I can't install windows 10 because broadcom virtual wireless adapter driver is incompatible. In another thread, one moderator, Chris M, say:
"Per the FAQ on the Windows 10 board, regrettably, there will not be any concrete data until 7/29/15."
Now is 08/13 and still no reply. Can you help us?
You may want to check out this thread where people have posted a work around for the Windows 10 compatibility issue with the Broadcom Virtual Wireless Adapt....
Follow the instructions posted in that thread on how to remove the software, without removing the driver, and you should then be good to go for Windows 10.
