    EFI Windows has the normal Windows partition that holds Windows and all your files, an EFI boot partition, and a recovery partition. Windows 10 upgraded from 8/8.1 has an additional EFI boot or recovery partition--I can't remember which, because the original partition created by 8 is too small for 10.

    I typically see 2 Windows entries at boot time. One will boot properly, I believe this is the EFI boot. The other will not, it leads to a black screen with white text telling me no bootable partition found. Occasionally I see a third entry, but it goes away. I'm not sure why that shows up from time to time but also goes away. I think it has to do with Windows updates, but that is pure speculation.

    I ended up installing rEFInd. It is WAY faster than holding ALT/OPTION at startup, and you can also hide any extraneous entries. I'm very happy with it and never going back.

    Thanks for reply I have checked and first Windows will not boot second boots to Windows 10 the third is Windows EFI and boots to Windows 10 so I would think the second one must be booted in bios but I would like to get rid of the first if possible.
