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.
Can you still boot to "Ubuntu"?
If so, start Ubuntu and navigate to GParted. Start it and use the program to check your Windows partition. Often GParted can fix these errors.
Good luck, BTW. You can also use GParted from a live CD/USB.
