Hi,
According to your picture, you do have a "System Reserved" partition, which is where your boot files are...
Just to be safe, and make sure it is marked as the "Active" (boot) partition, run these commands...
Enter the commands below at the command prompt and hit Enter:
diskpart
list disk
select disk 0 ( or disk with OS\System Reserved)
list partition
select partition # ***Note*** Select the "System Reserved" partition...
active
exit
Then run this from the bootable command prompt also... bootsect /nt60 C: (No Slash)...
Then reboot..
