Linux bir işletim sistemi kurarken live cdde görüntü alamamak

Debian tabanlı Deepin OS kurmak istemiştim. Bootable diskimi oluşturdum ve biostan diski seçerek başlattım. İlk ekran olan "Install Deepin OS" seçeneği önüme geldi. Bu seçeneğe tıkladıktan sonra görüntü gidiyor. Bir daha da gelmiyor. Bilgisayarı yeniden başlatmam halinde bios ekranında görüntü alıyorum, Windows'u başlattığımda görüntü alıyorum, ancak Deepin yüklerken görüntü alamıyorum. Bu sorunu nasıl çözebilirim?

İşlemcim: Ryzen 5 3600x;

Ekran kartım: RTX 2060 Super;

İşlemcim onboard grafik kartına sahip değil. Ekran HDMI ile bağlı, televizyon.

Edit: UEFI değil, CSM ile bootladım. Sorun çözüldü. Bu sefer daha yeni bir sorunum var. Steam açılmıyor. Terminal ile açmaya çalıştığımda aldığım karşılık:

Looks like steam didn't shutdown cleanly, scheduling immediate update check
