Why it helps:

| Mistake | Consequence | Prevention | |---------|-------------|-------------| | Installing wrong MBR type | System won't boot | Know your OS: XP uses NT 5.x, Win7/10/11 uses NT 6.x | | Changing PBR on wrong partition | Data loss or unbootable OS | Double-check partition label and size before modifying | | Forgetting to set Active partition | Boot device not found | Only one primary partition per disk should be Active | | Not backing up BCD first | Cannot restore original boot menu | Use BCD Editor → before editing |

Choose the specific partition from the target dropdown list. Select the bootloader type matching your OS: For Windows Vista, 7, 8, 10, and 11. NTLDR: For legacy Windows XP systems. Select USB → → Select Grub4Dos or UltraISO

Dedicated entirely to viewing and modifying Windows bootloader configurations.
