MP 1,1-5,1 Windows USB Installer Fails every time, OC 0.7.3

[coh998]

Mac Pro 5,1 with OC 0.7.3, trying to install Windows 10 to SSD using bootable USB installer made with Rufus or Media Creation Tool (doesn't matter which) and two different Windows iso's. One purchased and dowloaded separately, and one downloaded with the Media Creation Tool. Again, it doesn't matter which, the install fails at the same point, either just after deleting all partitions on the destination SSD and selecting the remaining "Unallocated Space" partition for install. The installation fails right after that, sometimes instantly, sometimes after "Preparing files" for a bit...

Any ideas why the Windows Installer would always fail during or just after the drive format stage?

hi, in my case I always got an error using UnetBootin or DD the iso in terminal.

The usb is fat32 formatted and Install.wim is bigger than the fat32 supported 4GB so i had to split it (using wimlib)

Thanks. I haven't had any trouble creating the USB installer or booting from it. But the setup fails just after it formats the target SSD.

Yes completion of creating the usb stick it is not the problem. But to check if you have the same problem as I had can you check if the Install.wim on your fat32 usb stick is the same size as in the iso if you mount the iso?
