Unmountable Boot Volume - cannot remove EPPC

Laptop with Endpoint Encryption shuts down unexpectedly.

After McAfee EEP logon screen I get a blue screen of the death “Unmountable_boot_volume”. Same issue if we choose “safe mode, last good know configuration…”

I’m “Authenticated from SBFS” and “Authorised” using BartPE with Safetech but when trying to lunch  remove EPPC nothing happens, I only can se “Safeboot removal process started, opening disk manager”  it seems hang…

Also if I lunch A43 or total commander nothing appears..

Any suggestion?

Re: Unmountable Boot Volume - cannot remove EPPC

You may try to remove encryption using SafeTech, or Force Crypt - decrypt sectors.

You have all neccessary information in screen above. Use exported machine information (to SDB file), but verify that first and last sector in a pertiton, can be decrypted with that SDB. For that, use workspace functions.

Re: Unmountable Boot Volume - cannot remove EPPC

Hello Peter_eepc,

I have never done a Force crypt-decrypt, can you please describe the process a little bit more or send me a link where I can found the needed information.

Thanks a lot.




Re: Unmountable Boot Volume - cannot remove EPPC

Export machine information (deselect users and file sets) to SDB file. Put SDB file on WinTech\SafeTech floppy or USB stick.

Boot PC with WinTech/SafeTech utility from floppy (or CD-ROM if you converted floppy image to bootable CD)


Authenticate from database - point to SDB file on floppy or USB stick.

Work with Workspace, load sector 63 from disk to workspace, decrypt workspace - see if there is clear text, if it is then proceed

Do the same for sector 312576704

If still good, go to Force Crypt menu, choose decrypt sector range and use 63,3125576642

Make sure that PC power is uninterrupted during decryption.

After is all done, replace MBR with Original MBR, or run fixmbr from Windows install disk.

Keep machine of the network and remove EEPC client (sbsetup  -uninstall).

Re: Unmountable Boot Volume - cannot remove EPPC

Done, but after 30 minutes decrypting I get this error message:

Endpoint Encryption Error

Error code 0xe0020007 – description: error reading disk sector.

Something more that I can try? Or everything is lost?
