After using the following commands in windows repair iso:

bootrec.exe /FixMbr 
bcdedit /export C:\BCD_Backup
cd boot attrib bcd -s -h -r 
bootrec /RebuildBcd

The computer starts up asking if I want to run "Windows 7" or "Windows 7", and once it starts up it says that windows is not genuine. I tried using the repair iso and before it opens it gives me the same two options. It says select an operating system to repair

Operating system,Partition Size,Location: Windows 7 Perfessional 152625 MB (C:)Local Disk Windows 7 Perfessional 152625 MB (C:)Local Disk

Its the same thing twice.....

Does anyone know how i can reverse these commands?? ( pic)

Seems like you were using not-genuine Windows with loader-style cracks (probably it was built-in). That cracks create another boot record and make OS load from that second "Windows 7". Try running the second (or both of them), is one of them working? If no, running the same cracker usually helps, but it's illegal and can cause security issues. Buying license key is better. – Jet May 17 '14 at 12:59

Once Windows is loaded, run msconfig. Go to the "Boot" tab. Check to see that the two options listed are really identical. If they are, select one of them and delete it. Restart your computer and it should automatically boot from the only option left. The genuine/activation part you should probably post as a separate question unless it is directly linked to this two entries problem.
