Dell Latitude e7470 is restarting into Recovery options after Installing 100% Big Sur by clover method.

Hi,

I tried to install Big Sur on my Dell Latitude e7470 with Opencore(Not clover) following this method - https://youtu.be/XAHSkwbIb7k

I am trying to install dual boot on only 1 ssd (as I don't have expansion slot)

While formatting ssd volume - I've selected Extended Journaled, not APFS as I am getting error while selecting APFS volume "You macOS firmware needs to be updated, select Extended journaled volume instead" - https://www.flickr.com/gp/21429760@N02/797cz7

After it finished 100% install, my laptop boots and after selecting Install macOS option from boot menu it again restarts directly into recovery. By clicking apple logo - startup disk - it shows only windows 10 drive.

here is my video I shot of the issue i am facing - https://youtu.be/H8STPDDnEn0

I have used e7470 EFI shared by someone on github/ reddit.

Any help would be appreciated.

my specs- Dell latitude e7470 - Intel i5 6300u- 16gb ram - 256 gb M.2 ssd already windows 10 installed
