If it wont startup at all is there a way I can clean install Windows 7 again? But only in to the current Windows 7 drive? and not affect the other partition?

This usually occurs if the drive letter assigned to the Operating system partition in Windows gets changed. When you open explorer with the task manager, check the drive letter for the operating system. It probably is other than C:. Remember it.
Boot to safe mode and then run Regedit and navigate to HKEY_LOCAL_MACHINE/SYSTEM/MountedDevices. Here find the mounted drive (\DosDevices\(Drive Letter)) that is currently assigned the drive letter that you found the operating system was using and change it to C: by renaming the entry (just change the letter).
First, change the \DosDevices\ that is labled C:, to some unused letter.
Reboot to normal.
As always changing the registry can case severe problems if done incorrectly

Whatever the cause may be, I don't think a full reinstall is needed, an in-place upgrade (Win7 over Win7) should do the same = restore the starting point for a successfull installation/activation.

Use Cntrl>Alt>Delete to enter task manager, open explorer to see drive letter. If it has changed use registry fix above.

otherwise....

Try to boot into Safe Mode and run a repair install from desktop. Put DVD in drive, run an Upgrade over itself.

Ctrl+Shift+Esc to enter Task manager.

You can startup Explorer in TM by clicking on;
File > New Task (Run...) > type explorer

Technet page given says error is due to drive changing letters, but I've never seen it before in these move operations. New System drive always stays E: F: Z: whatever.

Use Partition Wizard and see if you can force the letter to C:

But I'm still thinking the catch-all solution is Repair Install. Cross your fingers to get into Safe Mode.

try to run Repair Install. It will fix ANYTHING.

Put DVD in drive and choose Upgrade.

All files, programs and settings are saved. Only need to reactivate afterwards.

So you got to desktop?

If not, try Ctrl+Shift+Esc to get to task manager>Applications tab>New task>enter letter for DVD drive to start DVD

or try this:
