Ruben has a Mac that he runs Windows in boot camp. He has an NTFS drive that he needs to read from time to time. When he reboots back into macOS Catalina, the hard drive partition isn't recognized and won't mount. Leo says it sounds like macOS has messed up the partition used to run boot camp. He recommends backing up the data, repartitioning the drive and then reinstalling Catalina. Look up FUSE drivers: it enables you to read/write NTFS drives in macOS.
Caller wants to dual boot into Windows with Boot Camp, but it's telling him that he doesn't have an Intel processor, so it won't work. He bought a used Mac, what gives? Leo says it may be that Mac doesn't have the most recent version of the OS (it's running El Capitan). Leo says to do a clean install of MACOS and do an immediately BootCamp installation. See if that works.
Ray wants to know if you can dual boot a Windows machine with Apple OS X. Leo says no. You can go the other way around and boot up to Windows 10 using boot camp, but you can't make a Windows machine run OS X unless you do a "hackintosh" setup, which is a direct violation of Apple's terms of service. Plus, Apple won't sell you a copy of OS X without a computer.
Bruce does both Mac and PC work, and he's looking for a laptop that can handle both well. Should he buy a PC centric computer that can run a Mac virtually? Or the other way around? Leo says that there is no way to run macOS on anything but a Mac, especially not virtually. He could do a hackintosh, but not on a laptop. So Leo says go the other way, and get a MacBook Pro running Windows in Boot Camp.
Danny left his laptop on while flying and when he went to open the laptop, the drive disappeared and he doesn't know what happened. Leo says it sounds like the drive had been jostled to the point that the computer couldn't read it. It could still be connected, though. It's likely that the disk catalog was damaged or corrupted. He could run disk utility, but Leo isn't all that confident that it will work for him. Drive Rescue could perhaps fix the problem. Disk Warrior is another.
Steven has an old MacBook Pro that has Windows 8.1 installed with Boot Camp. He'd like to dump Windows now and get that space back. Jason says he can open Boot Camp Assistant and click through to the partition utility and use it to remove the partition. He'll just need to click "restore." That will allow him to restore his Mac to its original configuration. Sometimes that doesn't work, though, so he can delete the Windows partition in Disk Utility as well.
Troy updated Windows 10 on his Mac and liked it so much he deleted macOS and now it's not working well. He's trying to reinstall it, but he can't. Leo says that's because he needs the Apple drivers through Boot Camp to run it. So he kind of has to have macOS on the computer, but he can shrink down the partition to as low as it can go. It could also be an issue with the EFI Master Boot recorder.
Mike is trying to use Windows 10 on his iMac with a Fusion drive and it won't take. Leo says that the Fusion drive causes issues with Windows 10. The key is to get the drivers from Apple. Mike tried those and they wouldn't load. Leo says that points to either a bad ISO download or a bad driver download. He should start over. Download the ISO and the drivers again and see if his luck improves. He'll also need the 64 bit version of Windows 10 to run in Boot Camp, and his Mac needs to be a late 2012 or newer.
Bruce has a 2012 MacBook Air bootcamped to start up with Windows 7. He keeps getting asked to upgrade. Leo says it is a free upgrade until July 29th. Will he have any problems doing it with BootCamp? Will he need new drivers? Apple has created drivers for Windows 10. What about registering it? Leo says that your computer is entitled to it and when you upgrade, it should just install and activate. Apple Support has an article - https://support.apple.com/en-us/HT204990
Carlos has been trying to upgrade to Windows 10 on his Mac and it keeps asking for a CD instead of installing with the ISO. Leo says it may be a bad ISO. Boot Camp Assistant will automatically install it. Microsoft will also allow him to download a Windows 10 ISO and it will verify the ISO to be sure it's valid. He can also use this app to download any missing drivers (thanks to Beastmaster in the chatroom).
