What were the results of the bootable Dell Diagnostics you were asked to perform first, with a tutorial provided?
The PW tells us the Active flag is on Recovery but there is no System flag (called Boot in PW) which means we cannot assume the System boot files are intact on the Active partition.
As Archie suggested first run
Partition Wizard Rebuild MBR - Video Help. Then reboot to see if it starts.
If not boot into Win7 installer or
System Repair Disk to run
Startup Repair - Run up to 3 Separate Times with reboots.
That will try to rebuild, repair or if necessary rewrite the system boot files to Recovery partition.
If that fails boot back into PW CD, rightclick on the OS partition to Modify>Set to Active, click OK, then highlight its disk to run Rebuild MBR from Disk tab again. Reboot to see if it starts. If not run Startup Repair again up to 3 separate times with reboots.
If it won't start then there is as possibility it needs disinfection before it can be repaired so start at the top of
Troubleshooting Windows 7 Failure to Start.
If you still need to rescue your files then boot into the installer to copy them to another HD, external or flash stick using
Copy & Paste - in Windows Recovery Console or boot
Hiren’s BootCD 15.1 to copy them out using it's bootable XP explorer. You can also write Hiren's ISO to flash stick using
Universal USB Installer with Hirens in dropdown menu.
I do not have patience with panic or skipping steps. So start at the top of the steps I've given you in both posts and work through them, reporting back results or asking further steps to get each done in an organized manner. If I'm out again Archie or someone else can help you get them done.
