  1. Restart the PC 3 times in a row during startup to enter WinRE (Windows Recovery Environment)
  2. Go to Troubleshoot → Advanced options → Startup Settings → Restart
  3. Select Safe Mode with Networking

If it boots in Safe Mode, the problem is probably a driver or software.

✅ Method 2: Use Startup Repair

  1. From WinRE (as above), go to Troubleshoot → Startup Repair
  2. Let Windows try to automatically repair startup errors

✅ Method 3: Check the disk connections

If you have a desktop PC:

  1. Shut down and unplug the power cable
  2. Open the tower and check the SATA and power cables of the hard drive
  3. Try connecting the disk to another SATA port

Advanced Solutions (If the Above Failed)

🛠️ Rebuild the BCD (Boot Configuration Data)

  1. From WinRE, open Command Prompt
  2. Run these commands one by one:textbootrec /fixmbr bootrec /fixboot bootrec /scanos bootrec /rebuildbcd

🛠️ Change the SATA Mode in the BIOS

  1. Restart and enter the BIOS (usually by pressing F2, DEL or F12)
  2. Look for the SATA Operation Mode option
  3. Switch between AHCI and IDE (try both)

🛠️ Restore the System

  1. From WinRE, go to Troubleshoot → System Restore
  2. Choose a restore point from before the problem started

Only as a last resort. Try all the previous solutions first.
