Just trying to install WIn10 x64 on Macbook Air - fully updated iOS and latest Win10 d/l from microsoft site (ie as of Aug 2019), and the ages old error of bootcamp not recognising the Win10 x64 ISO is back.
Any ideas as to how this can be resolved, or any news as to when iOS will be patched to fix this error?
Thanks
MacBook Air
From Install Windows 10 on your Mac with Boot Camp Assistant - Apple Support,
This is an oblique reference to a direct download, and the link will open a Safari window to download the ISO.
There is a better reference in Install Windows on your newer Mac using Boot Camp - Apple Support, which says

Thanks Loner T. File is windows.iso and was obtained following MS advice that the “best way would be using Windows 10 installer file:
https://www.microsoft.com/en-us/software-download/windows10
Then it will download and check the file integrity and if there is any problem, then it will notify you.”
I downloaded on a win machine to ISO, selecting Win10 / US / x64 options but also tried a variety of options including UK english, x32 (checking files were confused), etc.
None worked before I came to report it here.
will check md5 hash using certutil and will revert (though if it is really checked by the MS downloader this seems superfluous).
Hi Loner T, Yes I had read that in these discussions somewhere else. Files were downloaded over ethernet/fibre connections and transferred from PC to mac using pen-drives. The details of my file are:
Windows 10 US-ENG x64 (downloaded this week) - 4.42 GB (4,752,932,864 bytes)
certutil -hashfile I:windows.iso
SHA1 hash of I:windows.iso:
028dbebff6beab2ccc4a426cd6b452e44682aee2
CertUtil: -hashfile command completed successfully.
I can provide the hash of the other files I downloaded (eg UK english version).
For this file (being so large), I had format pen drive exFAT as classic FAT would not accept it). No issues noted when transferring from PC/pendrive/Mac
Thanks for your input
Another version I had attempted with was
Windows 10 x64 (also downloaded on 2 Aug) 3.88 GB (4,169,596,928 bytes)
certutil -hashfile I:windows.iso
SHA1 hash of I:windows.iso:
2de3c74022496a6b3263e7a5c296900b2c69b2ba
CertUtil: -hashfile command completed successfully.
To check whether there was some issue with the latest version of Win10 available for download, I tried with this verison
Windows 10 Pro x64 downloaded in Feb 2019 3.86 GB (4,147,445,760 bytes)
certutil -hashfile I:windows.iso
SHA1 hash of I:windows.iso:
98346e87fd969b3b76203d88230552b6d54a3429
CertUtil: -hashfile command completed successfully.
The ISO file name does not seem to be a retail version. Here are some examples.
openssl md5 *.iso
MD5(Win10_1803_English_x64.iso)= 986e2e17cf6b0b49141cd15699768e6e
MD5(Win10_1809Oct_English_x64.iso)= 7a19f70f948614b55b716a6ee0ca5274
MD5(Win10_1809Oct_Spanish_x64.iso)= 8cf07112c189819e26a50b0c675fe603
MD5(Win10_1809Oct_v2_English_x64.iso)= ab22088758dbc5a13247ffc64c36f9a8
Hi Loner T
Users downloading from MS site do not have an option as to which file name to select.
The download tool from MS -which must be installed on a windows os - is found here: https://www.microsoft.com/en-us/software-download/windows10 always names the file windows.iso.
The step by step process is shown in a word file here: https://drive.google.com/file/d/1lyv0jPWapjyg80Zt5feHiZHrxmVMwalm/view?usp=sharing
Maybe Apple needs the iOS to recognize retail versions provided by MS as shown above and not just specific filenames?
As an update, when downloading the Win10 file directly onto the Mac (ie safari on mac) the file names in the format you show above are generated.
Having done so (over wifi), the mac is now happily installing Win10 Pro, so the issue I have has been resolved.
The following work around has been identified, until such time that Apple updates the bootcamp installer and the support pages on this:
When installing Win10 via bootcamp on a Mac, the Win10 iso should be downloaded directly onto the mac that will have the Win10 installation on. Downloading on a PC using MS tool and transferring it physically to the mac is not compatible with bootcamp installation.
Hope others find this solution works for them too.
Loner T - thanks for the questions/guidance.
Indeed very oblique!
it would be good for iOS/bootcamp to recognise a valid Win10 download, even when one is downloaded using MS tool for PC’s...especially considering if the user is setting up Win on a mac he is probably using other Win based machines too.
all good and thanks again Loner T.
Excellent! Please post back, if you run into any further issues.
What is the name of the ISO file and it's MD5sum?
ISO files downloaded over wireless network have shown block corruption, which causes problems. WE should check the MD5sum.
As a test, from the macOS side, can you go to the MS Download website and try to download the ISO? Post the file name and the MD5sum.
bootcamp does not recognise win10 64 (again)
