Just installed Antergos Gnome edition on my box. I have 4 hdd installed, the root partition is /dev/sda1 according to the install, but when the install finishes and I reboot, /dev/sda1 is now dev/sdb1 and therefore I get a grub error on boot.
I know how to fix this, I did it when the same box had Debian installed, but when I run ls (hd1,1) I get unknown filesystem error. I should point out that all drives are formatted as EXT4, and some like (hd0,1), (hd0,2) and (hd0,3) actually list their contents when I ls them, but the drive with my root partition and was set as my boot partition give the error unkown filesystem.
To add to the confusion, if I keep the Antergos minimal install CD in the drive and I select Boot from Hard Disk, it boots correctly!!!
Any help gratefully recieved.
