I just upgraded to 12.10. After installing the files and rebooting I had come across following problem:

error file not found

grub rescue> _

This problem was easily solved by repairing the boot using Boot Repair tool. This answer helped me.

But after this, Windows won't start. It's giving following error:

A disk read error has occurred

Press Ctrl+Alt+Del to restart

enter image description here

How do I fix this?
