This shows the system is UEFI. How were both OSes installed? They need to be in the same mode. If your Windows is preinstalled then it certainly is in UEFI mode. Ubuntu must then be installed in the same mode.

Can you boot Windows directly? Open UEFI settings > Boot and select "Windows bootloader manager" as the frist option. Please report beack, we troubleshoot from there.

Yes after putting windows on top i am directly able to load windows without grub pooping up.

Here are some settings that i changed which might help you get an insight:
- for grub to open i had to changed the SATA operation mode from Raid to AHCI
- now i was able to start grub and boot ubuntu but whenever i clicked windows in the grub bootloader i found a Stop Code: INACCESSIBLE BOOT DEVICE error message
- after being unable to boot windows i changed it back to raid which helped me regain windows but now i am unable to access ubuntu as grub loader doesn't start

You need to install AHCI support in Windows then change the mode to AHCI.
Only then the dual-boot will work.

There are literally thousands of threads about the same thing.
