GRUB not loading after installing OpenSuse TumbleWeed

Question

Recently I decided to switch from Ubuntu to OpenSuse so normally I attained the TumbleWeed image from OpenSuse and began installing it.

The installation process finished without any problem but after I rebooted to enter my newly installed distro I encountered a blank black screen. (GRUB is not loaded)

After much inquiring I managed to boot into Gnome using the installation disk's Boot installed system feature but whenever I reboot the same thing happens.

I tried re-installing GRUB using this guide but it did not work.

Since I had my /home and /opt on separate partitions than / I skipped formatting them and just formatted the root partition.

Here is what fdisk -l spurts out:

As you can see I have 2 HDDs (my primary being an SSD disk).

Upon installation I used the following partition table:

/dev/sda1 mounted on /
/dev/sda2 mounted on /opt
/dev/sda3 mounted on /home
/dev/sda4 (fat) mounted on /boot/efi
/dev/sda5 mounted on swap
/dev/sda6 unpartitioned

So here I am stuck at that black screen. I tried to be as much detailed as possible so if anyone could help me I'd be immensely grateful.

I finally managed to fix the issue and here are the steps I took in case someone else faced the same problem.

First you need to boot into your installation by either using Installation Disk or using the live version. It's done by entering the installation section of installer and then clicking Abort and then inside the blue screen following the Installation --> Boot installed system to get into your system.

After that you need to open up Settings and then going into Yast setting page. Finally by clicking Boot Loader you can install GRUB2 on to your MBR.

After that the GRUB screen will load.

I faced another issue which upon selecting OpenSuse in grub there were 2 errors indicating that linuxefi and initrdefi command can not be found.

It is fixed by booting in Rescue Mode and and mounting your root partition and editing /boot/grub2/grub.cfg and replacing every instance of linuxefi and initrdefi by their non efi equivalent which respectively are linux and initrd.
