Winclone 9 and new iMac

Have a new 2020 T2 iMac - all SSD, of course. Still have the older one with Boot Camp. Don’t want to partition the SSD storage. Have v8, but will upgrade to v9 shortly. Will it allow a Boot Camp set up on an external drive, or is it a complicated procedure (as was before, involving making virtual machine set ups to start with)? Or, will v9 simply allow me to set up an external FAT hard drive, and v9 makes in into NTFS, puts my image and the Windows Boot Camp drivers (which I will have saved) and off I go? Presumably do Sysprep first on the older machine?


Gave up several months ago after numerous/varied attempts to migrate my MacbookPro 2018 WIN10 installation to a Samsung 860QVO SSD. Never took up tperfitt offer of WC8 refund, but will try again with Winclone9 if upgradable for $0.00

Winclone 9 does indeed support the new 2020 iMac and upgrade is free if you bought in 2020. Let me know how it goes.


Hi Tim,

I bought Winclone 8 on the 16th December 2019, so I guess I miss out on
the upgrade…

Also, you haven’t really answered my question. I already realised that
you support the 2020 iMac, but I was trying to ensure that I could get a
bootable Windows on an external drive, as I don’t want to partition my
internal solid state drive.

I see another poster has tried this, and has not succeeded, because he
cannot boot from the external drive, despite going through a few hoops.

I would appreciate a 1,2,3 sequence of every step I need to go through
to put my old Boot Camp set-up from my last iMac (which is still with
me) on to a bootable external drive (starting with an unformatted
drive), which will appear and boot from the “option” screen.

Oh! Thank you! That’s really good of you.

I’ll follow the instructions above on the next few days.

Regards, and stay well,


Have a new 2020 T2 iMac too. Now i run windows from an external usb SSD Sabrent Nano drive.
I cloned the bootcamp from my 2015 Imac using EaseUS Todo. Boots and runs well.
If you do cloned bootcamp installed on the new mac with SSD , do the following.
After backing the bootcamp uncheck the third partition apart from the Fat32 and Ntfs. The third partition is the Macos partition. Cloning the three partition will result in your external drive running with no sound, Wifi etc.

I’m sure Tim was delighted to see that you used a competitor’s product :wink:

I have also the 2020 iMac with T2 and had no luck with the cloning to the external SSD so far.
Inaccessible boot device message while booting windows 10. I followed all hints from Timothy but it is not working.

If have a solution please let me know!

This is what I used to fix the Issue: Bootcamp Inaccessible Boot Device

Not exactly a piece of cake, is it?

I actually think that Winclone should include built in scripts to accomplish some of these things, as one of the main points of owning it is for the transfer of existing Boot Camp set-ups… We really should not be expected to have to troll through forums or other postings, from some very clever individuals, in order to find quite complex methods (do-able, but hardly the sort of things the average user would ever know or think of - or even feel confident to try) to do these tasks. There should be options to simply transfer to a new Boot Camp partition on a new machine, or to an external hard drive, or external SSD. The scripts should perform all the necessary syspreps, and so on - making the whole thing a click or so on the old machine, and another click or so on the new one - and that’s it. Maybe it’s asking a lot, but that’s what the point of the software is - apart from backing up existing Boot Camp partitions as a safety net.

I absolutely agree. I hope it at least got your system working.
