Does it perform package upgrade? The comments are rather scary:

Hi, I have installed Linux mint 15 with Mint4Win as Dual boot 
with Windows 7.
Then upgraded it to Mint 16 and it was running fine.
But when I upgrade to Mint 17 (Qiana), after restarting the 
partition loop0 (or loopback0 or something like that) fails to 
load.
It shows an error like, Press I to ignore, S to skip or M for 
manual recovery.

Please tell me a way to fix this.
Or let me know if it is not possible.

Looks like my case. Are fstab and mtab replaced during upgrade?
