Installing Windows 10 on a mid-2010 iMac

Hello!
I'm trying to install Windows 10 on my mid-2010 iMac without using Boot Camp. I can create a USB stick and partition, but it crashes during the Windows setup when I connect to the Microsoft account. Can you help me?

Hello,
According to this Apple page, your Mac needs to be relatively recent in order to install Windows 10 via Boot Camp, and that’s why I understand you're not going through Boot Camp.

I have a request regarding the USB key. It would be great if you could let us know:
• how you created it
• what this USB key contains: an ISO of Windows 10? a Boot Camp-style installer? ... something else?
• what it is supposed to do: install Windows 10 in place of macOS? keep macOS and create a partition for Windows 10 (like the Boot Camp method)? ... something else?

My opinion on your issue is this:
Part of your iMac's hardware is unknown to this installer and/or to Windows 10.
It could be any hardware component of your 2010 iMac (graphics card, USB component, Ethernet, ...) that Windows 10 has never encountered.
Consequence: not having the required drivers for each element of your hardware, the installer and/or Windows 10 crashes.
Note that Boot Camp installs drivers for Windows developed by Apple according to the Mac, hence the importance of using Boot Camp. Depending on your macOS version, maybe you could install Windows 7?

Hello and thank you!
I booted my USB drive with Rufus software on my Mac using Parallels Desktop. The USB drive contains an installer to install Win 10 on a partition of my Mac.
Since it was crashing during the Windows setup with a USB drive, I decided to go this time with a DVD on which I burned a Win 10 ISO. I noticed that the partition was formatted in GPT and that it needed to be formatted in MBR. Could this be the problem?

Every time I want to format a USB drive or a hard disk for mixed use (MacOS and Windows), I choose either the MS-DOS(FAT) format or the exFAT format (these are the only ones compatible with both Mac and Windows for reading and writing) and then I select the MBR option.

Yes, but the problem is that I cannot format a partition of my Mac to MBR.

To validate your procedure, you could conduct the following test: install Windows on an external hard drive. If you successfully complete your procedure, that will already be an important first step.

But how do I delete the partition I created for Windows from my Mac?

Hello,

Config: mac2010/OCLP Monterey

BootCamp partition

To install Windows with the GPT/MRB error, simply delete the concerned partition during the Windows installation without formatting it to continue the installation. I installed Win10 without any problems, but I couldn't manage to install a driver for the graphics card not supported by Win10. The installed driver is a standard driver. The WiFi works.

The deletion of the partition is done with the Apple Disk Utility (or BootCamp, I believe).
