It is stopping you from using the DVD, because it incorrectly detects it as a W10 DVD. The problem is not the steps you are executing, but High Sierra's BC Assistant on a 2011 Mac. Was I supposed to burn what's on the thumb drive onto the DVD too? What are we still doing wrong? This is a list of files on the thumb drive: I opened the DVD and this is a list of files on the DVD: Insert your Windows installer disk and wait a few seconds for the disk to be recognized." We inserted the DVD and nothing happens.
It told us: " The installer disk could not be found. We ejected the DVD and tried clicking the continue button on Boot Camp Assistant.
Please use a DVD or USB drive which contains Windows 7 or Windows 8."
We get this message: " Windows 10 is not supported on this Mac.
Going back to Boot Camp Assistant, we had already downloaded the support files to the USB thumb drive, and with the box for Install Windows 7 or Windows 8 checked, we clicked the continue button. I did not give it this name, this is the name it gave itself. When mounted to the desktop the disk shows a name of: IR5_CCSA_X64FRE_EN_US_DV9. Since that matched the number you provided in the reply above, I went ahead and burned the ISO file to a DVD. Openssl md5 /Users/xxxxxxxxxxxxxxxx/Desktop/Win8.1_English_圆4.iso The file we downloaded from Microsoft is named: Win8.1_English_圆4.iso
Transferring OS-specific files will cause issues with Windows on Mac due to driver of conflicts. I suggest looking at Move your data from a Windows PC to your Mac - Apple Support. You should only transfer non-OS files from the Dell PC to the Mac. Please post the filename/MD5 before you Burn, otherwise you will waste media. The largest file is install.wim which is about 3.6GB. The ISO file itself is larger than 4GB, but the entire file is not copied to the USB2, but it's contents. We also had to change the format to exFAT from MSDOSfat32 because the ISO file is larger than 4.0 GB. Post the ISO file name and its MD5sum before you burn it to a blank DVD. We did download the Windows 8.1 ISO file directly from the Microsoft site. On a separate note, when we get Windows 8.1 up and running on his iMac, do we just copy his old files and programs from his Dell PC onto thumb drives and transfer all that info to the Windows partition that way? Thank you so much! It might be a day or two before I can give it a try with the holiday coming up. We will set it to burn at the lowest possible burn rate speed. I have some DVD-R discs, and I'll take my 2009 MBP over with it's SuperDrive just in case. We also had to change the format to exFAT from MSDOSfat32 because the ISO file is larger than 4.0 GB.Īccording to MacTracker, his mid 2011 21.5" iMac should have a SuperDrive to burn the DVD. I used one of my USB 2.0 drives and corrected that. Uncle had just bought a USB 3.0 thumb drive, and we were having problems.
