redhat enterprise linux dual boot installation withwindows 8.1

Hello all,
Several time trying to install rhel 7.5 as dual boot with windows 8.1 64 bit
But every time I get this screen on the boot screen
" windows recovery Environment (Loader) (on /dev/sda2) " and windows boot gets corrupted
Rhel works properly after installation but windows boot damaged
I followed the instructions from youtube video but still get same error,
Someone has advise?

Best regards
Hammam
