Dualboot: Fix Fedora23 legacy install on PC with Windows8 UEFI

Hello! I have an HP laptop that came with Windows 8 64-bit with the UEFI option. Recently I made a disk partition using the w8 utility and proceeded to install Fedora23 from an USB using the live image. I didn-t read the guides carefully, and since my USB wasn-t recognized on startup, I enabled Legacy Mode and installed Fedora23.

Now, at startup I get 2 options, Fedora and Windows, but Windows throws an error about Boot\BCD: "The boot configuration data for your PC is missing or contains error". I have tried fixing it but to no avail Fedora runs and I can access all the files of the w8 partition from it.

I know my mistake was to install Fedora on legacy mode while w8 was on UEFI (I just read with full attention the documentation ). I-m currently downloading the 64bit live image and I-m going to create a Live USB (using the linux terminal) enabled for EFI. I have the following question

  1. Is there a way to erase my Fedora legacy/BIOSinstallation in order to make the Fedora UEFI installation?

Thank you for your attention

Solved it. Just reinstalled Fedora23 using the liveUSB correctly formatted in UEFI.

On the installation menu, when you have to select the destination disks, I chose 'Reclaim Space' and deleted my wrong Fedora Installation and a BIOS partition (1MB in size).

Got Windows running again.

Lesson: Read carefully the documentation

Sorry for the trouble
