The title of this article is so clearly biased lol.

I tried to make a new account while a VPN was active and it told me to disable my VPN.

This is so disappointing. I am trying to give Valve money, I don’t understand why they disallow this.

No, I was running it from the Steam Deck recovery image on a flash drive. It would consistently say things like “aborted due to error”, whereas it worked instantly with GParted Live. It definitely wasn’t mounted because if it is, it doesn’t even let you make changes.

I found the problem. It turns out that my mistake was trusting KDE Partition Manager. GParted Live worked first time.

If I alter the partition in any way it won’t let me install Steam OS anymore.
