I wanted to download ubuntu 20.04 on my old pc, but when I tried to run it from the USB I got an error:unable to find a medium container a live file system
.
Then it starts to ask me to attempt interactive netboot from a URL. If I say yes I have to choose methods of IP configuration and also a url where default one can't be found on the server (https://releases.ubuntu.com/focal/ubuntu-20.04-live-server-amd64.iso).It would then spam about No DHCPOFFERS received.
Is there any way to fix this?
Info: PC: HP Compaq 8200 Elite SFF
Edit:
I have tried to remake live usb 5 times. I've checked the hash of downloaded iso file. I used Rufus to make a bootable USB with iso from releases.ubuntu.com (I have successfully did this with other iso files). I made sure to follow all of the instructions.
