HP laptop - safe boot corrupted error 92h

This is a W7 HP Laptop Probook 4520S.    Yesterday, a free version of Advanced System Care was installed and run.  There were no problems with the system after the "clean up" by the Advanced System Care product.  The system was shut down normally last night.  This morning, on start up, the laptop goes to the password screen, is then keyed but instead of the Windows screen, we get "starting drive encryption" followed quickly by  "Safe Boot has been corrupted, 92H".  I may not have all of the words exact but close.  The system's drive was never intentionally encrypted.  We're trying to boot via a CD and cannot seem to do that either.  I think I may have an image on the drive which we could possibly use.

Restore your system to "the-day-before-yesterday" (and if possible avoid "advanced" optimization, registry-cleanup, and general cleanup programs;  Simple tool(s) such as "Ccleaner" are more than sufficient for the average user.  This is only an opinion).

That is exactly what I want to do (restore prior to install of program) but cannot find a way to get to the operating system so that we can get to a restore function.  Anyone have ideas on how to get there?  The HP Recovery Manager appears to only allow for a full restore of the factory image which will format the entire hard drive.  I don't want to do that since I have a OS partition and a Data partition on this system.

Power on; after the HP Bios screen, hold and keep F11 pressed (try pressing immediately after power on also).  You should see a windows that'd have a system restore option.

Holding down the F11 key immediately after powering up gives us the password window.  Upon entering password, we get "windows loading files" and then window with System 32 etc.  and please wait followed by HP Recovery Manager Wizard.  Unfortunately, there is no option but NEXT.  The only option with NEXT is a restore to factory state.  No option to do a system restore.

Could you get to a command prompt (many ways)?

If you can.  Type: "rstrui.exe" (c:\windows\system32) and hit enter.

I do not know how to get to a command prompt when I cannot get to the OS or any portion of it.  The only way I can think of doing this is via something like BARTS PE.  Any other ideas for getting to a command prompt?

In this case: Bootable BartPE or Windows install CD/DVD or a linux bootup CD.

Well ... this can be tricky.

Since you can boot to the recovery partition with no problem to do a full factory restore, I'd take the easy way out and do the following:

(1)  Copy the entire data partition to an external hard drive.    You could do this a couple of different ways ...

    (a)  Boot to a Linux live CD and use it to do the copy
    (b)  Boot to an imaging program (e.g. Image for DOS) and simply image the data partition to an external drive.    You could later restore this image; or use an "image viewer" to simply extract the data you need from it.
    (c)  Remove the drive;  attach it to another computer using a USB bridge device; and copy the data from the partition -- then replace the drive.

Personally, I'd probably just do (c) ... but (a) and (b) don't require removing the drive.

(2)  Now -- with the data from your 2nd partition safely "tucked away" -- just boot to the HP recovery partition and do a factory restore.


If you'd prefer to continue attacking the 92H error, we need to confirm the source of the error.    From a quick Google search, this error seems to be associated with McAfee's Endpoint Encryption (formerly known as SafeBoot).    Does this PC have McAfee installed on it?    You said you never intentionally encrypted the drive, so my best guess is that if McAfee is installed, you've encountered a significant incompatibility between that and the 3rd party utility (Advanced System Care) that you installed.     [FWIW, I echo the comment above about avoiding these kind of "swiss knife" utilities !!]

You noted that you "...  may have an image on the drive which we could possibly use."
Created with what program?    If it's from a bootable 3rd party CD (something like Acronis, Image for DOS, etc.), then by all means boot to that 3rd party tool (e.g. IFD), and see if that program can "see" the image.    If so, you should be able to simply restore the C: drive from that image and all should be well.    UNLESS the McAfee Safe Boot has modified the MBR -- in which case the restore won't work.    If you CAN boot to the 3rd party imager okay, you may want to first image the data partition to an external drive, just to be sure (as with the option I discussed first) that it's "safely tucked away".  [I'd also copy the image file to another disk, just in case ...)    THEN try restoring your image file and see if that resolves everything.    If so, you're done.     If not, you can then do a full disk wipe [write zeroes with WD's Data Lifeguard or use DBAN); and then restore the system image followed by the data partition image.

If the corruption happens to simply be the MBR (perhaps modified in some way by McAfee to add the SafeBoot code), you MAY be able to resolve it by booting to a Windows 7 DVD, choosing Repair - Command Prompt; and typing "BootRec.exe /fixmbr"     But before modifying the MBR, I'd be sure to see if you can image the data partition and confirm whether or not you have an image to recover from.    While this MAY be a simple fix, it could also wipe out your ability to boot to the HP restore partition.

Unfortunately, we attempted to install a new drive (as a test of the system) and in so doing, broke the KB cable which has rendered this system basically useless.  We could not get Bart's PE or the Linux bootable CD to load.  Regarding the new drive install, unfortunately, HP's design with this particular laptop model,  has the hard drive under the KB and to remove it requires a great deal of care to release the cable from the motherboard.  Thanks to all that tried to help and in particular with the extended instructions from "garycase".
