Oct 12, 2015 3:30 AM in response to andyward82by ceoofrad,Use these steps to choose a startup disk with Startup Manager:
- Turn on or restart your Mac.
- Immediately press and hold the Option key. After a few seconds, the Startup Manager appears. If you don't see the volume you want to use, wait a few moments for Startup Manager to finish scanning connected drives.
- Use your mouse or trackpad, or left and right arrow keys to select the volume you want to use.
- Double-click or press the Return key to start up your Mac from the volume you select
Choose the USB in this startup manager and then it will install windows.
I hope this helps.

Oct 12, 2015 4:26 AM in response to ceoofradby andyward82,Hi.
I tried to pick a different startup disk on the system preferences before restarting but there was nothing there other than the mac startup disk. I don't think bootcamp partitioned my hard drive properly.
I'll have a go at what you're suggesting there and see how I get on.
Thanks!

Oct 12, 2015 5:09 AM in response to andyward82by Loner T,Your iMac can install Windows using an external Optical drive or a USB installer. You need to use a USB2 flash drive, USB3 and generic flash drives do not work.
Please see How to install Windows using Boot Camp - Apple Support .

Oct 12, 2015 5:36 AM in response to Loner Tby andyward82,Really? So, the USB drive that was supplied to be by Microsoft (I'm assuming USB 3) won't work?
Wow - how wonderfully inconvenient.
Why on earth have Apple made this the case? Doesn't seem to make much sense to me...

Oct 12, 2015 6:26 AM in response to andyward82by Loner T,Your iMac (21.5-inch, Late 2013) - Technical Specifications has
Connections and Expansion
- SDXC card slot
- Four USB 3 ports (compatible with USB 2)
- Two Thunderbolt ports
- Mini DisplayPort output with support for DVI, VGA, and dual-link DVI (adapters sold separately)
- 10/100/1000BASE-T Gigabit Ethernet (RJ-45 connector)
- Kensington lock slot
If the Windows Installer does not have appropriate drivers, USB3 devices do not work. This is a Windows Installer issue, not a hardware issue. W7/W8.1 installers do not have such drivers. If you bought W10, test it. The USB3 W10 is not an ISO, it is an installer.

Oct 12, 2015 7:28 AM in response to Loner Tby andyward82,Hi thanks for this, however I'm still without a definitive answer.
I'm aware of the slots on the back of the mac and what they are - that's all understood.
SOoooooo, it's not going to install from the Windows USB that I purchased. That's fine - the serial number/activation key/whatever is what I paid for pretty much.
So, as an alternative, I have already downloaded the official Windows 10 ISO from Microsoft and was going to go through this to install.
Would this work?

Yes, it will work. Use BCA and start the process using a USB2 flash disk. Please post any issues you see. If you see a GPT v MBR issue, it can be easily corrected.

Oct 12, 2015 11:30 AM in response to Loner Tby andyward82,Right, well I've had a go and I'm having a trouble.
I got a USB drive (2.0) and wiped it as FAT. All fine.
I took the windows 10 ISO downloaded from the Microsoft site.
I've tried to install it and now I have this issue - see attached.
Can anyone help me?I've not even got Windows installed and already I'm sick of PCs.
It's saying it needs to be Windows 7 or later yet clearly I have a Windows 10 ISO!!!!
HELP!!!!!

Oct 12, 2015 11:44 AM in response to andyward82by Loner T,Do you have any pending Software Updates on Yosemite?
-
Oct 12, 2015 11:48 AM in response to Loner Tby andyward82,Nope. I'm on El Capitan too.
I've gone back, taken Windows partition off of the mac and have started again from scratch - this time with the Windows ISO.It's in the process of "Downloading Windows support software"
I shall keep you updated..!

Oct 13, 2015 5:16 AM in response to andyward82by andyward82,So, here's what happened in the end.
It all seemed to go to plan. The windows logo appeared and the setup dialogue box came up.
It asked me what partition I wanted to install onto. I didn't know the answer. So, looking at them - one of them was around 35gb (roughly the same as my BootCamp partition) so I assumed it was that. So, I formatted it and sent the installer on its way. It got to about 90% done and a message that had the word "locale" in it appeared and then uninstalled everything.
Once that was done it tried to restart but I'd seemingly wiped the OS from my hard drive so I had to re-install it.
So, back to square one really.
What partition should I have used?
Why isn't there any mention of having to choose what partition I want it installed on?
This is an absolute pain in da bum! -
Oct 13, 2015 5:59 AM in response to andyward82by Loner T,This link - https://help.apple.com/bootcamp/assistant/6.0/ - may help.
1. Which OS did you wipe - OS X ?
2. Since you already have the installer USB built once, you can use it again, and use the last option in the BC Assistant, Install (or Remove) as necessary.

Oct 13, 2015 7:00 AM in response to Loner Tby andyward82,Seemingly I did, yes.
I assume there are 'invisible' partitions on the drive and I chose the wrong one.
I'm happy to wipe the partition and start again but i'm worried I'll pick the wrong partition again.
Do you know what the partition will be called?
