Some people have reported that the QEMU button in RMPrepUSB does not run on their system. This may be because I am using the qemu-system-x86_64.exe version 0.15.1. The latest version of RMPrepUSB in the Beta Downloads section uses qemu.exe and may give better results.
So far, I have not been able to make any version of QEMU boot a WinPE 64-bit iso, which is rather disappointing...
If you are having trouble getting QEMU to run after trying this new version, please let me know and let me know what OS you are running, etc.
P.S. The most common problem is that you are assigning too much memory to QEMU, untick the 'No User prompts' checkbox and select a smaller size of memory when you run QEMU (e.g. choose 900 instead of 1300). If that still does not work and QEMU does not launch, reduce it even more.
