Hi all, I would like to reuse my old iMac (mid 2010 version) by installing Windows 10. However, I learnt from Apple that the installation of Windows 10 is supported by Bootcamp 6 while my old iMac can only use Bootcamp 5. Does anyone know if Bootcamp 5 can also use to install Windows 10 in iMac mid 2010 and tried that before?

Also, the dvd reader of my iMac got some problem that the disc reading is not reliable. Can the Windows 10 be installed by using a USB drive instead?

It’s a few extra steps but it’s definitely possible to install Windows 10 on your machine.

Save yourself a lot of hassle and buy a $5 replacement dvd drive, use boot camp to install win 7 from DVD and upgrade to win 10 or suffer a world of hurt with no audio through imac speakers. You will encounter black screen at login occasionally, just hard reboot and you should be good.

It looks cool and seems everything can run smoothly even using Bootcamp 5.

I thought you said your DVD was unreliable?

Sometimes it cannot read the disc so I dont't know if it is the drive problem or disc problem. See if it will work well during the installation.

I downloaded the Windows 10 ISO and just discovered that a double layer DVD is required. So I tried the installation by using USB boot (only the MacOS and USB EFI appeared on the screen after pressing the Option key) and it kept saying the partition is not allowed for the installation (something about EFI and GPT).

So it seems the installation could only be made by using the installation DVD instead of USB, correct?

If you use USB you will have issues with Audio as I stated earlier, you should instal win 8 or 7 and upgrade.
If you don’t mind issues with audio then by all means use usb. Delete all the partitions in the win 10 installer and try again.

No it's not correct. You can use the USB to install Windows.
It's about the number of partitions in your internal drive. Windows cannot be installed to a volume number n with n bigger than a specific value.
That's the reason why when you use BootCamp Assistant to create a Windows partition within Mac OS, it will split your current drive in half.
You can also do a more complicated process like below:
1. Install windows on another PC, single volume SSD.
2. Delete the EFI partition on that SSD, if any. (If you plan to dual boot Mac OS and Windows on the same machine, if not, keep the EFI partition)
3. Move the SSD to the iMac.
4. Boot Windows on the iMac. Use OpenCore Legacy Patcher boot menu to select either Mac OS or Windows Partition.
5. If possible, by all means, do not install both Windows and Mac OS on the same physical disk.
