FreeDOS help system (hhstndrd 1.0.8 en)[bootfix]

Command: bootfix

BOOTFIX is a boot sector testing and fixing tool.


BOOTFIX [/d] [drive] BOOTFIX [/?]


drive The drive letter you wish to check and possibly fix, e.g. C: /d Displays information on screen about the boot sector, including a hexadecimal readout. /? Shows the help.


The boot sector and the master boot record (MBR) are very important parts of the FAT filesystem. They are created by fdisk and sys. If something is wrong with the boot sector, the whole partition cannot be read. If something is wrong with the master boot record the OS (FreeDOS) cannot boot at all.


bootfix c: bootfix /d c: >dump.txt Will dump the information to a file called dump.txt
