Installed a new Samsung 860 EVO 1TB SSD in my Late 2014 iMac. I can’t seem to get Windows to install with bootcamp.

I have ran bootcamp, created the partition and bootable USB, but when I boot from the bootable USB, i get and error saying the partition is of the GPT type and windows cannot be installed. I have tried erasing and formatting to an Ex-Fat in Disk Utility, but that yields the same results.

What MacOS version were you using prior to changing the drive? Maybe it is a firmware issue?

Have you tried different USB drive? Certain drives have issues with boot camp.

I was/am using Mac OS Mojave.

I am thinking the drive may be the issue, it’s a WD Passport that I think it’s for Windows(not sure if it is or isn’t Mac compatible).

In my experience, Macs usually do not have have drive compatible issues, but this could be it.

Maybe try a different drive, sometimes certain drive have issues with booting and/or boot camp.

I had two Sandisk thumb drives, both the same storage size, and formatted the same, but they were different models. One wouldn't work with the boot camp set up, but the other one did. I also couldn't boot MacOS from one of them, but the other one worked fine as a boot drive.

I unintentionally wiped my SSD last night and had to reinstall Mojave. Now when I try to do Bootcamp it says the USB cannot be create because there isn’t enough space. I have tried an 8GB and 16GB, both yielded the same result.

I think I remember a boot camp bug about not being enough space. Have you tried to manual copy your Windows install files?

Open the iso for Windows, and select and drag all the files onto a disk that is formatted in XFAT. Or, you can burn the iso onto a DVD. Just mount a blank DVD, right click on the iso, and click "burn to disk". Choose the advance option, I think it is a drop down arrow, and pick the lowest burn speed.

I can't remember what exactly to do with that boot camp bug, I only read about it, but, one of the above methods might work.

When I get home, I can probably look up.

I would really appreciate if you could. Thank you for your help!
