18.04 dual boot showing grub2 manual

Did a fresh install of 18.04 alongside Windows 10 (UEFI). Now my system boots only into grub2 commandline.

I am able to boot into both windows by executing

> chainloader (hd0,gpt1)/efi/Microsoft/bootmfgw.efi

and ubuntu by executing

> set prefix=(hd0,gpt6)/boot/grub

> set root=(hd0,gpt6)

> insmod linux

> insmod normal

> normal

I ran grub-install, boot repair several times after booting into ubuntu, but to no effect.
I still keep booting into grub commandline.

Any help is appreciated.

Edit -
** tried these and did not work**:

• grub-install with grub-efi-amd4




• grub install from live usb




• boot-repair from live usb or ubuntu




• fresh install of 18.04 again lands in grub manual
