I'm seeing the same thing and have ticket #246201
open with support. Same conditions, I think. Let us know if there's anything different for you.
Rescue Media Builder for WRBM (boot menu) for the versions that failed with 8.1.7638 previously worked with 8.1.7544, and all show Windows 10 RE version 2004 (64-bit
) while the OS is Windows 10 Pro 22H2 build 19045.3324,
I suspected that Windows Update might have done something to the Recovery Partition for the recent spate of very complicated Security fixes, so I repeated the testing with Secure Boot turned off, but the results were the same ... error code 0xc000A004
and complaints that \Windows\System 32\ntoskernel.exe
was missing or had errors. It's not missing in the Wim in the staging area on the PC, which is where WRBM boots form.
Rebuilding RM with Win PE 10 worked for me, as did resurrecting the ISO file from the previous version of RM with Win RE 10 built under 8.1.7455 and booting it via flash drive.
The system that failed is the second one here to get 8.1.7638; the first was my guinea pig laptop running Reflect v8.1.7638+ on Windows 11
Home 22H2 22621.2215+ , and it works. It uses WinRE 11 build 22621
from the Recovery partition.
