Yes it's true, and its here in a few days. I understand it downloadsusing the Windows Update route if you have clicked yes to the upgrade icon.
I think you will get a choice as to when to upgrade, but MS say no dual boot

"Can I dual boot the free upgrade of Windows 10 with my previous version of the operating system?

No. Upgrading to Windows 10 doesn't free up your previous license, so you cannot install your previous version on another machine or in a dual-boot configuration. The upgrade requires installing Windows 10 on top of a valid version of Windows 7 or Windows 8 installation to continue with the upgrade process.


This means you may be up the Swanney river, if your drivers don't work

Be careful...
