I'm trying to modify the kernel of Windows 8 build 8250 (which is the Consumer preview). It throws a "Preparing automatic repair" error and restores the original files. Patching winload.exe to return STATUS_SUCCESS on 0xc0000028 doesn't work. Maybe I also need to do the same thing to bootmgr, but I haven't tried.

Does anyone has experience with Consumer Preview modification?

i had this same issue. got fed up and just ended up writing a bootkit.

it seems regardless of setting testsigning or nointegritychecks in the loader block that bootmgr still checks the digital signature of winload in windows 8.

just modify bootmgr or write a bootkit.
