New guy here, just getting my feet wet with Linux.

I have a windows 11 PC, and used Ubuntu´s online guide to install a bootable USB.

Booting the USB, I had options, to install the OS or to try it. So I installed it, alongside my windows 11.

All is fine, but I decided to go back into windows and delete the partition for Ubuntu because i wanted to start again a fresh with bigger size dedicated.

However, in booting, I now come to some scarey black screen about grubs and I cant seem to do anything.

Restarting the PC, I get into boot manager and boot to windows, no problems. All is well. But each time I boot, I hit this black screen - I want to remove it before I give Ubuntu installing a second go.

Suggestions welcome!!

You may have removed the Ubuntu partition from your hard disk, but the Grub Bootloader (the software which asks you which OS you want to boot Windows/Ubuntu every time you boot your PC) still exists in your EFI partition, which is why you're seeing the scary screen when you boot up.

To fix this, you need to access your BIOS settings and change the boot order to prioritize the Windows bootloader over the Grub bootloader. The trick to enter your BIOS settings depend on your Computer hardware. If you use a laptop you can google "how to enter BIOS setting in {your laptop model name}"

You can use this video as a tutorial on how you can make Windows Boot Loader default again.

But let me tell you that even if you plug your usb while booting, and install Ubuntu all over again without changing the bootloader, you can change the size of the Ubuntu system and Ubuntu will configure the Grub screen once again for you. So you'll get the option to choose between Windows and Ubuntu again. So my suggestion is to reinstall Ubuntu again and not mess with the bootloader.

And given that you're new to Linux and dual booting in general, I would suggest you to not try to remove Grub without understanding what you're doing or else you may mess up.
