Hello all,

1) I have a problem with my HP laptop, running Windows XP Home Edition.

It was not booting into Windows and was ending with Blue screen Error
Message:
"UNMOUNTABLE_BOOT_VOLUME".

2) Microsoft Knowledge Base kbid=297185 said to boot into Recovery Console
using boot floppy or cd and to run CHKDSK /R to try & repair.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3) -I managed to run CHKDSK /R 1st time from boot floppies.
Recovery reached 25% before it stopped.

-I managed to run CHKDSK /R a 2nd time, this time it reached 75% completed,
then went back down to 50%, then eventually back up to 63% before it stopped
with following Error:

"The volume appears to contain one or more unrecoverable problems".

-I have run CHKDSK /R 3rd time from Windows XP CD. It does not repair any
further and I get same Error as above:

"The volume appears to contain one or more unrecoverable problems".

If I try DIR, I get Error:

"An error occurred during directory enumeration"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4) In Recovery Console, DISKPART command shows:

28616MB Disk 0 at Id 0 on bus 0 on atapi [MBR]

--: Partition1 [FAT] 24MB (9MB free)

C: Partition2 [Unknown] 28592 MB (28592 free)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5) Looking at Recovery Console commands, I also see there is a FIXMBR and
FIXBOOT command.

FIXMBR shows:

"This computer appears to have a non standard or invalid master boot record.
FIXMBR may damage your partition tables if you proceed, This could cause all
the partitions on current hard disk to become inaccessible. If you are not
having problems accessing yor drive, do not continue."

-Could FIXMBR, FIXBOOT commands be of any help now or later ??

=================================================
-What else can I do to to recover my files/data ??

-Could FIXMBR, FIXBOOT commands be of any help now or later ??

-Would installing 2nd instance of Windows XP maintain old file system
allowing me to recover files/data ??

-Are there any other tools I can use to recover/access the data ??
=================================================
Many thanks

Another method is to boot from the win xp cd and do not
select repair. Select new installation. In a few steps it will
detect your previous win xp installation if it is still there.
Then it will offer to repair that installation. Now DO choose
Repair. It will reinstall any files that may be corrupted and
write the mbr again.

Doing the Repair I mentioned first may fix this.
But then
sometimes this will happen if your memory is going bad.
Download memtest and do a thorough test of memory.
Next, run a hard drive diagnostic.

Where do you download Memtest from ??

www.memtest86.com

You want either the .iso to make a bootable cd or the precompiled
Windows binary to make a bootable floppy. Boot with Memtest86 and it
will run immediately. Normally you don't need to change the default
configuration. Allow the test to run for a while, unless you get errors
immediately. If you get errors, replace the RAM.
