I wanted to wipe out the 64 bit and install the new version with 32 bit later some time. I loaded ubuntu's cd and formated the drive and changed the file system to ntfs cuz i wanted to use the drive in windows for a few days before i installed the new version. Then i successfully returned to windows. Went to windows disk management and reformated it, i MADE A MISTAKE HERE AND ALSO DELETED another drive which was showing .i think it was the swap drive. Then i MADE ANOTHER MISTAKE THAT I HIBERNATED THE WINDOWS. Next time I booted grub tries to load gives 'error 17'.....i tried to reinstall ubuntu to boot my machine but it gives an error cuz i hibernated the windows. What can i do to boot windows. I have a big day in office tomorrow morning. Plz help. Regards, M. Hasan -- Sent from my mobile device </blockquote></div>
