Re: Cannot boot Windows 8 after unsuccessful install
LInux partition would not make any difference to Windows booting. Windows does not know it exists.
But two efi partitions definitely confused system. It has to know which partition to find boot files. And it looks like the Windows boot files are still in the 'real' efi partition.
The only other issue may be how did you resize Windows? Always best to use Windows to shrink Windows and immediately reboot as it wants to run chkdsk or other repairs on the NTFS partition. So chkdsk may also be required if still having boot issues with Windows.
