Upgrading OptiPlex 780 machines to Windows 10 from 7

I know that Dell does not support the upgrade of the OptiPlex 780 machines to Windows 10 but I work for a small non-profit and we are moving to online products that require Windows 10 and I have to make it work.  We have ten of these machines and was hoping that others have done this already and can tell me the pitfalls/fixes.... is there anything I should do first... Bio version? Chipset? etc. I have already upgrades a Latitude E6410 and there were a whole lot of steps to get it to work but there was a lot of info out there on Google to help.  Not so with the 780 machines.  I do know that I have to upgrade my version of Symantec.
My machines have Intel Core 2 Quad 2.66GHz Q9400 processors and 4 GB Ram with 150 GB capacity.

Any help would be appreciated!

Hi,

Thank you for writing to us!

The support is not provide for the Optiplex 780 machines to windows 10 is because of various reasons.

1- System configuration

2- Compatibility issues

Moreover its not tested so we really wouldn't be able to tell you the issues that it may incur.

Thanks

Robin, with the 10s of thousands of 780 out there I am sure that I am not the only group that HAS to make this work.  Are you telling me that there is no way to make it work no matter what efforts I go to? I am hoping for some guidance from someone that has been successful and it was suggested that this would be a good forum to ask.

The OptiPlex 780 was released in Late 2009. Most would have been sold in 2009-2011 and with 4 years warranty standard, pretty much all units have expired warranty. Dell therefore are extremely unlikely to allocate resources to testing this model.

However the OptiPlex 780 is a robust Intel machine. Pretty much all the system drivers will be inbuilt into Windows 10 TH2 for it.

Make sure all systems are on Legacy BIOS revision A15:

This system doesn't have UEFI and SecureBoot.

Then made a Dell Backup and Recovery 16 GB USB flash Drive (using the latest version):

Then you can proceed with the clean install (recommended) or upgrade install (not recommended):

When making a Bootable USB use the MBR partition scheme for legacy BIOS.

Hi Philip,

I upgraded to Win 10 some years back but continue to have BSOD issues most likely due to a missing driver.

However, searching for the driver proves futile. I would be interested in your support or that of others in locating the missing driver. It's a PCI one but have no idea other than that.

Many thanks
