I just turned on my PC where I'm dual-booting Ubuntu and Windows 8 and I had the following message at startup:
Invalid video mode 'text'
Booting in blind mode
Fortunately for me the laptop booted up fine anyways in blind mode and I was able to log in, however I've googled around and it turns out that this is an issue with Grub and it can be more serious in some cases.
Any idea on how to fix/correct this in a safe manner? Or what could I do to check that my Grub doesn't have any issues?
I found out what the problem was, apparently it has something to do with having Legacy Grub rather than Grub 2. Not sure whether is was UEFi that wasn't playing nice with it, but updating Grub to Grub2 using the following steps solved this issue and my laptop boots normally without the message:
sudo apt-get install grub-pc
<OK>
before pressing enter once done.Once I checked that all my Grub entries worked correctly in Grub2 by rebooting to test each of them I upgraded Grub to Grub2 using
sudo upgrade-from-grub-legacy
in a terminal window.I'm not sure if this is just a workaround but at least my problem seems to be solved for the time being.
