If not, please update first.īoot Camp Assistant no longer supports cMP and doesn’t allow creating a separate partition for Windows. It’s supposed that you have the latest Boot ROM version 144.0.0.0.0.

This guide is for those who want macOS Mojave + Windows 10 + modern GPU (in our case Sapphire Radeon Pulse RX 580 8GB). What is more, none of them supports displaying of boot menu with 4k 60hz monitor connected. Well, some EFI bootable cards that support boot menu exist but they are released almostġ0 years ago and are really outdated. Supported, but it’s completely possible though not quite easy.Īnother challenge is that macOS Mojave 10.14 now implies using Metal-capable GPU while most of them are not able toĭisplay Apple boot menu (which you normally see holding the Option key) required to boot into Windows. Installing Windows is no longer officially It’s prettyĭisappointing considering how capable and upgradable these machines still are.

(4) If (3) is not the problem and you really want to try boot camp, after booting back into MacOS - if you've never actually gotten into Windows there should be no data worth trying to preserve in the windows partition - you can go into Disk Utility, delete the Windows partition, give back to MacOS the entire disk (don't just leave unpartitioned space) and then try again from the start.Classic Mac Pro 5,1 (or simply cMP, also 4,1 upgraded to 5,1) is now considered by Apple as vintage.

If the Windows install USB was created correctly then when holding down the "opt" key on boot, with the USB drive plugged in, there should be an option for "EFI boot" on-screen, selecting it will start the USB drive Windows installer. If the Windows installation USB drive was created correctly, then the problem would be that the Mac for whatever reason (was it unplugged?) did not boot from it and instead tried to boot from an "empty" Windows partition. (3) My suspicion based on your post not mentioning anything about going through a Windows install, is that after the bootcamp assistant made a partition for Windows to live on in your internal drive, it wanted to hand over to a "windows installation USB drive", but that never happened for whatever reason. (2) the black screen with "no bootable device" means that your Mac's firmware handed off the boot process to your Windows partition but there is either no Windows bootloader installed or the Windows bootloader is corrupted somehow. You should be able to click on your MacOS partition within that preference to select it for boot - after you do that ("authenticate" yourself with your password first) you should boot straight into MacOS thereafter without needing to hold down Opt to select every boot (1) You did not mention anything about going to "System Preferences" from within MacOS to select the startup disk.
I never tried Bootcamp before and it seems like the universe doesn't want me to, so I would love some solutions to this problem if you have them. However, it seems like now that my Bootcamp is over and that I have a Windows partition on my device, every time I start the Mac holding the option key to go to Windows, the same message comes back on the screen.ĭespite countless hours searching through the internet for a solution, and despite having read other Mac users having the same problem over the years (on Reddit, Apple Community, StackExchange.), I couldn't find a valuable and WORKING solution to this problem and that is why I'm asking begging for your help on this problem. Of course, what I did was restart my Mac holding the option key and I safely came back to my MacOS.
Once the Bootcamp app on my Mac completed the procedure, the computer restarted showing me a black screen saying "no bootable device insert boot disk and press any key". Because it's an older model, I also had to use a USB drive to perform the Bootcamp.
Ok so basically I am on a Mac Book Air Mid 2012 and I was undergoing a procedure of Bootcamp.
