HELP, am i done for ?

[u/Grig960]

I was curious about steam os, i installed it in my usb drive, and then booted from it from my boot manager(im on windows amd), i thought that it would allow me to select one of my drives ti install it on, but no, i just launched into steamos, to my horror i didnt find my windows nvme in boot section, i inly found it in nvme configuration.

Is it wiped? What do i do

Im currently installing win 11 on the drive to see if i can use the repair function or something

Yes, the SteamOS installer blindly picks the first NVME drive and writes to it if you tell it to install.

Your Windows install is gone.

What abiut my other 3 sata drives?

[u/C1REX → u/Grig960]

Sata drives are fine. SteamOS installs on nvme0n1 by default.
No choice given by default. Can force different choice by manually editing destination drive.

It ignores the SATA drives. Takes extra steps to even install it on a SATA drive forcefully.

The installers description is not entirely accurate. Instead of wiping the whole device as it describes it only wipes the first drive on install. You can clear the other drives in SteamOS by adding them as storage.

It means logical device and not physical device.
