Problem booting

[team4344]

Hi

I have a laptop HP Omnibook 500, it intermittently used to boot and say "Operating system not found". However if i tried to reboot it would not happen and windows would boot fine. Also i used to get many BSOD one to do with classpnp.sys and another when i plugged in a logitech mouse... but this only occured recently.

Now this message appears all the time and i cannot boot into windows. I am also getting a new message, when i boot up, it says

Save to disk partition not found
Save to disk feature disabled
Run PHDISK for information
FILE : Create new
PARTITION : Consult Manual
Press Any Key to Cont...

Does anyone know what this information means ?

Can i use the Win XP CD to run a repair and if i do will i loose any files ?

Any help and information would greatly be appreciated.

Hi,

PHDISK sounds like a program that HP would supply with the laptop to set up a suspend to disk (or save to disk) partition.
A suspend to disk partition is often used on laptops to allow the exact state to be saved to disk, and restored within seconds. It needs to be big enough to store all physical and virtual memory plus video ram etc.

I don't think the Windows XP CD will be able to fix this, but if you don't have it on a HP utilities CD-ROM or can't find it with a quick google search I would go in for warranty repair.

There are issues with your hard disk drive.

PHDISK is a laptop utility used to create a hibernation partition. This is by the manufacturer and not a Windows service feature. See, for example:

Use the XP CD to run the Recovery Console. The command you need to run in Recovery Console is chkdsk /r

Repairing XP is unlikely to address the underlying problem you are having with the computer. Either the pre-allocated PHDISK partition has become corrupted, or there is a physical problem with the hard disk drive, or both.

Chkdsk should repair the logical structure of the drive and clear any issues, if possible. What sounds more likely is that the PHDISK should have been disabled in BIOS prior to the upgrade to XP. See:

It is likely a BIOS upgrade is needed for the notebook as well.

This is an older hibernation partition and not needed with XP.
