From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What happens with optical drives (lemmy.dbzer0.com)

I’m trying to understand what happens with optical drives in general, and failing.

Backstory: I still have a SATA burner mounted in an expansion bay. I’ve been upgrading my pc for 15+ years and that bad boy is still kicking through all the upgrades. I bought a brand new ssd. When I went to plug it in, I realized I had run out of sata ports on my motherboard. I do have a usb portable optical drive so I really don’t need the old burner. So I unplugged the optical drive and plugged in the new ssd into the same port.

Now I knew something would break upon boot, but I didn’t care - let’s learn. It of course hangs on boot. If I undo the optical drive/ssd swap, it boots fine. Manjaro btw. But what file knows about that optical drive that needs to change? It’s not fstab-that’s just regular hard drives (no opticals listed there). Everything says that optical drives get mounted at /dev/sr0, but clearly something somewhere else needs to be deleted ala fstab file style. But what file?

I tried searching optical drive on the arch wiki and didn’t find what I was looking for with a quick skim (maybe I need to read it closer again)

Anyways thanks!

The boot order is uefi hdd (which I can then pick the hard drive’s boot order in a sub menu), then uefi usb, then uefi optical drive, then network. I don’t think that’s the issue - it should always find something to boot before the optical drive.

I’m going to try the one drive at a time in that first port thing and add/move the rest around. I haven’t been as deliberate with the troubleshooting here as I should have (I immediately went towards a software issue - fstab or something similar). I could have a port / mobo problem. Need to separate software from hardware issue better. Luckily I have three installed operating systems on three drives and plenty of bootable isos to play with. ;)

100%. Keep us updated. I personally love a good puzzle.
