517737 2007-01-20 03:37:00 Some help here would be appreciated :o

I'm working on an HP Pavillion (XP Home OEM) which had refused to boot. It came up with the unmountable boot volume on startup, so as per HP's site I tried to use CHKDSK to check the volume. Even trying to boot the "hidden" recovery partition caused the error, so I threw in my Win XP Pro to boot off, get into recovery console, and CHKDSK. My suspicions were alerted when the data partition didn't appear at all ...

I CHKDSK'd anyway, and rebooted ... no joy.

When that didn't work, after a bit more research I tried to do a FIXBOOT and FIXMBR. The problem now is that the NTFS partition (with all the data) was an "Unknown" type ... now it's a FAT!

:help:

How can I get the computer to recognise this "FAT" partition as an NTFS ... if only to recover the data? :badpc:

517738 2007-01-20 04:01:00 Have a look at this program (www.cgsecurity.org). it's helped me with a similar situation before except my lost partition was fat32.
There's a tutorial for recovering a Fat 32 drive here. (mirror.href.com). It'll give you an idea how it works

517739 2007-01-20 06:12:00 Thank you :lol: That was perfect ... at least it now is recognised as NTFS :) I have chkdsk running on it now ... thanks again davehartley (3487)
517740 2007-01-20 07:42:00 Update -- all go, boots again after chkdsk/fixboot/bootcfg. Thanks once again :D davehartley (3487)
517741 2007-01-20 07:52:00 No problems:thumbs: I'm glad it worked for you 4bes (2848)
517742 2007-01-21 02:12:00 The HP recovery partition is FAT 32--is that the partition you were talking about? RealBigDog (11623)
517743 2007-01-21 06:22:00 No -- I could see the FAT32 recovery partition, but the NTFS partition had been clobbered by something (brownout or power spike trashing the partition table?), and it was first "unknown", then FAT.

Using TestDisk, I managed to get the partition table back again, then a bit of work got the partition bootable again.

Better run Drive Image XML right away to get a backup while it's working.
