Bootrec, also called bootrec.exe, is a tool provided by Microsoft that you can use in Windows RE (Recovery Environment) to troubleshoot and repair a master boot record (MBR), a boot sector, and a Boot Configuration Data (BCD) store. You can learn about common bootrec prompts from the list as follows:
- bootrec/ fixmbr: This command will write an MBR compatible with your computer to the system partition. It will not overwrite the existing partition table. You can use this command when you have to repair a corrupted MBR or when you have other MBR issues to resolve.
- bootrec/ fixboot: It will write a new boot sector to the system partition by using a boot sector that’s compatible with your computer. You should run the command when the boot sector is damaged or replaced with a nonstandard boot sector.
- bootrec/ scanos: This command will scan all disks for installations that are compatible with your Windows. Meanwhile, it will also display the entries that are currently not in the BCD store. Use this command if there are Windows installations not being listed in the Boot Manager menu.
- bootrec/ rebuildbcd: It will scan all disks for installations that are compatible with your Windows. At the same time, it allows you to add the installations that you want to the BCD store. Use this command when you have to rebuild the BCD store completely.
If there is something wrong with your Windows 11 startup, you can run the bootrec to repair the errors that prevent your computers from starting.
