Hello,
before I try a Fixboot or Fixnbr to try and resolve a problem I have can
Someone tell me what each command does and if it works am I likely to get
back the same Windows Environment I had before my system stopped working?

Fraser,
You should expand on what this situation involves. What does "stopped working" mean?
Does the pc boot up? Can you log in to Windows?
Describe what happens and any messages (verbatim) that it shows.

You've already posted this same question in windowsxp.general and have gotten replies.

Thanks Maurice.
Although I posted already, and received replies, I did not get an answer to
the basic question of what Fixboot or Fixnbr will do to my windows set-up.

Will I lose all my folders/data etc. on the HDD ??

The problem I have is that the machine goes through its bios boot then tries
to start up windows .

I get the "NTLDR is missing" message.

I've gone through the trouble shooting process (using the repair disk) I can
see the NTLDR file so this leads me to the conclusion that there is
something wrong with the boot sectors of the HDD, but I'm guessing.

Fixboot or fixnbr appear to be commands I can use here BUT I'm wary on using
them unless I know what the consequences may be. - hence my post.

Thanks for posting some links, I'll have a look at the and hope they tell me
what the "Fix" commands actually do and if I will lose data.

You will not lose folders or data by using Fixboot or Fixmbr.
Fixboot writes a boot sector to the system partition. The fixboot command is only available in the Recovery Console.

Fixmbr repairs the master boot record of the boot disk. The fixmbr command is only available in the Recovery Console.

On "NTLDR is missing" : Sometimes it 'may' be caused to having resized the boot partition.
Do you recall having done that?

Re-extract the file "NTLDR" from XP CD.
Set pc boot sequence (in BIOS) to boot from CD first--- Boot from XP CD --- then get into Recovery Console---then do

copy X:\i386\NTLDR C:\
----where X should be the drive for your CD , and presumes C is your XP system-drive on disk-drive.

btw, NTLDR is a hidden & system file, and should be in the root (system-drive) folder ....e.g. C:\

http://support.microsoft.com/KB/314079

If you have access to a working XP pc, you may 'carefully' make the diskette from there. I mention carefully, because if there is a mix of SCSI & ATA hard drives or a mix of single O.S. & multi-boot O.S.'s between the 2 pcs, then it gets quite complicated & editing will have to be done!

Fixboot writes a new partition boot sector to the system partition. The
fixboot command is only available when you are using the Recovery Console.

The following example writes a new partition boot sector to the system
partition in drive D:

fixboot d:

You must remember that:-
Using the fixboot command without any parameters will write a new
partition boot sector to the system partition you are logged on to.

Where as Fixmbr repairs the master boot record of the boot disk. The
fixmbr command is only available when you are using the Recovery Console.

The device (drive) on which you want to write a new master boot record.
The name can be obtained from the output of the map command. An example
of a device name is:

\Device\HardDisk0.

Example

The following example writes a new master boot record to the device
specified:

fixmbr \Device\HardDisk0


If you do not specify a device_name, a new master boot record will be
written to the boot device, which is the drive on which your primary
system is loaded.
If an invalid or nonstandard partition table signature is detected, you
will be prompted whether you want to continue. If you are not having
problems accessing your drives, you should not continue. Writing a new
master boot record to your system partition could damage your partition
tables and cause your partitions to become inaccessible.

OK tried this managed to find the NTLDR and NTdetect files on my working
machine - BUT can't find the boot.ini file - no matter what search I carry
out ( having unhidden system files etc. !!)

Under "Repair" on the non-working machine I can see the boot.ini file but
cannot copy it to the floppy disk I created - I keep getting the message
"Access denied" - even if I change the attributes..

Any other ideas how I can fidn the boot.ini file on my working PC?

When embedding replies in existing text, please mark your
own lines clearly so that respondents don't have to guess what's
yours and what's someone elses.

If you cannot find c:\boot.ini, make your own file, using any
text editor. It should look like so:

[Boot Loader]
Timeout=3
Default=multi(0)disk(0)rdisk(0)partition(x)\WINDOWS
[Operating Systems]
multi(0)disk(0)rdisk(0)partition(x)\WINDOWS="Microsoft Windows XP
Professional" /fastdetect

The usual value for "x" is 1.

However, making a new boot.ini file won't help if you get the
"ntldr missing" message. You really need to run fixboot, and
perhaps fixmbr.

Always have current backup of important data. If the system won't boot
put the drive in another computer as a slave drive and backup the
essential data from there. Then try the fixes.

The BOOT.INI is a hidden and read-only file found in the root of C drive.
If you can see it on another machine, assuming you are in Notepad, you can try "saving a copy" using "Save AS".
