[Bug 1573306] Re: Installation fails. I've got a custom partitioned GPT HDD

[Phillip Susi]

As I mentioned, there is a warning that mentions you already have
operating systems ( windows ) on this computer set up for bios boot, and
continuing in EFI mode may cause trouble, and suggesting switching back
to bios mode.
