Ubuntu 20.04 is installed on /dev/sda, on a SSD drive. All worked OK.

On /dev/sdc2 Windows10 was installed successfully. Both OS's are UEFI.

grub was not loaded on boot, so to boot Ubuntu or Windows10, was able after boot drive was changed in BIOS setup.

To try to fix it, following this guide.

After installing boot-repair which seemed to be successful, I got an error saying that /boot/grub/i386-pc/normal.mod not found and from now on, boot process stopped and stayed in grub Rescue mode.

The only thing I can do is to change boot drive to Windows10 Bootmanager at BIOS, which loads Windows10 OK.

How can it be fixed?

Windows does not recocnize EXT4 partitions, on which Ubuntu is installed. The ideal way to dualboot Windows and Ubuntu is to install Windows first, then Ubuntu will give you the option to install alongside Windows.

It shouldn't install grub for the i386-pc platform in UEFI systems (It should be x86_64-efi). If you are 100% sure you booted the installation in UEFI mode, did you select to mount the EFI partition? If not, that could be the reason.
