Getting below Error while booting to 19H1 windows UEFI OS: "BL InitializeLibrary failed 0XC0000185" How can the same traced from efi boot loader bootx64.efi? how can we capture logs of bootx64.efi?
First this is a common issue (the BL
stands for bootloader), see https://www.lifewire.com/fix-error-code-0xc0000185-4691254
Possible paths to debug UEFI are listed in https://ami.com/ami_downloads/Intel_Technology_Journal_Debugging_Firmware_Based_on_the_UEFI.pdf
You could try if your machine has a USB debug port (https://www.coreboot.org/EHCI_Debug_Port) or enable UEFI strings or, what is best, search for the JTAG port of your motherboard (https://it.toolbox.com/blogs/emiribric/jtag-interface-as-a-tool-for-repairing-various-types-of-motherboards-part-2-062619)
