Dual Boot RHEL 7.4 and Windows 10

I bought a new laptop. I wanted to dual boot Windows 10 and linux although it is unsupported. I installed CentOS 7 which worked but didn't allow me to boot into Windows 10. So I did a clean reinstall of Windows 10 then installed RHEL 7.4. The RHEL installation seemed to go well. I chose default to get automatic partitioning and entered other values as required. It seemed to install but upon boot I don't get a grub menu offering a choice of linux or win 10. I booted into the rescue environment and ran grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg. It shows 5 lines saying that it has found everything but still no grub menu upon reboot. I'm lost. Would a reinstall of RHEL work? Any help would be appreciated.
