<Image Install> Bootcamp Error

Sorry, try

md5

hit space, then drag the file over and execute the command. Should be something like this

md5 big_huge_file.iso

with a result of

MD5(big_huge_file.iso)= 20665acd5f59a8e22275c78e1490dcc7

Looks good. The ISO is clean.

• Re-run BC Assistant and try to install Windows.

• You will need two different USB flash drives, which should be USB2.
• Using BC Assistant Action -> Download, get the Windows Support Software for W10.
• On the Windows PC, build a USB Installer using Windows Media Creation Tool.
• In Disk Utility. create a FAT partition, of the size you want Windows to be.
• Connect the USB installer and reboot and hold Alt/Option. Choose the Windows icon from the Orange USB and try to install W10.
• If the W10 installation is successful, you can install the Bootcamp drivers using setup.exe from the second USB.

You will need to use macOS Terminal. Here is an example.

Macmini-i18:Downloads $ ls -lgh *.iso
-rw-r--r--@ 1 staff   5.1G Oct 20 11:32 Win10_1909_EnglishInternational_x64.iso
-rw-r--r--@ 1 staff   5.7G Oct 31 12:07 Win10_20H2_English_x64.iso
-rw-r--r--@ 1 staff   5.8G Dec  5 16:54 Win10_20H2_v2_English_x64.iso
Macmini-i18:Downloads $ openssl md5 Win10_20H2_v2_English_x64.iso
MD5(Win10_20H2_v2_English_x64.iso)= 10d50d88fac6306a00ddb41e983a046b

Did you follow the standard installation steps as noted in Install Windows on your newer Mac using Boot Camp - Apple Support?

Can you post the name and MD5sum of the W10 ISO?

You need to run the openssl md5 command in the same directory where the .ISO is located.

What is the year/model of your Mac (do not post the serial number)?

What is the current macOS version?

I watch YouTube tutorials on how to install Bootcamp and the method they were using is the one that I used and it doesn't seem to work for me.

YouTube videos may show a different model then yours, and are of questionable value, in very specific cases. If you followed the standard BC installation, it is the least problematic.

Can you run this command?

openssl md5 Win10_20H2_v2_English_x64.iso

Type

ssl md5

but then instead of finishing the code drag the .ISO file into the terminal window, then run the command

Even when you drag the .ISO into the Terminal window?

Do you see an OSXRESERVED partition in Disk Utility?

When BC assistant is running an OSXRESERVED partition pops up, but then when it fails the download and my mac restarts, OSXRESERVED is no longer in disk utility.

Which 'download' fails? Bootcamp Windows Support Software?
