I installed fedora 26 along side my windows 10. I updated the fedora to 27 and everything was working fine for more than 2 weeks. Then i realized that i had not installed drivers for my nvidia graphics card on fedora and to do that i used the rpmfusion link and installed the graphics card. When i rebooted my system it only now boots into the blue screen of SHIM UEFI MOK thing. I have tried adding the hash of all the .efi files but that doesn't work as well. I can boot into my windows but my fedora is blocked out. How can i get grub as my default boot-loader again. When i consulted the grub manual it says that i should not use grub2 on a efi system which has had me confused even more

Partition table entries are not in disk order.

My Linux is installed on NVMe Toshiba 256 GB (as 94 GB partition) SSD and Secure Boot is off and I have disabled the fast boot and hibernation on my windows

Please help me get back my system. I have been trying to do this and haven't had any luck with it

i had the same issue due to other reasons some weeks ago, but i wasn't able to fix it and did a complete reinstall. i think its more secure and faster than to try fixing... but i am not a linux wizard at all.

Are the nvidia drivers signed? Or do you need to boot in UEFI non-secure mode?

I followed this link: https://rpmfusion.org/Howto/NVIDIA#Cu... because i have a GTX 1060 Max Q in my system I didnot need to turn off the secure-boot before. I did it only when grub was no longer the default boot-loader

You said:

system which has had me confused even more.

This I am pretty sure is very old information, and is no longer true. Where did you find that manual?
