Installed ubuntu 11.04 on a Amd 64 machine already have a win7. After installation completer, book into ubuntu is ok. When select win7 from boot menu, it occors:
"A disk read error occured. Press ctrl alt del to reboot."
Should there method to recover it besides reinstall win 7? Tried run win 7's boot recovery from installation CD, not success. Tried sudo update-grub, not ok.
Thanks.
