What can I do to boot the device into Windows so I can uninstall GRUB and reinstall Ubuntu?
