I am new to installing Ubuntu, but I managed to install wubi before. This time I created a bootable usb stick to install Ubuntu from, as explained here. I followed every step and used
D:/ as the USB flash drive.
When I restarted my laptop, the Ubuntu installation menu showed up, but I couldn't select the option:
Try "Ubuntu" or "Install Ubuntu".
When I hit Enter, my machine just restarts and goes back to the Ubuntu installation menu.
Please enlighten me.
