At times I have removed GRUB from the MBR by overwriting the first 446 bytes of the MBR using

|dd if=/dev/zero of=/dev/sdX bs=446 count=1|

|My understanding is removing just the first 446 bytes will leave the partition table, 64 bytes, and the signature, 2 bytes, in tact.
|

|However, I see in the GRUB manual that the boot.img file is 512 bytes.
|

|Wouldn't this boot.img file overwrite the partition table?|
