Installed Mint on a brand new Lenovo Z585 Ideapad alongside the pre-installed Windows 8. Everything seemed to go fine, until the reboot, which simply dumped me at a Grub prompt.
I tried the usual ls investigations, but my Mint partition (/dev/sda9) returns an error along the lines of "invalid file name ''." - sorry I can't be more precise right now.
I've booted back into the LiveCD and run boot-repair, which generated the following summary - http://paste2.org/Owy3XNpH.
os-prober recognises my Windows installs (the real install and the recovery thinger), but no Mint.
As far as I can see, browsing the partition through the live cd, the install itself is fine, but I'm more than willing to be corrected. Can anyone help?
Adding the answer in case others have this problem.
Turns out that SecureBoot was in the Security section of the Bios, and not in the Boot section, where I was looking for it.
Disabling it and running boot-repair fixed the problem.
