So I've read up on the forum that this is a recurring problem, but this might give just a little more insight.
I installed elementary OS (latest version) on my laptop. The SSD was clean and formatted. When the installation was done, I rebooted and came onto the grub error.
I tried this solution, but it did not work for me. Comment 5 for bug 1492801
When i did do this, I got an error when i tabbed to look for a configfile. it stated:
- hd0 hd1 hd2error: failure reading sector 0xe8adb0 from hd0 and then some more read errors from hd0 and hd2 (hd 1 is swap)
I'm looking for a fix and will update if i do find one.
