There is no NTFS partition in your system. Can you lastly give the output of:

df -h

Thanks

Ok well /dev/sda1 is 8Gb as you said but /dev/sda is 320Gb which is very weird. There is no NTFS partition defined in the output either which is very interesting.

Does the windows OS boot?

no

It does seem that it's very likely there was extra partitions on the disk, but they are gone now. The fdisk output is only showing one disk (sda) and one partition (sda1) so it does not seem to be that windows is on another disk.

My belief is that you may have installed Ubuntu over your Windows 7 install and it is gone now. The best bet would be to try to use a data recovery tool to see whether your old windows files can possibly be recovered.

It looks strange, but it seems Ubuntu was installed at end of your disk. This could mean NTFS partition was removed from partition table, but data are still here. Perhaps if you declare a NTFS partition which use free space before Ubuntu installation, WITHOUT formating, you could get back your NTFS data. And by updating Grub, you could get back Windows boot. It looks weird, but it can work.
