I just installed Ubuntu 12.10, and I had Windows 7 on my machine. Now Windows is giving me
A disk read error occurred
I can't use my Windows anymore. How do I fix this problem?
I just ran into the same thing. I haven't found the fix yet but I will try the suggestion. However I could boot Windows by using the built in boot menu of my Packard Bell (F12) and choosing the Windows partition directly.
I restored MBR using boot-repair. Thanks all.
