Using Windows 7 Installation Disc/USB:
- Insert your Windows 7 installation disc or bootable USB drive.
- Restart your computer and boot from the disc/USB.
- Select your language and keyboard layout, then click “Next.”

-
Through Advanced Boot Options (If You Can Access Windows):

Common Command Prompt Commands for Windows 7 Repair
Once you’re in the Command Prompt, you can start using various commands to repair Windows 7. Let’s explore some of the most effective ones:
1. Bootrec.exe: Repairing Boot Problems
The Bootrec.exe tool is your go-to solution for fixing boot-related issues. Here are some essential commands:
-
bootrec.exe /fixmbr: This command writes a new Master Boot Record (MBR) to the hard drive, which can resolve issues with a corrupted or damaged MBR.
-
bootrec.exe /fixboot: This command writes a new boot sector to the system partition, often necessary if the boot sector is damaged or an incompatible boot sector is installed.
-
bootrec.exe /rebuildbcd: This command scans all drives for Windows installations and allows you to rebuild the Boot Configuration Data (BCD) store, which can fix problems with missing or corrupted boot entries.
2. System File Checker (SFC): Repairing Corrupted System Files
Corrupted system files can lead to various errors and instability. The SFC tool scans for and replaces these corrupted files with healthy versions.
- sfc /scannow: This command initiates a system scan for corrupted system files. If any are found, they’ll be automatically replaced from a cached copy.
3. CHKDSK: Checking and Repairing Hard Drive Errors
Hard drive errors can cause system crashes, data loss, and other problems. CHKDSK scans your hard drive for errors and attempts to repair them.
- chkdsk C: /f /r: This command checks the C: drive (replace with the drive letter of your Windows installation if different) for errors and attempts to repair them (/f) and recover readable information from bad sectors (/r).

-
Note Down Error Messages: Pay close attention to any error messages that appear during the repair process. These messages can provide valuable clues about the problem.
