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

  • That indicates a problem with the graphics driver. Try to add the boot option nomodeset in the grub menu. Later on you may find a proprietary driver for your graphics card. – sudodus Jun 23 '20 at 19:43
  • If I add nomodeset I get this error and after that all text disappears and the screen stays black until I manually restart my pc. If I instead add amdgpu.dc=0the first error doesn't appear and Ubuntu Live starts perfectly fine though the other errors are still displayed before the desktop appears and I still can't open the installer. If I try to fscksdc3, the terminal says that isuch a folder doesn't exist and also in the Disks application sdc3 doesn't exist. – Poizenes Jun 24 '20 at 05:56
  • So it is not only a problem with the graphics. I'm sorry, but I have no computer with a Ryzen CPU, and cannot help much. Let us hope that someone who knows will see your question and help you :-) -- If you want to check a file sysstem, you should specify the partition as /dev/sdc3 (and in an Ubuntu system with sudo, for example: sudo e2fsck -fc /dev/sdc3 to force checking and mark bad sectors (of partition #3 in drive c) so that they will not be used). – sudodus Jun 24 '20 at 08:17

    I could eventually try another usb drive and now everything works perfectly fine. Thanks for your help – Poizenes Jun 24 '20 at 19:08
