I’m currently pulling out hairs about a problem with my wife’s new Samsung Book 9 laptop. It comes preinstalled with Windows 8. She wants Windows 7 Pro. I’ve board a Windows 7 Pro 64-bit for her and thought that this would be just like a regular “clean Windows installation” but unfortunately that has not been the case. From Samsung’s website I followed some instructions on how to configure the BIOS to be able to function with Windows 7. That meant to change the BIOS specification from UEFI to CSM.

How to Jail Break UEFI to RUN Ubuntu? Up vote-2 down vote favorite. Linux, Ubuntu, not even Windows 8.1, 8, 7, Vista, XP or any flavor of Windows will run.

I disabled the Fast Boot config so it would recognize my portable DVD-drive and changed the Boot-sequence. I also disabled the Secure Boot configuration. Everything worked and I could boot from the Windows 7 dvd and begin the installation process. But the problem came when going into the section where one can choose partitions for the installation, delete, format and create new. I deleted the Windows 8 partition and created a new but I got an error at the bottom of the screening telling me that I could not install on this partition. When going into Details on that message it stated that it could not be installed because it was running on GPT partition and not NTFS.
