Bootloader are getting lost sometimes

STHN

Hello,

I have a customer which has about 380 machines with Windows 8.1 and SGN 6.10.

About once a month on one of the machines the Sophos boot loader appears to be missing and has to be recovered.

In that time no challenge response recovery is possible.

I think this can happen from time to time but once a month is too often.

So I was wondering what could cause damage to the boot loader? Is there any specific user behaviour or hardware configuration that increases the likelyhood of bootloader issues?

Thanks in advance!

    Hi,

    the Sophos Bootloader that is required for the BitLocker Challenge/Response, can under certain circumstances be removed (or changed in its order) by Microsoft. Updating a Windows 8 client to Windows 8.1 is a common example.

    As of SGN 7.0 there is as service, that checks the availability of the required NVRam entry and repairs it if required.

    Hope that helps.
