BootCamp Assistant Not Working on New 2019 MacBook Pro 16 Inch

All the 2019 Macs are UEFI Macs, which can boot from a vanilla W10 ISO, but you may have to wait for Apple-specific drivers for any Apple-custom hardware. If someone has a PC, create a USB2 Flash drive via Windows MCT and boot from the USB. You may need to disable Boot security.

See

• About Startup Security Utility - Apple Support
• About Secure Boot - Apple Support

for reference.

AMD should have WHQL drivers for the GPUs.

Did the steps above, but the installation stuck at "couldn't find any drives", even though I've already partitioned a exFAT image for windows installation. Problem similar to this: https://discussions.apple.com/thread/8419542

The storage is Apple-specific. This is provided by drivers, which Bootcamp Assistant puts in $WinPEDriver$.

even though I've already partitioned a exFAT image for windows installation. Problem similar to this: https://discussions.apple.com/thread/8419542

Can you use Brigadier and download drivers for MacBookPro15,3 and just copy the $WinPEDriver$, AutoUnattend.xml (not the Bootcamp folder) to Windows MCT-created USB's root and retry booting from the USB?

I think with newer MacBook Pros, any with the new T2 chip, you have to change the trusted boot settings in order to use Boot Camp and boot from USB. I had to even do this on my 2019 15" model, FWIW....

EDIT: Looks like this was just a driver issue based on other replies. Probably disregard my suggestion, then!

I have the new 16" MBPro, with 32 GB and 8GB Radeon Pro 5500M.

I was able to get Windows running on an external HD. I used WintoUSB (free) to copy the ISO to the external drive.

I then manually downloaded the drivers for Bootcamp using my MBPro 2019 15". After Windows installed, I manually installed all drivers I could.

The good.

• Most drivers are the same except for a couple of major ones.
• Keyboard and track pad will work, but only after you install the Bootcamp drivers. For install you need external mouse and keyboard

The Bad

• Wireless driver will not work
• Radeon driver cannot detect the new hardware (I have the Radeon Pro 5500M model, 8GB) However I was able to trick it to use the 5500M HD driver which seems to work (the resolution changed and the driver does not have any errors)
• Audio says its working but its not
• One other chip is not working, not sure which one

I added a USB Ethernet connection and did a full Windows update, scanned for new drivers, ran various other scans for the Radeon hardware, wireless and audio. No luck. If anyone knows the exact model of the wireless adapter, let me know and I will try to get it directly from Broadcom. I can't seem to find the exact model number.

It is a usable Windows system as long as you don't need audio, and have another wireless adapter you can plug in. Far from ideal, but it does work.

If anyone has any other ideas, let me know and I will try it.

Hope this helps.

This is what you should get...

<ProductManufacturer>Apple Inc.</ProductManufacturer>
		<ProductVersion>6.1.7745</ProductVersion>
		<ProductCode>{FCFFE6B6-BAE8-490E-88D0-097A9DA1C43D}</ProductCode>

and the file structure is

Brigadier also cannot find it the Apple catalog used for 2018 and older Macs.

./brigadier -o ~/Documents/BootcampDrivers/MacBookPro16.1 -m MacBookPro16,1
Using Mac model: MacBookPro16,1.

Couldn't find a Boot Camp ESD for the model MacBookPro16,1 in the given software update catalog.

Apple needs to upload the drivers to the existing catalogs in their CDNs.

Just want to post that this is an issue for us on multiple new MacBook Pro 16 as well. Boot camp is an integral part of our organization’s workflow and this is really bad support on Apple’s part.

This stuff should work out of the box on day one.

Very frustrating!

Is there any other possible ways to install windows without bootcamp? For example using the drivers downloaded for macbook 15 inch?

I tried creating a windows boot drive. But on the step where it wants me to choose a disk to install windows on it says "couldn't find any disks."

Is there a way to solve this so I can get windows installed asap?

Can you test with the 15,2 BC drivers? You can use Brigadier to get them.

A correction to my earlier post: The drive only works on my 13inch macbook pro on condition that a windows partition is created by bootcamp. If I create the partition using disk utilities, The issue persists. I think this might be some issue related to partitions not being able to be read by the Windows installer driver?

The USB installer should be created by Windows MCT. The designated partition should not be an APFS volume. You can create it as FAT32 or exFAT partition.

I think this might be some issue related to partitions not being able to be read by the Windows installer driver?

If the installer is unable to see the internal disk, it will not be able to read any partition information either.

I have read all the posts and I am concerned. Our Company prefers MacBook Pros for our media work but must use Windows 10 for a number of very specific entertainment products. We decided to purchase a number of new MacBook Pro 16” high spec, but have frozen the purchase until we are sure BootCamp will successfully install. What is the timeline for proper support?.

Thanks

I spent about 4h trying to bypass this by manually making a USB installer drive, disabling boot protection, etc, and downloading the 2018 MBP drivers - Windows 10 couldn't see the SSD, so I loaded the WinPE drivers from a USB stick for the old SSD, and it saw it ... but wouldn't install on it. When I tried to reformat using Win10 installer, it did something, refused to install, and really screwed up the partition table to the point where Disk Utility wouldn't let me remove the partitions it created. Definitely suggest waiting for Apple to button this up...
