I don’t see any way to create a community on an instance that isn’t your home instance. If I’m wrong, please give the steps to take.

Thanks for the warning.

This isn’t the Linux/SteamOS boot drive. It’s an SD card. I tell it to boot to the internal storage or the SD card using the option in the Steam Deck BIOS.

Because of this and because it’s a Windows-To-Go install, neither OS should interact with the other’s bootloader. Theoretically.

Linux/SteamOS should just see this SD card as a data drive.

Update: I’m going for it. The only games I have on the SD card I don’t care much about. The other games are on the internal storage. So if this doesn’t work out, I’ll just reformat the card.

I ended up using KDE Partition Manager since it’s included in the Steam Deck Desktop environment.

This is taking a long time. A quick web search says that’s normal. Probably would have been better off just wiping, installing Windows-To-Go, resizing the Windows partition, and then adding a Linux partition.

It’s been over 20 minutes that’s it’s sitting at:
Move the file system on partition 'dev/mmeblkop1 to sector 999,874,560

Edit: 7hrs later and it’s 47% done with that step.

That’s great info. It’ll be so nice when dual boot is officially supported. I wonder if it’s taking so long to roll out because they want to make sure it works well and it’s easy to use.

Final Update:

I could not successfully clone the Windows partition from one card to another.

So I’m wiping the card I’ve been using with SteamOS, and I’m installing Windows-To-Go. Then I’ll shrink the partition. Finally, I’ll add a Linux partition in the empty space. I assume SteamOS will like it just fine.

You probably want to clone the disk. There are lots of guides on this out there. I usually use CloneZilla.

Here’s an Arch article discussing migration (including cloning) https://wiki.archlinux.org/title/Migrate_installation_to_new_hardware

You could say “encrudification” if you’re worried about typing bad words on the internet.

I put “Shazam” into https://alternativeto.net and selected the “open source” filter. Not sure how good they are.
