New iMac Bootcamp Problems

Well, I got my new 2017 4K iMac from the UPS man today. Setup was a breeze. I just transferred over my time machine backup from my old iMac. No problems with Photoshop or anything else migrating over. Just had to reenter a few serial numbers.

I purchased the i7 version with 1TB fusion drive and Radeon Pro 560 GPU. Excited to try a few games from my Steam library, I attempted to install Windows 10 via bootcamp... and started having a problem. Seems the Anniversary Edition of Windows 10 does not play well with Bootcamp right now. I am currently trying to install an older build of Windows 10. Fingers crossed it will work.

I am pleased so far with the new iMac. The screen is noticeably sharper and brighter, with more intense colors. It is only a subtle difference, but it is noticeable if you look closely. The i7 processor is snappier than the i5 I've been working on, and the Fusion drive is wonderful, considering I had been working with the 5400 RPM HDD that came with my old stock iMac. I wish I could have afford an SSD but my budget would only allow a Fusion Drive. But I am pleased with the speed on the Fusion Drive. Everything loads up really fast. Hopefully I'll be able to get Windows up and running soon so I can report on game performance to you guys.

It's not a problem with Bootcamp. From my research, there is a bug in the Anniversary Edition of Windows that is giving Mac owners issues. Effin' Windows...
[doublepost=1497466318][/doublepost]Nope. Older build won't install either. It keeps saying it cannot see the partition to install Windows in. Does anyone have any idea what I can do to get windows installed. I really wanted to play some games.

Think I've got it. I installed Creator's Update and disconnected all external drives and the install is almost finished.

No, they do, they just can't work with the SSD portion, so the OS and any apps will only be designated to the slower spinning drive portion.

Good point. I was thinking though he was attempting to install on the SSD portion which is something I know I looked into doing before(no luck obviously)

Well, I'm a little disappointed. I got Windows installed. Installed Steam. Downloaded and installed Street Fighter V and I could only get it to run properly at 1600X900 resolution at high settings at 60 FPS. 1080p would only run about 54 FPS on medium settings. It looks good, really, and I can live with it, but I was really hoping for a bit better performance from the Radeon Pro 560. I was only expecting to get 1080p so it is a bit disappointing to have to drop that a tad.

It could be a combination of slow hdd + not optimized graphic driver.

Not sure if this'll work on your GPU but it's worth applying the latest driver through the AMD Autodetect tool: http://support.amd.com/en-us/download/auto-detect-tool

If it finds a newer driver and you install it, you're likely to increase graphics performance. Again it's not a definite if it'll find a driver but it's worth a try. As @gian8989 rightly mentioned, performance may also be impacted due to the HDD bottleneck. :)

I don't think you can update the AMD drivers within Windows. Apple Update might have newer drivers, however. You can also use MXDrivers.com or BootCampDrivers.com for third-party modified drivers.

I am going to need the official Apple drivers before I can begin to implement the newest 500 series cards. Can anyone with a new 2017 iMac upload their WindowsSupport.dmg package or maybe just the AMD drivers within in particular to googledrive or dropbox for me to download and implement the newest iMacs into my driver packages at bootcampdrivers.com? Thanks!

I have a 27" iMac, with the AMD Radeon pro 580 8go vram. I downloaded the windows support files from bootcamp utility. Here is the download link for you (wetransfer): https://we.tl/tB5CUcPuHT

ok so early releases of updated drivers for the new iMac 2017 and MBP 2017 are now available. Would appreciate feedback on them so I can improve stability etc. in future versions.

Agree. If you must Windows Game on a Mac it's best to have an external Boot SSD. Especially with a USB 3.1 or TB3 connector these days. :apple:
Are you saying that you can use bootcamp to install windows to an external drive on the new iMacs?

I have a 2017 iMac and using an external SSD samsung t3 for bootcamp and my games. It's working flawlessly. Very happy with this solution. This way I save a lot of disk space on my internal 512gb ssd.

I thought there was an issue with using bootcamp on an external drive. Does anyone have a link or guide on doing this? I could have swore I did a ton of research on doing this a couple years ago.

Has anyone got any written down instructions on how to get Bootcamp to work on an external SSD on a 2017 iMac (with no Windows machine)...

I tried following these instructions last night:

https://apple.stackexchange.com/questions/218105/is-it-possible-to-use-boot-camp-with-windows-10-from-an-external-hdd

However when booting the mac with the alt key held down, it didn't see the Windows USB SSD...

I might try these instructions next:
