Some see this error preceeded by this code - 0C00252 - but I don't see this. I'm guessing this might one of Microsofts top secret error messages because references to it are few and far between. But obviously this a manual step I can't have in a task sequence.įirst thing I did was try to research this error. If I simply press Esc the task sequence continues and completes successfully. Press Esc to continue or F1 to enter Setup. Some essential variables are absent or corrupted and Boot Manager has restored them from default configuration. Then we changed to UEFI, for all the obvious benefits.īuilding a Windows 10 machine (using gpt disk) the first time is fine after UEFI is configured.īut when I try to rebuild it (using a separate rebuild task sequence which only wipes C:) I am now seeing an error after the first reboot after the Windows 10 Apply Operating System task has run.īoot Manager recover from critical error. The only thing I had to add in was a run command task step to reset the mbr, with Our rebuild task sequence flattened C: and then rebuilt C using content from D - all well and good. This worked perfectly when we built Windows 10 using legacy BIOS.

On the D: drive we store the cache folder for this tool, the idea being when we want to rebuild a machine we can do so from content on the local disk, and a bit of configuration in the task Our factory task sequence is built with a C: and D: drive. This tool basically caches task sequence and application/package content on the local disk, makes it available so peers who require software don't need to go We use a third-party content management tool which integrates with SCCM 2012 (we have have SP2). Getting a painful error when running a Windows 10 rebuild task sequence.
