I would suggest you first download a version of a third party partitioning software so you can look at the drive from outside Windows. Gparted is one and
Partition Wizard is another. Download the bootable version so you can burn and then boot to it. If nothing else, make sure either a 100 mb System Restore partition (if you have one) is active, and if not, the Win 7 partition. I am assuming you are not dual booting. Gparted can take a picture of the Disk setup, but Partition Wizard does not have that capability. A digital camera will work, though.....
I suppose there is a chance if you have a special Manufacturers partition, that it might have been used for the system partition. If so, look for a file called bootmgr. That is the partition where the Win 7 boot files are. If it is active, leave it alone for a while.
There have been instances where a manufacturer's installed Recovery Partition has messed with the Win 7 install. Removing that would be up to you since I cannot say for sure it would be necessary.
If you can't get anything else to work, boot back to the repair area and select Command Prompt. Type the following two commands and hit enter after each and wait for a comfirmation from each one before proceeding:
bootrec /fixmbr
bootrec /fixboot
I use these when an XP install messes with the boot. Then reboot and keep your fingers crossed ...
It just seems, since it stops where is does, that it is not finding the Win 7 install.....
