Any help would be greatly Appreciated.Īlso, when I tried just running the setup from the ISO that was on the BOOTCAMP partition (instead of pointing it to the flashdrive), it gave me the same error. I have even tried using the Windows Media Creation tool to make a USB drive, and copied the BootCamp5 contents over to it, but when I try to load the AutoUnattended file, nothing happens, not even a new setup window. I have used older versions of the Windows ISO on the flash drive, but every time I start the setup I get the same error. First off, the USB and the Bootcamp partition are ExFat, so they won't have the 4gb limit. It says '0x8007000D windows cannot open the required file D:\sources\install.wim make sure all the files required for installation are available.' I have tried several things to fix this problem. Right after I type the command, I get the error. Then, you type in the command that points to your USB flash drive to initiate the setup. From the guide mentioned, it seems you boot into the Windows 10 setup that you loaded to your Bootcamp Partition. I am following the guide here How to install Windows 10 into a 2011 iMac without using the Boot Camp Assistant, an optical (DVD) drive or third party tools? and everything appears to work until I actually install Windows 10.
