Use Advanced Boot Options to Launch Startup Repair in Windows 7
If your computer doesn’t show you the Windows Error Recovery screen, you can manually launch Startup Repair by following these steps:
Turn on your computer.
Press and hold the F8 key.
You will see the Advanced Boot Options screen. Choose “Repair Your Computer” to run Startup Repair.
Sometimes, the Startup Repair option may not be available, and you’ll be asked to use a Windows installation disc to repair your computer. In this case, you can create a Windows 7 recovery USB to repair your Windows 7 computer.
Create a Windows 7 Repair Tool to Troubleshoot Windows 7
To create a Windows 7 repair tool, you’ll need three items: an ISO image file, a USB flash drive (at least 4GB), and the Windows 7 USB/DVD Download Tool. Follow these steps:
Plug your USB flash drive into your Windows 7 computer and ensure it can be detected. Run the Windows 7 USB DVD Download Tool and click “Browse” to choose the ISO file.
Select “USB device” as the media type.
Select your USB drive from the drop-down menu and click “Begin Copying” to start the media creation process.
Remember to back up important files on the USB drive first, as it will be formatted. Wait until the process finishes, and you’ll have a Windows 7 recovery USB drive that you can use to launch Startup Repair.
If Windows 7 startup is still not working, you could try other recovery options, such as System Restore.
