MBRWizard Suite FAQ

+ I think I have a boot virus, how can I remove it from my computer?
Since a boot virus is stored in the Master Boot Record, we simply need to replace the infected code with the original MBR information. Using the MBRWizard Suite, the process is as simple as selecting the infected disk and pressing Repair to restore the original boot code. Note, this process will not change the partitions or disk signature on the drive. See example

This ISO may be burned to CD/DVD and used to boot up the computer for offline troubleshooting and repair. See WinPE for more information.
+ How do I fix my Windows 7 master boot record?
The Repair option is designed to replace the boot loader on the disk with a standard Windows boot loader, and supports both Windows 7 and Windows XP formats.
  • GUI version: After selecting the target disk, select the Repair option, click the desired version of MBR and click Repair. See example
  • CLI version: Available parameters are xp or win7. The following example will repair a Windows 7 MBR on the first disk:
    mbrwiz.exe /disk=0 /repair=Win7
+ How can I use MBRWizard to make my flash disk bootable?
Most flash drives come from the manufacturer formatted as a Superfloppy rather than with an MBR. In order to make a flash drive bootable the disk should first be converted to MBR, which can be accomplished with the Repair function of MBRWizard. Once the MBR has been established, a standard NTFS or FAT partition can be created, formatted, and set as Active (bootable), leaving only the need to copy the operating system to the newly prepared disk.
There are a few different methods for creating a bootable flash disk, see the following instructions:
  • After selecting the flash disk to use from the available disks, click the Partitions button, now click the Create button to open the partition creation Window. Leave the default sector alignment value at 128 (64k), and click Create partition. This will only take a moment, but the disk is now ready to be ejected, reinserted, and formatted.
  • After selecting the flash disk from the list of available disks, click the Repair button, select the Windows 7 type of MBR and click Repair. Eject and reinsert the disk, once detected a bootable partition can be created and formatted using Windows disk management, or another similar utility. Make sure you come back to MBRWizard and make the partition active by highlighting the newly created partition and clicking Active (boot). Click Apply Changes to save.

If the flash disk is already formatted as an MBR type disk, see the section below entitled, "How do I select and set a partition as bootable?"
+ How do I write a new disk signature value of AD69AD69 to disk 0?
GUI version: Select disk 0 from the list of available disks, now click Disk Signature to view the available signature options. Simply enter the new 8 digit hexadecimal value of AD69AD69 in the available field and click Save.
CLI version: Using the /signature=write command, the following will save the new disk signature to disk 0:
  • mbrwiz.exe /signature=write /value=AD69AD69 /disk=0
+ How do I select and set a partition as bootable?
GUI version: Select the disk containing the partition you want to set active, click on Partition to view the available partitions. Now click on the desired partition, check the Active box, and click Apply changes to set the partition as bootable. See example
CLI version, see the following example:
  • Set the first partition on the first disk bootable: mbrwiz.exe /active /disk=0 /part=1
*Note, only a single partition may be bootable at a time.  The process of setting a partition active will set all other primary partitions as inactive.
+ How can I view the structure and details of my hard disks and partitions?
GUI version: Once the desired disk has been selected, a Disk Details button will be displayed, which shows the details of the MBR, disk, and specific partition information. The complete disk and partition information may also be printed for emergency situations by clicking the Print button. See example
CLI version: Use the /list command to display details, ie. mbrwiz.exe /list
+ How do I delete one or more partitions from a disk?
Deleting a partition removes all references from the MBR, and effectively deletes all data contained on the partition.
GUI version: After selecting the desired disk, click the partition button to list available partitions. Select the partition to delete, now check the Delete box and press Apply changes to delete. See example
CLI version, see the following examples:
  • Delete the first partition on the first disk: mbrwiz.exe /disk=0 /part=1 /del
  • Delete the third partition on the second disk: mbrwiz.exe /disk=1 /part=3 /del
+ How can I view the contents of an MBRWizard backup file?
GUI version: After selecting the desired target disk, click the Restore button and select the backup file, under which the the file contents will be displayed. See example
CLI version: use the /show=file command, ie. mbrwiz.exe /show=file /filename=d:\MyDisk1MBR.mbw
+ How do I sort the partition entries in the MBR?
GUI version: After selecting the desired disk, select Partitions and click on Sort Entries.
CLI version: Use the /sort command to sort the partition entries by physical location on the disk. ie. mbrwiz.exe /disk=0 /sort
+ How do I change the partition type identifier of an existing partition?
In some circumstances the partition type identifier located in the MBR may get modified. The following describes how to modify the partition type identifier (Note, this will NOT convert the file system, only change the identifier in the partition table).
GUI version: After selecting the desired disk, click on Partitions, select the partition to change, then click on Change Type. Select the desired type from the list, click Ok, and finish by Applying changes.
CLI version: The following will change partition one (1) to type NTFS (7): mbrwiz.exe /part=1 /type=7
+ How do I reinitialize, or wipe the MBR clean?
Wiping the MBR can be used in situations where you want to completely remove the MBR, or perhaps all data and partitions from the disk. In addition to the MBR, MBRWizard also supports wiping the first Track, the GPT, and the entire disk.
GUI version: After selecting the desired disk click on Wipe, select MBR (or another option), then click on Wipe.
CLI version: See the following examples:
  • Wipe the MBR on the first disk: mbrwiz.exe /wipe=mbr /disk=0
  • Wipe the entire first head on the second disk: mbrwiz.exe /wipe=track0 /disk=1
  • Wipe sectors 2 through 12 on the third disk: mbrwiz.exe /wipe=2-11 /disk=2
+ How do I run the CLI version of MBRWizard under Windows?
If installed as part of the MBRWizard Suite, simply select MBRWizard CLI from the Start menu and a command prompt window will be automatically created and ready to run. Simply type mbrwiz /? to get started.
For direct downloads of the CLI version, uncompress the zip file and copy the contents to a location on your hard disk, for example C:\Windows\System32. Now, click on Start->Run, Type 'CMD' and press 'Ok', this will bring you to a command prompt. You can start MBRWizard CLI by typing 'mbrwiz.exe, make sure you check out the available options from the CLI Reference page for specific functionality.
+ Why does MBRWizard show my SATA disk as a SCSI device?
A SATA disk frequently shows up under Windows as a SCSI device when running in AHCI mode, or when connected via certain storage controllers manufactured by Silicon Image, JMicron, and NVIDIA nForce. This is normal even though this isn't a SCSI disk, and does not affect drive performance.
+ Why should I backup my MBR when I can just repair it if something goes wrong?
The MBR actually contains the following multiple components:
  • Boot record- the code required to bootstrap the computer
  • Partition table- contains the location, size, type, and other information about the partitions on the disk
  • Disk signature- A unique value which assists Windows in identifying the disk, used mainly for reassigning drive letters
The Repair process returns the boot code to a default state provided by the specific version of operating system, but would leave the partition table untouched. A loss or corruption of the partition table would effectively remove the partitions on the disk, including all information such as documents and pictures. Capturing a quick backup of the MBR each time a partition is resized, deleted, or added will make sure the partition table can be restored.
+ I get MBR Error 3 when starting up Windows 7, but then Windows starts and run fine. Can MBRWizard fix this?
MBR Error 3 typically indicates some corruption in the Master Boot Record, which is quickly resolved using MBRWizard. From the MBRWizard GUI simply select the hard disk on which the problem is happening, then click on Repair, select the Windows 7 MBR format, then apply changes. The machine should now boot without the error message. See example
+ Why do I get error code 2755 when trying to install MBRWizard?
Error 2755 is actually a Windows installer error, and is caused when the .msi install file is located on an encrypted disk or folder. Simply copy this file to a non-encrypted location, such as USB flash drive, and install from this new location.
+ MBRWizard is reporting error 506, what does this error mean?
Error 506 indicates a failure attempting to read a given sector from the selected disk, typically due to a bad sector or failed disk. Make sure you immediately backup all critical data from this drive if you see this message. Once the contents are backed up, try running the disk utilities from the drive manufacturer (SeaTools for Seagate, Drive Fitness Testfor Hitachi, Data Lifeguard for Western Digital, etc) in order to identify any potential drive problems.
