No drivers were found

1. What is the year of your MBA?

2. When you run BCA, do you see a OSXRESERVED partition created?

Can you run the following two procedures

Resetting the System Management Controller (SMC) on your Mac - Apple Support

How to Reset NVRAM on your Mac - Apple Support

and then try BCA again?

Have the same issue on a brand new MacBook Air. Just started, did a OS X update to 10.11.1, ran boot camp assistant. My guess is some incompatibility with the Win10 1511 ISO. Is the previous ISO still available somewhere?

It is a good sign to see OSXRESERVED. Where is it failing?

I downloaded the non-1511 ISO yesterday from the M$ website.

Found a regular Win10 non-1511 ISO as well. But same issue. It doesn't say which drivers are missing either in the Windows Setup. Really hard to dig deeper into the issue.

The missing drivers message seems to be erroneous. You can see OP is now able to get OSXRESERVED to come up. Are you using a Wired connection when BCA downloads the support software? Can you manually try this and see if it works without any errors?

Please ensure you meet Requirements for Software Update Service - Apple Support .

"OSXRESERVED" is no problem. BCA works fine. All partitions are there. Drivers are downloaded and stored on that temporary partition as well. The error appears when the Windows Installer is about to start. Here is a similar image:

Is this is the exact image? OP has a different screen image of the error. There are two separate unrelated problems. In your specific case, The downloaded ISO is corrupt. Please verify the checksums.

Yes! I have exactly that problem

No. You have a completely different issue. The CD/DVD error is not the same as the "No drivers found" error. Exact error messages can help narrow down the problems much quicker. When you see this error message, click OK, select Browse, select your USB -> Bootcamp -> Drivers -> Apple -> AppleSSD.sys. This may also exist in $WinPEDriver$ folder. Please verify and choose the correct location.

No this is some pic from the internet that was just suppose to show at which step this happens. Because you were always thinking of OS X problems or BCA errors. It does in fact look like the image from TL1012.

It's nice you are trying to help but clearly you don't know much more about this specific problem as we do. I hope someone who experienced this as well and found a solution will jump in.

Btw. I tried to install Windows from a USB drive as well now (created with the MS Media Creation Tool). It's a little different and might hint at what's missing. With the USB drive the setup goes a little further until you can select the partition you'd like to install Windows on. But it won't show any partitions nor any hard drives there. I'm on a 2015 MacBook Air so my suspicion is that the driver for the built-in flash drive is missing. It won't load any drivers from the downloaded bootcamp driver package either.

Ok I take my last comment back. You do know a think or two about this one 🙂

It's indeed the SSD driver. Not sure if it is somewhere on the temporary partition - I just downloaded the package separately and put it on another USB drive. It was then located at: WindowsSupport -> $WinPEDriver$ -> AppleSSD64 -> AppleSSD.sys

Thanks a ton!
