I tried to install Ubuntu on my PC so I can run Windows and Ubuntu. I created the Live-USB with Rufus and always got the Errno 5 when I tried to install Ubuntu to my drive. I always deleted the partitions after a try didn't work. I tried everything I found in forums to solve this problem and eventually I recreated the Live-USB with balenaetcher. Now the "Install or try" window doesn't open on startup and if I click on the "Install Ubuntu 20.04 LTS" icon on the desktop nothing happens. I thought maybe it is installed now but all non-windows partions are empty and when I eject the USB stick I can't boot Ubuntu.
I created the partitions for Ubuntu on my HDD. I have a SSD where I start Windows and a HDD where I have all my data. I wanted to install Ubuntu on my SSD but I couldn't create a partition that is large enough because windows doesn't allow it in its partition manager so I tried to install it on my HDD
I did check the md5 hashes and they're exactly the same as on the ubuntu website.
SOLUTION: MY USB-DRIVE WAS CORRUPTED
