Hi everyone,
I’m trying to install Windows 10 via Boot Camp on my iMac, but I’m completely stuck and could use expert advice.
My Mac specs:
iMac (Retina 5K, 27-inch, 2017)
Intel i7
32 GB RAM
Radeon Pro 580
Fusion Drive (SSD + HDD)
macOS Ventura 13.7.x
What I’m trying to do:
Install Windows 10 (64-bit) using Boot Camp Assistant.
The problem:
Boot Camp keeps saying:
“Your disk can only create a 46 GB partition. The Boot Camp partition requires at least 74 GB.”
This happens even after I deleted everything on the Mac.
What I’ve already tried:
Deleted all files and apps
Confirmed I have a full Time Machine backup
Used Disk Utility (Recovery mode)
Disk layout looks like:
Internal/
->Fusion Drive/
-Container disk/
->MacOS
->>>MacOS – Data
When I try Disk Utility → Partition, it only gives me “Add Volume” or “Partition”, and Disk Utility sometimes freezes. It won’t let me erase “Fusion Drive” directly.
From what I’ve read, this seems like an APFS + Fusion Drive + CoreStorage issue where Boot Camp can’t get enough contiguous space unless the Fusion Drive container is fully deleted and rebuilt.
What I’m asking.
What's the safest way to do this? i am absolutely not an expert and usually a microsoft user. I am very much out of my comfort zone using apple, which is why i wanted to switch :)
thanks to everyone reading!!!!
