Postup řešení

  1. 1 Boot from your Windows 11 installation USB. When the setup screen appears, click 'Repair your computer' in the bottom-left corner. This takes you to Advanced Startup.
  2. 2 Go to Troubleshoot → Advanced Options → Command Prompt. This gives you access to repair tools.
  3. 3 In the Command Prompt, type 'bootrec /fixmbr' and press Enter. This repairs the master boot record, which is the first thing the PC reads to start Windows.
  4. 4 Type 'bootrec /fixboot' and press Enter. This repairs the boot sector, which tells Windows how to load.
  5. 5 Type 'bootrec /rebuildbcd' and press Enter. This rebuilds the Boot Configuration Data (BCD), which contains the list of operating systems. Follow the prompts to add your Windows installation.
  6. 6 If that doesn't work, check your BIOS settings. Restart your PC and press Del, F2, or F12 (depending on your motherboard) to enter BIOS. Look for SATA Mode or Storage Configuration and try switching between AHCI and IDE (or RAID). Save and exit. This can fix driver incompatibility.
  7. 7 If you recently cloned your drive, ensure the new drive is properly connected and recognized in BIOS.
