I am not technical so I have no idea what has happened.
I logged in this morning and everything OK. It said I had updates so proceeded with those but required the core media. I inserted the Mageia 3 DVD but it woundn't mount. So I scanned the internet to see what to do - found a solution. In the meantime I had closed down the upgrade to attempt later. Tried the instructions I found and it worked, I could access the DVD. Went into MCC to get the updates but it now showed there were none to download so I shut down the computer as I had other things to do. I have come back now and I cannot boot it up as it says 'Emergency Mode'. Tried several more reboots but the same result.
Please HELP
