rpc error disk management error unable to open dev/nvme0n1p3: device or resource busy
Dell 3070 mini
Also I’m using an additional SSD that I had to manually mount at some point when I installed umbrel. I’m now trying to erase umbrel and anything else and just use startos.

I do not know a lot of the context, but if you are trying to install StartOS on a drive and having this error, you might consider using a linux ( or linux ubuntu live on a usb) and wipe the drive completely formatting it with ext4. Also in your BIOS you might need to disable secure boot. But I am assuming a lot here, I do not know from your post exactly what you are working with or what you are trying to accomplish

This was the main problem I was having:

> Note for those like me that bought a used Dell Optiplex 3070: Mine did not include a drive cage. So I plugged in the SSD to the right port, felt a bit iffy, but it works. For some time, until it is loose enough to slip out of alignment. This blue piece is what I’m missing. [https://www.youtube.com/watch?v=YV8qE894tI0](https://www.youtube.com/watch?v=YV8qE894tI0)
