My computer suddenly shut down a few times when I was using Ubuntu and then I couldn't even boot into Windows or Ubuntu. It's a dual boot computer and I installed Ubuntu from Windows with Wubi.
When I tried to boot into Ubuntu it said that
Errors were found while checking the disk drive for /
I search online and found that the command
mount -o remount, rw /
I tried it but only sometimes it worked and even then the computer then shut down suddenly...
And when it didn't work. The following message was shown:
/host: device is busy
/run: device is busy
/dev: device is busy
But I could boot into Ubuntu once and used boot-repair to generate a report.(Now I can't seem to be able to boot into Ubuntu anymore) It's here.
When I tried to boot into Windows, it just got stuck at the Windows logo screen. And after a while it suddenly shut down.
So based on the report, what's the problem? Is it possible to fix the problem within Ubuntu if I got lucky again and boot into it?
