Troubleshooting Windows 7 Failure to Boot - Windows 7 Forums
Did you even run Startup Repair or just the old XP-era Commands?
Run Startup Repair repeatedly after confirming Windows 7 partition is marked Active.
All the steps are in the blue link including disinfecting which cannot be ruled out. Windows 7 would not fail to boot because you disabled an msconfig>Startup entry. Did you delete msconfig>Services without Hiding MS services?
