I am comparatively new to Ubuntu.I have a laptop with Windows10 installed on a 1TB SATA SSD.Today,i added another 240GB NVMe SSD & Installed Ubuntu 22.04 LTS.I can successfully dual boot & change the OS from BIOS.But unlike my Desktop(Where I have Ubuntu & Win7 on two different partitions of a same drive) where the GRUB appears & ask for the Ubuntu & Windows boot manager!When installing Ubuntu on the NVMe,i totally disconnected the Windows drive to play safe.Somewhere I read that OS-Prober will automatically detect the OS & shows on the GRUB but it's not happening!What should i do to get the dual boot menu on the GRUB?
Thanks in advance!!
