Having Trouble with Boot Camp Assistant

[Irishman]

I've used it successfully for a year of dual-booting some years ago, but I'm having issues this time. I'm on Mojave, same as last time. Same late 2012 iMac as last time, too.

I'm even re-using the same USB stick from last time (the one that worked), and made sure to download the latest Windows 10 64-bit iso.

I'm not making it to the Boot Camp Assistant screen where it asks you to drag to set your partition size. The Assistant seems to get me through the long part of copying Windows files from the ISO file to the USB stick, then asks me for my password twice, then "quit" is the only option.

I've tried three times last night.

Any ideas?

Haven't you forgot to check "Install Windows 10" when you created your Windows 10 USB key ?

Install Windows on your older Mac using Boot Camp

Older Intel-based Mac computers require an external USB drive to install Windows on your Mac.

if it's not in these directions, then nope.

 

[Antares23]

It's not but you should otherwise it won't get you to the partition screen.

Is that a check box I'll get in Disk Utility?

 

[Antares23]

No, when you go to BootCamp utility, you need to check it when creating your Windows 10 bootdrive
It's the third one, you need to check all of them basically

thanks.

To answer your question, I made sure all three tickboxes were checked, each time I tried to run Bootcamp Assistant.

Any other ideas?

Create the partition yourself then in disk utility, then boot to the Windows 10 USB yourself
Keep option key pressed after the bong and boot to either "EFI Boot" from the USB key, or "Windows", I think you should have both and one of them should work
I installed Windows 10 yersterday on my 2013 MacBook Pro like that and it worked so far

Well, that doesn’t answer my question about why it’s not working through Bootcamp Assistant?

 

[Antares23]

Does it matter ? As long as you manage to install Windows why bother ?

 

[Irishman]

Well, mostly because I'm not used to doing it any other way than via Bootcamp Assistant. What you're describing is Greek to me

 

[Antares23]

Oh okay sorry, I'll try to make it easier to understand, I wrongfully thought most poeple here were kinda tech-savy

0) Go to disk utility
1) Select your SSD (not the APFS container)
2) Click on partition
3) Click on +
4) Add a FAT/exFAT partition
5) Click on apply

Then reboot, press option key after the bong, choose your windows 10 usb and procceed to the installation

Hope it's been clear enough

Sometimes BootCamp can be a bitch and you gotta do things yourself

 

[Irishman]

II'll let you know if I have the guts to try it your way.

Thanks again.

 

[Antares23]

You should try it, it's not as complicated as it seems

what is the size of Windows ISO? I heard a lot of complaints about recent Windows 10 ISO, which is bigger than previous editions.
