Support & Setup Guide

AVL Boot Master · Windows 10/11 & WinPE (UEFI / Legacy BIOS)

1. Getting Started

  1. Download AVLBootMaster v1.0.0.1 (Windows x64) (or AVLBootMasterPE for WinPE) and extract the ZIP archive.
  2. On Windows, launch AVLBootMaster.exe (administrator privileges are requested automatically to access BCD and EFI partitions).
  3. On WinPE, launch AVLBootMasterPE.exe directly — it is statically linked (/MT) and requires no .NET or Visual C++ Redistributable.

2. Keyboard Shortcuts

  • 1 – Create boot entry for WinPE (.wim + boot.sdi)
  • 2 – Create boot entry for Windows (or run bcdboot)
  • 3 / 4 – Backup BCD / Restore BCD
  • 5 – View Raw BCD (bcdedit /enum all /v)
  • 6 / F5 – Refresh BCD stores
  • 7 / 8 / 9 – Backup EFI ZIP / Restore EFI ZIP / Repair EFI from Windows
  • B / R / S – Restart to BIOS / Restart PC / Shutdown
  • F2 / Delete – Rename / Delete selected boot entry

3. Automatic Backups & Safety

  • Before every BCD write operation, AVL Boot Master saves an automatic backup in the Backups folder next to the executable (or in %TEMP%\AVLBootMaster\Backups when running from a read-only WinPE ISO), keeping the 30 most recent snapshots.
  • Any temporary drive letters assigned to EFI or Windows partitions are automatically removed when exiting or rebooting.
