I'm experimenting with UEFI platforms currently in a VMware Workstation 9.01 environment with the'firmware = "efi"' entry added to the .vmx file. I haven't tested on physical hardware yet.
In UEFI mode, if the *boot media* does not match the *boot image* associated with the task sequence, boot image (WinPE) staging to the virtual GPT disk fails; however, the staging process has always worked with BIOS and MBR configurations.
Based on what I see in the logs and via diskpart.exe in the WinPE, the disk is:
- Converted to GPT
- Partitioned
- Formatted
- Assigned a drive letter
OsdDiskpart.exe is used to initiate this process; however, the 60GB .vmdk has no free space afterward. And even after I manually partition and format the .vmdk with plenty of free space available, WinPE staging still fails.
Is this an issue anyone else has experienced? I believe this to be a ConfigMgr 2012 SP1 bug that needs fixing.
What does OsdDiskpart.exe do exactly? What's handling the WinPE staging process?
