How do I install windows 10 on a device without USB boot?

[mithrilling]

before people ask irrelevant questions yes i am sure i cannot install it from a USB i cannot and will not install it from a USB. thank you

so... the iso created with media creation tool is too large for a DVD. I'm wondering if there's some other way to install windows 10 on this PC. Is it possible to install windows 8 and upgrade  it to 10? is there maybe some stripped drown version of windows 10?

Microsoft already ended upgrading from Windows 8 to 10. You can upgrade Windows 8 to Windows 10 version 1607, but you can't pass online verification so you have to use outdated 1607 offline.

I burned my ISO onto a Blu-Ray (BD-R) disc.  My desktop has had a LightScribe Blu-Ray burner for a long time.  I recently replaced the DVD drive in my laptop with a Blu-Ray drive.

Try to create a smaller ISO WITHOUT updates, and if you want them so much, install them later..

i ended up installing windows 8 and upgrading to 10 from the setup software from a usb made with media creation tool. its not activated but it's good enough
