I've decided to use my laptop to dual boot Ubuntu alongside Windows 10, but I've ran into several issues. I used a USB removable device to install Ubuntu. I noticed that, during the installation, it doesn't recognize Windows 10 at all, so I made the probably very stupid choice to overwrite all my existing data completely.
It would've been all good if I didn't get a fatal error during the installation concerning the bootloader. I tried to boot Ubuntu after the installation nonetheless, and it brings me to a black screen that briefly says "Checking media" and afterwards shows nothing but a flashing underscore. I assume that in the current state, Ubuntu is unbootable.
I try reinstalling, and get no fatal error this time, but the end is the same - seemingly unbootable state.
Lastly, I press the "Try Ubuntu" option to see if I can install grub2 manually, but I don't get access to Wi-Fi. What am I supposed to do?
