I got a new Seagate FireCuda 2.5' 2TBHDD. Going to try and swap between drives Windows7Pro on a the 1tb the drive that came with the machine and Windows10Pro that I'm going to install on the 2TB. Can I install Windows10 using legacy mode. If I can will it affect any thing in the OS for example will it still boot into Windows10 play and record using the DVD drive, still use USB. If I can't, when I swap the drive back to Windows7 will I be able to go from UEFI mode back to legacy mode.
