How to get fdisk.exe?

Dear experts:

I think I need to run "fdisk /bmr" to reset MBR.  I cannot re-install Win XP.  I gt "inalid partition table" warning.

Hope you may kindly help me.

Thank you so much for your kind, prompt response.

I followed your tips and am going to resinstall OS.

I will update you on that.
Thanks agin!

Re-install the whole OS?
There may be an easier way, like Repair Install, or Check System files, virus/spyware checks etc...

Thank you again for your kind tips.

I can't do other things because the system could not boot up.
All I saw was "invalid partition table."

By the way, your first tip "fixmbr" did not work for some reason. So I am installing OS in the second partition (where I kept all valuable data), which was the last thing that I wanted to do.

Thanks again!

duta you should have waited my dear for  other EE to come in post suggestions.
If all is not lost here is mine.

Invalid partition table
Explanation: The system examined the master partition table to determine what volume to use to boot the operating system, and found invalid information within it.

Diagnosis: You should never see this message under normal circumstance. One way that this message can occur is if more than one partition is set "active" or bootable; only one is allowed to be at a time. It is possible that the master partition table has become corrupted.


The standard DOS and Windows disk utilities will not allow you to set more than one partition active. If you are using any funky utilities to manipulate the partitions, for example in a multiple-operating-system environment, run the utility from a floppy disk and make sure only one partition is set active.
There is a chance that the disk has become corrupted somehow. Troubleshoot this here.

additional information on FDISK /MBR?

Here's how

Dear Merete and Callrs:

Thank you so much for your kind help.

By the way, I tried all, but it is still not working.

The only practical solution seems to re-install OS by all means.

But I still can not. I continue to get "Caution: Installing multiple operating systems on a single partition is not
recommended. To learn more about installing multiple operating systems on a single computer, see"

The message keeps coming even though I reformatted the hard drive, select the partition to install OS and others.

I can not go past the point (To install windows on the selected partition, press Enter, to cancel press Esc) by all means. Every things keep coming back.

The following is the message that I keep getting:

You chose to install Windows on a partition that contains another operating system. Installing Windows on this partition might cause the other operating system to function improperly.

Caution Installing multiple operating systems on a single partition is not recommended. To learn more about installing multiple operating systems on a single computer, see (
using Internet Explorer. • To continue using this partition, press C.
• To select a different partition, press ESC.

Because I just reformatted the partition, there should be no operating system on the partition.

It is very strange.

Avatar of duta


I reformatted and tried to install OS nearly 10 times today.

I would like to figure out how to avoid the "Caution: ... ".
duta what operating system/s do you have on this one partition.
xp home or xp Pro
sp1 or sp2?
Is this an OEM xp.
What brand is your computer?
Is this a desktop or laptop?

Or have you installed linux?
Or have 2 windowsxp on one partition?
I need you clarify this as Linux has a partition.
2 xp will definately confuce your partition as I stated in my previous.

can you boot to safemode
tap f8 continously when the machine first posts.
choose safemode then log onto the administrative account.
once in there
r/click my computer properties advanced>startup and recovery>settings>edit>boot.ini

this my boot.ini for windowsxp pro running sp2. With one partition C drive.

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

go to start >run>type in msconfig >boot.ini
check boot paths Boot Options
make sure all is unchecked

How to Remove Linux and Install Windows XP;en-us;314458

12. Removing Linux and restoring your Windows partition to its Original state
 Removing Red Hat Linux
To uninstall Red Hat Linux from your system, you will need to remove the GRUB or LILO information from your master boot record (MBR).
If you need to remove Linux from a hard drive and have attempted to do this with the default DOS (Windows) fdisk, you will experience the Partitions exist but they do not exist problem. The best way to remove non-DOS partitions is with a tool that understands partitions other than DOS.

To begin, insert the Red Hat Linux CD and boot your system. Once you have booted off the CD, you will receive a boot prompt. At the boot prompt, type: linux rescue. This will start the rescue mode program.

You will be prompted for your keyboard and language requirements. Enter these values as you would during the installation of Red Hat Linux.

Next, a screen will appear telling you that the program will now attempt to find a Red Hat Linux install to rescue. Select Skip on this screen.

After selecting Skip, you will be given a command prompt where you can access the partitions you would like to remove.

First, type the command list-harddrives. This command will list all hard drives on your system that are recognizable by the installation program, as well as their size in megabytes.

  Be careful to remove only the necessary Red Hat Linux partitions. Removing other partitions could result in data loss or a corrupted system environment.
To remove partitions, use the partitioning utility parted. Start parted, where /dev/hda is the device on which to remove the partition:
parted /dev/hda
Using the print command, view the current partition table to determine the minor number of the partition to remove:
The print command will also display the partition's type (such as linux-swap, ext2, ext3, and so on). Knowing the type of the partition will help you in determining whether to remove the partition.

Remove the partition with the command rm. For example, to remove the partition with minor number 3:
rm 3    

  The changes start taking place as soon as you press [Enter], so review the command before committing to it.

After removing the partition, use the print command to confirm that it is removed from the partition table.

Once you have removed the Linux partitions and made all of the changes you need to make, type quit to quit parted.

After quitting parted, type exit at the boot prompt to exit rescue mode and reboot your system, instead of continuing with the installation. The system should reboot automatically. If it does not, you can reboot your computer using [Control]-[Alt]-[Delete].

Dear Merete:

I had Win Xp Pro. But now there is no OS in the system because the hard drive has been reformatted over and again.

There is no way to boot.

Still I get the same Caution again and again.

Thank you so much for your time and kindness.
