We recently had a power outage in the office and one of our ubuntu servers isn´t booting up properly. Here is what I have deduced so far:
- The motherboard seems fine and it allows me to enter the BIOS / UEFI settings.
- The only gurantee I have regarding the power source is that, again, it lets me see the UEFI settings and...
- I can boot a live USB with Ubuntu Desktop in order to trouble shoot a little more
- The SSD still has all the information intact. I have connected it to an ubuntu desktop machine and saw that it is all still there...
- When I simply restart the machine I´m faced with a dark screen (The pixels are on, but they´re black)
Where do you reckon I should look into next? I´m thinking it could be an issue with GRUB, but I´m not too sure.
EDIT: Ended up being the motherboard. For some reason there was a setting that would only allow for Windows boot manager to show. As soon as I deselected the option I was able to boot ubuntu with relative normality. I know this ended up not being ubuntu's fault but I'm just going to leave this up as it is since it might be helpful for someone else in the future.
I ended up changing the setting called "boot mode" or something similar to that. I am the one of five people who have physical access to the server and I really doubt someone else would have touched it, which seems really odd. The setting only had two options: - Windows mode - Other OS
I found it extremely odd since I was also able to boot up other OS's using a USB stick and while this was set to "Windows mode". I think it's always been like that.. I turned off Secure boot and changed this weird setting to "Other OS" and after that it just booted up normally. This was an Asus motherboard by the way.
