Dual boot Windows 10 and ubuntu 18.04 problem

I had a dual booted Windows 10 and Ubuntu 18.04 machine.

Last month I decided to uninstall and reinstall ubuntu due to some reasons. I deleted the disk ubuntu partition entirely and I also deleted grub. But somehow when I restarted my computer I was still seeing the grub console. To get out of that I had to type in exit three times to boot into Windows. I followed a guide and tried installing Ubuntu using Unetbootin but I couldn't. On top of that now I couldn't even boot into Windows. Instead, I got an error which said I corrupted the hard drive. Then I installed Windows 8(with a cd) on my machine to access Windows 10. So now I have Windows 8 and Windows 10 on my machine. During boot, I get the windows bootloader screen with 3 options --> Windows 10, Windows 8, Unetbootin.

Now I want too install Ubuntu 18.04 the right way and uninstall Windows 8 from my pc but keep Windows 10 and Ubuntu 18 in dual-boot. Please help me. I am a complete newbie to Ubuntu and Linux.
Thank you very much.

If you have some data to save do it.

You have already deleted Ubuntu partition and you don't want Windows either, so no problem.

Download Ubuntu ISO (and see other options) from here.

Make a bootable USB (see here) or DVD (see Here).

Boot from USB or DVD by selecting the option by pressing F8 or F12. For other kind of computers see here.

When asked choose 'Something else'.

When asked choose the partition to install. So on..

when completed reboot.

Open gparted and delete Windows 8/10 partitions.

Run sudo update-grub

Done.
