Q: Mid-2015 iMac won't reboot into Windows 10 install
hi folks,
I have a brand new, mid-2015 Retina 27" iMac.
I'm trying to install Windows 10 (or, really, any version of Windows) on it via Bootcamp in a dual-boot scenario, so that I can do some gaming via Steam.
I have downloaded the latest Windows 10 iso from Microsoft.
Bootcamp Assistant partitions the drive, but when it reboots, it does not go into the Windows 10 installer. Instead, there is a delayed booting period, and then it dumps me back into Mac OS X. Holding down option does not show a Windows 10 bootable option. However, the drive has been partitioned -- the Windows partition shows up on the desktop in Mac OS X and in Disk Utility.
I know that Microsoft recently updated the Windows 10 isos, and I suspect what is happening here is that Bootcamp Assistant has not yet caught up.
I also suspect this problem is quite widespread.
Can anyone let me know what I should do? I also have a Windows 7 disk, but Bootcamp Assistant tells me I need Windows 8 minimum ... and Microsoft no longer sells copies of Windows 8.
Kind regards,
Renai
iMac, Windows 10
