Enable Safe Graphics

[Infinimonster]

Hi, yesterday i posted this Thread here: https://forum.proxmox.com/threads/c...ssue-flashing-screen-after-first-step.127154/
I got an answer that i should boot in safe graphics mode so i googled about it but couldn't find anything useful.

Anyone knows how i can boot with safe graphics?
