Issues with migrating from Windows to Linux. Stuck on a black screen with a blinking underscore at top left.

I try to access the virtual console but no keys work alt+f1..f12, alt+ctrl+f1..., I ended up clicking everything on my keyboard but no response other than a sound when I press on a key - the sound confirms my computer can detect keyboard input.

if relevant:

I created a live USB boot via Rufus so that I could install a Minimal Xubuntu OS.

My computer drive only supports MBR, so I chose that.

I chose "BIOS or UEFI" on "Target system" on Rufus

I had no legacy boot option so I opted for UEFI.

I checked no WiFi nor third party software installation like Nvidia.

I would now try to install the third party software, maybe this is a graphics issue. But alas, I cannot do anything on that black screen. Please help, I do not know what to do.
