Cannot boot WinPE, can boot Macrium Reflect USB. ASRock motherboard
I created USB bootable repair media. Diskpart tells me that each is MBR formatted, not GPT.
These were created on a Win10 machine.
One USB contains WinPE alone. I can boot it on my Lenovo Thinkpad, but cannot boot on my desktop that has ASRock H170M Pro4 motherboard.
Another USB was created with Macrium Reflect and it contains some version of WinPE, but seems incomplete (in particular I do not have MBR2GPT.exe). This USB will boot on either machine.
The WinPE boot failure on the ASRock system goes like this:
- I am give a choice of either USB or UEFI:Partition 1 for the USB drive.
- If I choose USB, it hangs and does nothing.
- If I choose UEFI, then it just comes right back to the boot choice menu.
Can anyone give me a clue why a perfectly good USB drive with WinPE will not boot on one machine, but is OK on the other?
