I am having an issue with deploying Windows 7 x64 to certain Dell models with
UEFI enabled. So far the models I have seen it on are Latitude Exx30 and
Latitude Exx40.
I have them set to boot in UEFI mode with Legacy ROM options disabled during
the initial UEFI network boot. After it applies the image and reboots, I
started getting the Windows Boot Manager error:
File: \EFI\Microsoft\Boot\BCD
Status: 0xc000000d
Info: An error occurred while attempting to read the boot configuration data.
Found forum post indicating Legacy ROM options needed to be enabled for Windows
7 even if booting into UEFI, so I added a command line to re-enable that during
the task sequence and that resolved the issue on some of the models (including
but not limited to the OptiPlex 5040). On the Latitude models I mentioned
though, it will not boot into Windows after that. I can hit F12 to get into
the Boot Selection screen and select Windows Boot Manager option under the UEFI
list, but it doesn't recognize that as a valid boot option and moves on to the
next, which is always the legacy mode network boot.
I even tried reversing course on these models for Windows 7 x64 and going back
to Legacy Mode, but after switching everything back in the BIOS...after it PXE
boots the task sequence isn't able to write to the hard drive for some reason.
I get this error message after each step:
Failed to save the current environment block. This is usually caused by a
problem with the program. Please check the Microsoft Knowledge Base to
determine if this is a known issue or contact Microsoft Support Services for
further assistance.
The parameter is incorrect. (Error: 80070057; Source: Windows)
I also have a reboot back into WinPE step early in the task sequence, but it
fails to stage the boot image and the task sequence errors out. I brought up a
command prompt and I'm able to see the drive with Diskpart and the format and
partition step of the task sequence completes successfully.
I am at a loss on these, at this point I don't really care whether I go with
Legacy or UEFI, I just need one of them to work. Any suggestions/theories are
welcome.
Thanks in advance
