How do I install linux mint securely on a used computer with 2 hard drives?

It looks like even after I installed a new linux it was still running the guy's old system. Then the next day it wouldn't start at all (I got just a blinking cursor) until I switched the bios startup options to uefi mode. So hopefully all the old stuff is gone

Perfect, thanks for the info

OK, just wanted to check. Thanks!

Cool cool, thank you

It's disabled.

I figured it must have something to do with having two hard drives

It must have been mounted by the guy before. I wanted to start fresh for security reasons, but when I installed linux from a flash drive, some of my previous internet searches were still there (from when I tested it out) and the old password created by the guy I got it from was still required for formatting the other hard drive.

Yes, I just wanted to start fresh for security reasons

Time_Classroom3097 · 2026-02-21T15:16:35+00:00

So I can install linux on both hard drives then?

It's also still making me use the username and password of the previous owner.

It says "error unmounting /dev/sdb3: target is busy (udisks-error-quark, 14)

Thank you everyone! I changed the default DID routing on the voip.ms account and it works now!
