Fix your booting problems with MbrFix.exe

Usage:



MbrFix /drive {/partition } { /yes } { /byte }

Requirements:


The program is made for Windows NT, Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7 and Windows PE. Both 32-bit and 64-bit x64 editions are supported.

You need administrative privileges to make it work!

Purpose:


Perform several Master Boot Record (MBR) tasks, like backing up, restoring, fixing the boot code in the MBR, etc. The utility should not be used for GUID Partition Table (GPT) disks. The utility now, by popular demand, also come in a x64-version running unde x64-editions of Windows and PE.

Commands:


MbrFix /drive driveinfo Display drive information


MbrFix /drive drivesize Returns drive size in MB as return value


MbrFix /drive listpartitions Display partition information


MbrFix /drive savembr Save MBR and partitions to file


MbrFix /drive restorembr Restore MBR and partitions from file


MbrFix /drive fixmbr {/vista
/win7} Update MBR code to W2K/XP/2003, Vista or Win7


MbrFix /drive clean Delete all partitions on the selected disk


MbrFix /drive readsignature {/byte} Read disk signature from MBR


MbrFix /drive writesignature Write disk signature to MBR


MbrFix /drive generatesignature Generate disk signature in MBR


MbrFix /drive readstate Read state from byte 0x1b2 in MBR


MbrFix /drive writestate Write state to byte 0x1b2 in MBR


MbrFix /drive readdrive


Save sectors from drive to file


MbrFix /drive /partition fixbootsector


Update Boot code in boot sector


MbrFix /drive /partition getpartitiontype


Get partition type


MbrFix /drive /partition setpartitiontype


Set partition type


MbrFix /drive /partition setactivepartition


Set active partition


MbrFix /drive getactivepartition Get active partition


MbrFix volumeinformation driveletter Get volume information for partition


MbrFix flush {driveletter(s)} Flush files to disk for partition


MbrFix listpartitiontypes List partition types

Drive numbering starts on 0.


Partition numbering starts on 1.

Commands restorembr, fixmbr, generatesignature, writestate, clean, setactivepartition and fixbootsector will ask for confirmation unless /yes is included. All these commands may lead to data loss if used incorrectly or without intention.

If the /byte option is given for the readsignature command, the signature is returned as a byte array instead of as a DWORD. Writesignature requires the new signature to be specified as 8 hex digits.

If /vista is used with the fixmbr command, a Windows Vista MBR is written, if /win7 is used, a Windows 7 MBR is written instead of the default Win2000/XP/2003 MBR. The Vista or Win7 MBR should work with the other OS'es.

When fixing boot sector of a chosen partition, the wanted OS version must be specified. For now, the only valid choices are WIN98, DOS5 and DOS6.


The purpose of the fixbootsector command is to insert boot code for loading DOS from a partition created and formatted as FAT using the Windows 2000/XP/2003 tools, since those tools inserts boot code for loading NTLDR.
Return codes:


The program reports an errorlevel as 0 for OK and other values for errors.


The exception to this is the ReadState, GetPartitonType and GetActivePartitions command which returns the state as a return code as well as printing to stdout. Any errors for this command are returned as negative values because of this. The DriveSize command returns the drive size in MB, and 0 in case of error.

Why do I need this utility?


Well, I was testing Windows Embedded XP using a virtual PC, and was booting Windows PE from a CD-ROM to partition a brand new harddisk (quite cheap, since it was virtual !). Using the diskpart.exe utility (found in Windows XP and Windows Server 2003, available as a download for Windows 2000), I created the partition, made it Active, assigned it a drive letter. I then used the format.exe utility to format it to NTFS (format C: /fs:ntfs).

DISKPART> detail part


Partition 1


Type: 07


Hidden: No


Active: Yes



Volume ### Letter Lable Fs Type Size Status Info.


---------- --- ----------- ----- ---------- ------- --------- --------


* Volume 1 C WinXP NTFS Partition 149 MB OK System

I then mounted a network drive to my physical computer and copied the boot.ini, ntldr, ntdetect.com, windows folder, program files folder, etc. from the Windows Embedded XP image directory. Everything to make it boot.
Well everything should be OK, so I rebooted the (virtual) computer and expected it to boot up Windows Embedded XP.

But not so! It just sat there with a nice black screen. No error message at all.

Some investigation later on the Internet, I found this very informative page by Daniel B. Sedory: http://thestarman.narod.ru/asm/mbr/index.html, containing a wealth of MBR info. The info on one of the pages states that the MBR code is installed on the drive when the Windows setup program runs and no MBR code exists already. Hmm.., seemed to be right on the mark.

I searched further on the Internet, but the only utilities I found which could install MBR code was for other operating systems, like FDISK.exe /MBR for DOS (but I wouldn't boot to DOS...) or the fixmbr command in the Windows 2000/XP/2003 Recovery Console. Didn't want that either. Wanted something to work on a Windows 32 bit platform, to be able to fix the problem in other cases when using Win PE and just plain copying in the operating system files. So, then I was left to make the utility myself!
Problem solved: After booting up Windows PE from CD again, the command MBRFix /drive 0 fixmbr /yes solved it all. Embedded XP booted like a charm.
Samples:
C:\> MbrFix /drive 0 listpartitions
# Boot Size (MB) Type
1 Yes 151001 6 DOS 3.31+ 16-bit FAT (over 32M)
2 1623 12 WIN95 OSR2 32-bit FAT, LBA-mapped
3 0 0 None
4 0 0 None
C:\> MbrFix /drive 0 savembr Backup_MBR_0.bin
C:\> MbrFix /drive 0 restorembr Backup_MBR_0.bin
You are about to Restore MBR,
are you sure (Y/N)? Y
C:\> MbrFix /drive 0 fixmbr /yes
C:\> MbrFix /drive 0 fixmbr /vista /yes
C:\> MbrFix /drive 0 /partition 2 fixbootsector WIN98 /yes
C:\> MbrFix /drive 0 /partition 2 setpartitiontype 14 /yes
C:\> MbrFix flush (flush all drives)
C:\> MbrFix flush cde (flushes C:, D: and E:)
C:\> mbrfix readsignature
C:\> mbrfix writesignature 473d4f07

Readstate and Writestate:


The commands readstate and writestate use a byte at offset 0x1b2 to store state. This was changed from offset 0x1b0 used in earlier versions to be compatible with Windows Vista MBR. These commands are only useful in a scenario where you use Windows PE to roll out other MS operating systems, and you have no other place to store information about where you are in the installation process. This location in the MBR is unused as far as known, from the days of DOS 3.30 until Vista.

Change permission of all the files at once in windows 7

Well migrating from XP to windows 7 it is a huge pain to work with files sometimes,because the permission of the files changed automatically and and need to be changed to be used properly,taking the ownership of the file also help,but I didn't know how to change the permission of all the files at once as whenever you select multiple files and right click on them the security bar do not appear unlike XP,here is the 2 command that can do the job for you(for me the last one worked like a magic).

Use takeown from the command prompt to take ownership a folder and all subfolders & files recursively:

takeown /f "c:\folder\subfolder" /r

You can use CACLS from the command prompt:

cacls "C:\path\to\folder" /E /T /C /G "Administrator":F

The /T switch allows it to function recursively. Replace Administrator with the user you wish to give permissions to.

Restore the Cisco IOS to a router

Have you ever accidentally wiped out the IOS on your router?If you're working quickly and not paying attention, it can be an easy mistaketo make. All it takes is making a typo in the destination filename when you'retrying to save a change.

Here's an example:

router# copy running-config startp-configDestination filename [startp-config]? Erase flash: before copying? [confirm]Erasing the flash filesystem will remove all files!
Continue? [confirm]

Hitting [Enter] a couple of times out of habit can all tooquickly wipe out the IOS. If you don't realize the mistake in time, rebootingthe router means the IOS is gone for good, and the router won't boot up.

Losing the IOS can also happen when upgrading the flash onthe router. As the Cisco IOS grows larger, having to upgrade your flash is a verycommon task. But when you install the new flash, it has no IOS, leaving you inthe same position as if you had accidentally erased the flash.

Unfortunately, if you're like many people, when you wipe outthe IOS, you may not have a backup copy of the IOS. Or, you may not have accessto the Cisco IOS download site or have the time to download the somewhat largeIOS file.

And if you're looking for the same IOS on all of yourrouters, it can be difficult to locate it on the Cisco IOS download site. Manytimes, it's much easier to take the IOS from an existing router and restore iton the router that's missing its IOS.

Let's look at the step-by-step process for restoring theCisco IOS to a router using this method.
Install a TFTP server

First you need to install a (TFTP) server. I recommend theTftpd32 server, which you can download from theWeb. This is a great TFTP server, without a lot of the fluff that most ofthe others have. At less than 1 MB, it's very small and has no installapplication.
Run the TFTP server on a PC

If you've just pulled the working router off a shelf, youcan connect the PC to the router with a reverse Ethernet cable. Configure therouter and PC on the same network. Make sure that you can ping the router and thatthe router can ping you.

If your working router is up on your network, you can just downloadthe IOS over the network directly using instructions in the next section.
Copy the IOS from the working router to the PC

Here's an example of how to accomplish this:

copy c2600-12-3.xxxx.bin tftp://10.253.15.72

Replace 10.253.15.72 with the IP address of your PC, andreplace c2600 with the name of your IOS. (You can locate the name of the IOS onthe working router using the show flashcommand.)

This saves the IOS on the PC in the directory configured bythe TFTP server. Figure A shows anexample of what it looks like while downloading. Make sure to note thedirectory in which you'll save the IOS.
Download the IOS to the nonworking router

The best way to accomplish this is via Ethernet. Thealternative—using XMODEM through the console—will be very slow, even if youincrease the serial port baud rate to the maximum. So, instead, connect thePC's reverse Ethernet cable to the nonworking router (or use twonormal/straight-through Ethernet cables and a switch).

Without an IOS, the nonworking router will boot up in ROMmonmode. The prompt will look like this:

rommon>

Verify the necessary settings

On the console of the nonworking router while in ROMmonmode, use the set command to displaythe current settings, which the program will use to download the IOS via TFTP. (Fora Cisco example of these steps, check out this Ciscodocumentation.)

For example, here are the settings you must set for the tftpdnld command to work:

rommon> setIP_ADDRESS=10.253.100.126IP_SUBNET_MASK=255.255.0.0TFTP_SERVER=10.253.15.72DEFAULT_GATEWAY=10.253.1.1TFTP_FILE={the name of the IOS that is saved on the PC}

However, your settings may not contain any of the requiredvariables for the tftpdnld command.By default, it may look something like this:

rommon 9 > setPS1=rommon ! > BSI=0RET_2_RUTC=0RET_2_RTS=?=1

If this is the case, set the required variables. While itmight seem obvious to use the setcommand to set the variables, you can actually set the variables simply by enteringthe name of the variable, the equal sign [=], and the value.

For example, to set the IP address of the broken router, youwould use the following:

IP_ADDRESS=10.253.100.126

Final steps

After setting your values, run the tftpdnld command, which will replace the IOS. Listing A provides an example of how I restored a router.
An alternate approach to the tftpdnld command

However, if the tftpdnldcommand doesn't work for some reason, you can use the xmodem command to send the IOS over the serial console line. (Forinstructions for this process, checkout this Cisco documentation.) However, if you decide to take this route,it's a good idea to change the baud rate on the console and your PC to 115,200so it doesn't take more than four hours for an 8-MB IOS file to transfer overthe 9600-baud console.

On a final note, keep in mind that different models of Ciscorouters and different Cisco firmware versions respond differently. For example,these commands performed on a 2600 series router may not work on a 3600 seriesrouter. However, the basic process remains the same.
