I was working really happily with Mint Nadia until last week. Brought my laptop to a conference on the other side of the world and just when I needed to do some work, I couldn't get it to function. There was some issue with Dropbox before, which is the only thing that didn't work properly that I can think of. It kept asking indexing everything, no matter what I tried. Don't know how relevant that is though.
At any rate, what I can remember is that my home/Znap couldn't be mounted and I couldn't get it to mount somehow. Sorry if I don't know how to describe it better, because I tried to fix it all jetlagged and tired... In the beginning, I tried changing the boot order, but I realised that my SSD wasn't even visible in BIOS (how strange is that?), which is where my OS runs from. The next morning, pissed off that nothing worked, I saw error message related to RAID, and I decided: rainbows it, I'll try setting it to RAID in BIOS. Big mistake. After that I couldn't even access BIOS anymore to reset it to its previous settings.
Right now, when I turn on my laptop (Acer Aspire S3, if that matters), it very briefly flashes the opening image (with 'Hit F2 for BIOS and F12 for Boot Settings') but I can't access it. Within a few seconds, it just shows a blinking cursor in the top left of the screen.
So, my first question is as follows: how do I regain access to BIOS? And secondly: if I manage to do that, is there a way to get the info you guys need to help me out? It'd be greatly appreciated.
 I use Cinnamon desktop.
