Just a little theory about booting.

The BIOS will hand over execution of code to the MBR of the boot device. 
If the MBR is a windoz based MBR, it will look for a active primary 
partition and hand over the execution to the code in the boot record of 
the active partition. In your case it looks like this is grub in the 
/boot partition.

If you now choose to boot windows, grub will hand over the execution to 
the code in the boot record of the windoz partition. This code starts, 
but gives you the error "NTloader missing".
I don't think you lost the NTloader in your NTFS partition (it is in the 
root of the C: drive), but there is something  which the windoz boot 
code does not like. Maybe it is checking if the NTFS partition is set 
active and if not gives you this error? Or checks if more than one 
partition is active?
It could also be that your windoz boot code is corrupted again. It was 
after your last installation. Did you try to run fixboot from the 
windows recovery CD?

You can try to only set the NTFS partition active and if you have still 
the windoz code in the MBR it should right boot into windoz. If you get 
the same error, the boot code of the NTFS partition is corrupt -> run 
fixboot.
