I’m dual booting fedora 28 with Windows 10 and began to like Fedora so much I was thinking about uninstalling Windows completely. First I had to put my steam games on my 2nd drive I like to keep nub SSD for important stuff. I followed a video on how to do it and after doing all of the steps I rebooted and got brought into safe mode. Stupid me figured maybe I messed up so I went in Windows and deleted he partition I made for my games. Still won’t boot instead a black screen comes up saying something along the lines of “ACPI ERROR: METHOD Parse Execution Failed” and then states I am in emergency mode and a start job is running. I think I may have messed up fstab. This was the video.https://www.youtube.com/watch?v=vAgWug72-mQ&t=1s

So you now cannot boot either Fedora or windows 10, is that correct? Can't imagine how copying files from one drive partition to another drive partition would mess up booting. Unless you copied to the wrong drive??. I don't see how deleting the partition on the second drive would prevent booting on the other drive. I did not watch entire video but he seemed to know what he was doing. You didn't happen to keep notes of the steps you took?

I doubt if the acpi errors are relevant at all. They happen all the time and are really just warnings. A corrupt root partition due to an improper shutdown sounds more likely. The first thing I would do in this kind of situation would be to boot from the installation disc and run fsck on all the partitions.

I gather too from googling that Fedora sometimes does this when there are automountable partitions listed in /etc/fstab that can't be found. It's probably a systemd thing, because systemd uses fstab to create its runtime mount service files. op says he created a partition and then deleted it, but doesn't say if he made an entry for it in fstab. Another thing to check maybe.

Sorry guys I accidentally posted this twice it's fixed now I had to boot on the live usb go into a live usb, gain root access to fstab which was hard for a noobie and then edit out the lost partition.
