What's bootrec /fixboot?

The [bootrec /fixboot] is a command performed in the Bootrec.exe tool in Windows Recovery Environment. Bootrec /fixboot writes a new boot sector to the system partition by using a boot sector that's compatible with the present Windows system. E.g., if your system is Windows 7, fixboot will write a Windows 7-compatible boot sector and so forth. This fixboot command is normally used to fix a number of startup errors and problems like:

• The boot sector is damaged
• Black screen on startup
• Missing boot device
• Blue screen of death
• Your PC ran into a problem and needs to restart
• Windows failed to start. A recent hardware or software change might be the cause.

In fact, all three situations are pointed to a PC that cannot start properly. One common way to fix such errors is to run the command "bootrec /fixboot".

To run the bootrec.exe, you'll first create a Windows installation media USB flash drive to enter the Windows RE. According to the discussions on Microsoft community, many victims who had the same issue with the command bootrec/ fixboot access is denied, are using the Windows 10 1709 installation media. After they tried the same command with Windows 10 1703 installation media, they do not get the error again.

Alternative Ways to Fix Windows Boot Problems

According to Microsoft, there are several useful commands in Bootrec.exe that are used to troubleshoot the Windows startup problems caused by different locations on a Windows installation hard drive. Besides bootrec /fixboot, which is used to fix the damage to the Windows boot sectors/boot records, the other command bootrec /fixmbris also widely used when there is a problem with the hardware Master Boot Record (MBR). With MBR failure, Windows cannot start either.

Hence, when you must resolve the MBR corruption issues, or when you have to remove nonstandard code from the MBR, use the command bootrec /fixmbr instead of bootrec /fixboot in this case.

Using the fixmbr command in Windows RE is also prone to cause the same access denied issue as the fixboot does.
