View Full Version : Fix the MBR in Windows XP

January 20th, 2003, 06:34 AM
Boot from the windows XP CD, press the "R" key in the setup in order to start the restoration console. Select your windows XP installation from the list, and enter the administrator password.
Enter the command: "FIXMBR" (without the quotes) at the input prompt and confirm the next question with a "Y" (without the quotes). Use exit to restore the computer.

I had to use this on a PC that I had corrupted the MBR with by using a boot manager.

Worked perfectly. This may have been posted before, and if so, forgive me. If not, now you know how to repair your MBR. By the way MBR stands for Master Boot Record. THis procedure kind of replaced Fdisk I think.

Awesome fix. I had a half baked install of bootmagic on an xp machine. Fix MBR worked great (although after reading the warning in FIXMBR about ruining partitions etc., I held my breath until I had successfully rebooted into XP). Thanks for the fix.

a word of caution.. sometimes there is no adminsitrator password entered (by you) but the program insists on a password.

microsoft admits there is a bug in its XP and there is a workaround for it. i know because it happened to me. it was no fun not realizing it was a bug until way after the fact and cure.

There's the knowledge base article from Microsoft that shows how to fix what cityman posted. Thanks cityman for your contribution. Luckily I didn't run into this issue, but now if users do, there is a fix.

Well thanks for the tips, but on my HD both the FIXMBR and FIXBOOT commands did not do the trick. In the end, this is how I solved the problem:

I added an old 1GB hd to the primairy IDE controller, connected the drive I wanted to repair (a 40GB Maxtor HD) to the seconday IDE controller, installed windowsXP on the 1st drive (the 1GB drive). The broken disk was a Maxtor HD. I downloaded maxblast 3 for windows (not the floppy version or ISO version, which both should work also) and run maxblast 3 from the freshly installed XP. I corrected everything on the Maxtor 40GB drive (setting it as boot drive and making a new 15GB partition with NTFS).
Maxblast copied everything from the 1GB XP OS and builds up a new OS on the new partition. Shutdown the PC, removed the old 1GB HD and started the PC again...DONE

KUDOS to Maxtor!

(remember for using this trick you need a Maxtor HD)

For what it's worth... I have always just
booted off of a windows 98 boot disk and typed "fdisk /mbr" without
the quotes of course and voila, she b fixed... :)

Please advise me if this proceedure is a dangerous method, so far it has
worked for me...


thanks...

Yes, works fine with XP... :)

I got this info along time ago when i was playing around
with Lindows (Linspire) and couldn't get rid of the dual boot
screen, Lol

It also worked with "Xandros" for me too, but i wanted to be
sure not to mess up or cause any probs for anyone here..!

Thanks..!

Be VERY careful with FDISK /MBR. It rewrites the master boot record. If the machine is multi-booting XP and another OS, /MBR may blast away the boot loader, thus crippling multi-boot capability. It may also wreck multi-boot capabilities under Win 9x if programs've installed a boot manager that /MBR overwrites.

Thanks for the word of caution. Always pays to be cautious and before doing anything ask or research it.

It's odd that this procedure doesn't work. Everytime I have had an MBR issue the fix I posted above worked.


You could try a few things...


Run a repair install
Reinstall over the existing installation

Or using the XP disk, make a new partition, and install XP that way. Then you'll be all set.

First of all, I have a Western Digital WD1000BB - 100 Gb 7200 RPM EIDE HDD. It is a secondary drive (no Executable files at all, just text, Pics, and music). It HAS been running fine for about 3 years until 11/18/2005. When booting the computer, I got a "S.M.A.R.T. imminent drive failure error" and said that the drive was bad and needed to be replaced. I thought it was referring to my PRIMARY drive so I disconnected the WD21000BB wrote Zero's to the Primary drive and then reloaded the OS. When booting up again after Re-connecting the WD1000BB, got the SAME error again. I powered OFF the computer and INPLUGGED the WD1000BB and rebooted the computer. The error did not re-appear. I powered off the computer and reconnected the WD1000 and booted up the computer again, and the error appeared. I allowed it to continue booting up. It booted up. The WD1000 was detected, BUT was showing "This drive is NOT FORMATED.I removed the drive and attached a DIFFERENT WD HDD. It booted up fine and showed ALL of the data on that HDD. Is there ANY THING I can do to RESTORE or Reconstruct the (MBR) for the partition and recover the data? This was NOT a bootable drive (no OS on it, just non-Executible files). I have not done ANYTHING to the drive since it failed. I have some irreplacable files on it. HELP!

I'd take the hard disk and put it in a working system. THen I'd copy the contents.

You shouldn't need to fix the MBR to read the contents on the drive. The MBR just allows that drive to boot.

If it is not a bootable drive, there is no need to fix the MBR. YOu just need to hook the drive up and copy the contents as quickly as possible. It sounds like the drive is dying.

Worf,
BB's got the only solution I can see. Drag the 100gb into a working system as a slave and see if you can get any of the files out. Western Digital has pretty good Disk Utilities. You might be able to copy the disk onto the master, depending on how much free space the master has and how much data is actually on the 100gig. If you try this, it generates alot of heat. Keep the case open and an external fan on it. I think this your best shot. If the drive wont drive or the reader wont read, you're pretty much screwed. Last resort is to take it to a shop that specializes in data recovery. There are hundreds of them.

Have you at any time during this ordeal formatted that drive? If so, your data is erased and you'll have to use a recovery software to get the data back.

My problem same as Worf. I've tried the following:-
1) Boot using XP disk, run the console recovery and run the fixmbr ... failed.
2) Tried to copy out the files (excel, word and pic files)...failed

FYI, my second hd is detected by BIOS but not in My Computer. If I boot up the PC with the problem hd attached as 2nd hd, the error message "Third Slave Disk Error" will displayed. Then I need to press F4 to by pass it and the Windows XP will launch from my 1st hd.

PLEASE... Anyone can help me to recover all my pictures (contains all my wife and kids pictures since beginning) and files.

Thanks in advance.

Do you have a disk enclosure? For example an external hard disk enclosure?

If so, put the problematic hard disk into the enclosure, then boot the pc with a good hard disk with XP loaded.

Plug in the enclosure and see if your computer can read it. If so, copy all the files you want onto another media (DVD, empty hard disk, CDRs...)

THen format the drive and start over.

If you don't have a hard disk enclosure, try booting with the XP cd, instead of running the console recovery, try doing a repair installation on the hard disk.

http://www.michaelstevenstech.com/XPrepairinstall.htm

You can view how to do that at the site linked above.

If none of that works, post back in this thread and i will try to think of something else.

One question about the third slave device error, do you have the 2nd hard disk as a slave or master when you booted it?

Would it not be possible to simply
* Insert Windows XP CD
* enter recovery console
* copy command.com and fixmbr.(com, exe) to corrupted HDD
* Go to drive in question
* Type command.com (will effectively create a command session generating the appearance of system drive?)
* Type FixMBR


As I read in a Windows XP support page, FIXMBR only operates on the system drive! So if you boot from the CD, it'll try to re-write the MBR on the CD.

This should work, assuming the Windows XP kernel respects the command interpereter. Each time you run command it creates a new session inside the first one, most of the environment variables should be moved over to the HDD.

This would likely work, but how many people even know how to use the command line to copy files today? Or even to switch directories for that matter?

But this will not work if the hard drive is dead..

I was trying to make the process as simple as possible for someone who is uncomfortable with command line procedures.

FIXMBR is about as simple as it gets...

As I read in a Windows XP support page, FIXMBR only operates on the system drive! So if you boot from the CD, it'll try to re-write the MBR on the CD.

The system drive was the drive you are trying to fix the MBR on... not the CD... I don't know what you are talking about when you say "So if you boot from the CD, it'll try to re-write the MBR on the CD."

You use the CD to boot to the recovery console. That puts you at a command prompt. YOu type FIXMBR and it repairs the master boot record of the system drive. The system drive being the drive that holds your windows XP installation...

HELP!

After reading this thread (found it doing a Google!) I think you might be able to help... I have a very similar problem.. (this might be long winded.. but I really need to get this drive back as it has photos of my son on it and I never back it up... :( )

The drive in Question is set up as my Primary Slave and was just a spare drive to store work, Gen' stuff on and the odd program

I noticed one day that some icons on my desktop had the default Windows logo, and not there actually ones. I went to check the programs that I had installed on to this drive (happens to be D:\) and when I double clicked to open it, it said that the drive wasn't formatted and did I want to format it now... HELL NO I said...

Well, I booted up the PC with a Partition Magic 8 Bootable CD and it said that Drive 1 and 3 were fine (they showed the right size and usage) but drive 2 (the problem drive) wasn't active. I set it to active. but still not joy in windows. I checked in Disk Management and it shows all 3 HDD, but D:\ doesn't have a File system like the other two. (both NTFS like D:\ used to be.)

So.. .if anyone can help... I'd owe them many a Beer... (not sure how I'd get the beer to them... but I'd try my damn'est!...

First I'd check the cables, power etc.... unplug then plug it back it. Boot and see if you can read the drive.

If not, check here:

http://www.pcguide.com/ts/x/comp/hdd/fileBadCorruption-c.html

I'd be careful. If you value the data, then you might just want to use some other tooks to retrieve the data.

Another option would be to use a Linux Live CD and see if you can access it from there. The live CD should make no changes to the disk, and might be able to access it.. but I dunno for sure.

I need some info on fdisk /mbr. Do you type it on the win98>. I am not getting any fix or any response when I type it in, it just goes back to the prompt. I am running XP Home, upgrade version from 98SE. My cd does not boot, it is an upgrade. My 98SE cd will boot. Thanks, be as detailed as you can please.

I am running XP Home. Two days ago it would take forever to boot. It will take over a minute on the black Windows screen, then take another two minuts on a blank screen before it takes you to user password screen, then everything works kind of normal. It does not do this in safe mode. I tried last known config, restoring to an earlier time when this didnot happen but nothing changes same problem. I tried all my anti virus, spyware, malware software and it looks clean. Hijackthis looks clean. I cannot get it to boot from a cd because the boot won't give me that option on boot up. It is configured to boot from cd first but it won't. Help please. The whole boot process takes betwwen 5 and 6 minutes to get to the welcome screen. Correction, it will let me boot to cd but this cd is an upgrade to XP from 98. It will recognize the 98 cd but not the XP upgrade. I was trying to fix MBR to see if that will work. Any ideas.

You either have a virus, spyware, adware, or something else like that. If your computer will boot (even slowly), your MBR is fine AFAIK.

Check that thread out on the double time! Move it soldier. Be all that you can be, get an edge on life in the spyware thread!

Also something else that might slow up your booting times:

Do you have a boot time defragger installed? Have you isntalled any software recently? Have you tried messing in the MSCONFIG settings under the startup tab * go there and remove any unnecessary crap*.

Honestly you should do a clean install, instead of an upgrade from windows 98.

So I've been reading this thread with interest. My situation is this:

Installed GoBack 4 on an XP Home Toshiba Laptop that didn't like it. System posts, gives the Windows logo and then fades to black. Can boot into Safe Mode. The Symantec site shows that this can be a problem and blames a corrupted MBR:

http://service1.symantec.com/SUPPORT/goback.nsf/docid/2001101713193807?

They provide an ISO to create a bootable disk that has utilities to correct the issue, but they didn't work. I check with Toshiba to see if the MBR is locked in some way and they say no. The solution they offered me was a complete system restore back to factory. Not so keen on that.

Next I decided to go about repairing the MBR the ways suggested by this thread. Problem is that I can't load the Recovery Console because of the password issue with my admin account. I read up on the fix offered by MS, but the system I am using \doesn't have a floppy drive. Is there a way to access the appropriate utilities otherwise? I have a 98 SE upgrade disk, but it won't let me boot to it. Strange because I am able to boot to the XP cd...

Any suggestions??

Thanks. I had been avoiding the option to restore the system to the last known config that had worked when booting. I was afraid that it would somehow screw up my ability to uninstall GoBack. It turns out that restore to a previous config indeed got things going again, and I was able to uninstall GoBack using Add/Remove.

Hey... new to the forum... I'm having some problems installing winxp & was hoping you guys may be able to offer some advice. I used to have my machine set up as a dual boot (win2k & fedora core 4) with grub being the bootloader. It was giving me a ton of problems so I eliminated linux & reinstalled win2k. Now I'd like get winxp pro running on my machine... so go through setup & the machine reboots... when it restarts after the initial setup, it just quits. It tells me "press a key to boot from cd rom". If I just let it go, grub eventually comes up but does nothing. I've tried booting into recovery mode & using fixmbr with no success. Any suggestions? Thanks.

I don't know why you have grub as a bootloader if you only have XP and 2000 on the computer.

To Remove Grub From Your MBR. just use the command fdisk /mbr...
boot your computer with win 98 or ME and start computer with cd rom Support. at the command prompt enter the command fdisk /mbr and then reboot your computer... your Grub is removed...

Try that.

If you ran the XP setup from the disk and CHOSE to format the entire disk, it should have overwritten the bootloader. That is if you formatted all the partitions on the drive.

Make sure you have formatted them all, and then try the Xp installation again,

Using the procedure below:

Yes, I know all this & that's what I did, thinking that would fix it. Still no luck. Maybe part of the problem is this...

I admittedly have a pretty limited understanding of how bootloaders work, so bare with me here. I have 2 seperate hard drives. One is booting win2k, the other is storage. My intention was to install xp on the hd I was using for storage. That way I could still boot up my pc in the event that xp didn't install correctly. My guess is that when the boot screen comes up, it's looking for the boot sector on the "storage" hard drive & there is none (does that make sense?) I am reformatting the drive & making sure any previous partitions are erased. I tried the fixmbr thing in xp recovery mode & nothing seemed to happen.

The fixmbr will only work if XP is installed on the drive. If it is not installed, then it won't work I believe.

I would totally start over, with a clean install of windows 2K, wiping the entire hard disk (that should get rid of the grub loader), and then install XP on the second hard disk. That should then make XP's boot loader the default and 2K an option on the Xp boot loader menu.

The disk ( a WD raptor sata 74 gb) fail to boot after a strange system lock.
Using thunderbird and opening a note, the screen went almost blank and system froze. After that no boot capability any more.

Inserted the failing disk as secondary drive on another system.
This system has its own primary sata drive, working all rigt with WIN XP.
Went to my computer  manage  disk management, and it said that Drive 1 is fine (they showed the right size and usage) but drive 2 (the problem drive) wasn't active. I set it to active. And the message is that the disk is unformatted and unallocated.

For all I read on this fantastic forum plus others p[laces, the MBR record could be damaged.

The disk was formatted as 4 partitions NTFS (20 + 20 + 20 + rest of disk), being the first partition the active boot unit.
Is there a simple way to read the information actually on the MBR record and see were the problem could be.?? Or any better suggestion>???

Thanks in advance

Juan

I believe there is a way to actually "read" the MBR but it's done using a Live Linux cd...I'll have to look around, but I'm thinking that it's on Knoppix or maybe Whoppix.

Anyone else know?

Anyways, it isn't an easy task by any means. The FIXMBR should fix the problem and let you back to your data unless the drive has just died altogether.

Boot from the windows XP CD, press the "R" key in the setup in order to start the restoration console. Select your windows XP installation from the list, and enter the administrator password.
Enter the command: "FIXMBR" (without the quotes) at the input prompt and confirm the next question with a "Y" (without the quotes). Use exit to restore the computer.

I had to use this on a PC that I had corrupted the MBR with by using a boot manager.

Worked perfectly. This may have been posted before, and if so, forgive me. If not, now you know how to repair your MBR. By the way MBR stands for Master Boot Record. THis procedure kind of replaced Fdisk I think.

Hey George,
From the Philippines eh? Our Admin. Conan is also from the Philippines. You should send him a shout or two. I'm sure he'll be glad to hear from a fellow countryman.

As for the SP2 download:
http://www.microsoft.com/downloads/details.aspx?FamilyId=049C9DBE-3B8E-4F30-8245-9E368D3CDB5A&displaylang=en

Try the Microsoft site. That should give you the installer for SP2 that you can use to install on a computer or over a network.
