Hi everyone,
I upgraded my dev box to 8.0 HF2 yesterday after reading from the release notes that I could use WinPE 10. After the upgrade completed I removed the Windows 8.1 ADK, installed the Windows 10 (update 1511) ADK, imported it, and then upgraded my WinPE 5.1 to 10. I then recreated the preboot configurations (PXE). Everything shows that I'm on WinPE 10. My problem is that now I can only boot machines with legacy BIOS enabled. When I boot with UEFI enabled, I get a PXE-E99 error. With WinPE 5.1, I had no problem booting with UEFI BIOS enabled. So I'm wondering if I missed something or if anyone has seen this type of issue before.
I've recreated the preboot environment several times with no change. Any suggestions are welcome.
