Grub loader problem

[Haseeb ul Hasan]

I had a dual boot vista with 8.1 ubuntu 64 bit. 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
