Can't install Ubuntu (or any Linux distro)

I tried looking up similar questions, but I found no results that solved my problem.

I have a HP-15-bs0xx. It's an old computer and it came, originally, with Windows 10. It doesn't run smoothly on it anymore.

My computer currently has no OS, there's nothing "on" the disk. I erased it accidentally when trying to install Ubuntu (20.4 LTS).

The steps I followed before installing ubuntu were:

1. Downloading Ubuntu desktop 20.4 LTS
2. Verifying the .iso (successfully)
3. Burning the file into an USB, using Etcher
4. Turn off computer, turn on computer, press [esc], choose my USB as the booting device, choose *Ubuntu At this point, a screen loads, saying something around the lines of verifying files. The files are successfully verified.
5. It gives me options of choosing between Trying ubuntu and Installing it. I choose install. (I later tried "Trying Ubuntu", unsuccessfully.)
6. I choose to connect to wifi and install normally the first time around. I try minimal downloads and no wifi the second time. Both times ended with the same result.
7. It tells me that I don't have an OS currently installed, so it doesn't give me option to install along Windows. It only gives me option to make a partition. I don't make a partition, since it seemed unnecessary, given I don't have an OS. I don't understand what happened to Windows, since I never erased it. It just tells me I DON'T have it anymore.
8. The installation begins, it goes smoothly until the "copying files" part, where it freezes for hours.

This happens every time I try, regardless of what I do.

1. I have tried safe graphics
2. I have tried nomodeset and nomodset
3. Legacy mode is enabled
4. When I checked SMART and (short) DST both appear as PASSED

I got NO errors at any point.

Thank you for reading.
