The gist is that a UEFI system has Windows UEFI installed, and it works. Upon PXE booting Fedora, it breaks the Windows install somehow. Because removing the 440 bytes of MBR code, and all of the Fedora partitions doesn't unbreak this, I thought something must be up in NVRAM. But there's no change to NVRAM between the working system and the unworking system. The original poster determines that the disk can be "wiped" and Windows reinstalled, and is then bootable again. However the fdisk -l results for post Windows install indicates a single PMBR entry (expected), but then after Fedora is BIOS installed, fdisk -l reports only the GPT entry which is really not expected. So I don't know what's going on, but there may be an obscure parted bug that induces the triggering of unrelated bugs in fdisk and this computer's UEFI firmware (or maybe the hang isn't the firmware, but could be the Windows EFI bootloader). Anyone else with more MBR and GPT experience want to check the before and after partition maps, they're attached to the bug report?
