I was using Windows 7 and Ubuntu 17.10, but got curious and decided to try Fedora 28... Now I can't boot to Windows 7 anymore.

Apparently the problem is that Windows 7 is in "legacy mode" and Fedora 28 installed itself in UEFI mode.

fdisk -l shows:

Partition 1 does not start on physical sector boundary.

How can I Force Anaconda to install Fedora 28 in Legacy Mode?
