Default [Q] No internal storage

I've searched the forum extensively but I'm still having trouble.

I have a generic em63 android tablet. And yesterday when I turned it on after its battery died I was presented with the initial start up. I found I couldn't install any apps and when I checked the internal storage I was presented with 0.00MB.

A lot of the posts I've found concerned issues caused by flashing the ROM which I haven't or by installing an app to access system files but as I can't install any apps I can't try that technique.

If anyone knows what steps I should take or if there's a thread I haven't found yet that would help anything would be appreciated.
