I had one drive with Windows 8.1
, Ubuntu 15.10
and Ubuntu 14.04
. The windows was installed on different partition.
Then, I connect a SSD
drive and install Windows 10
and format the Windows 8.1
partition. I have a USB
with Ubuntu
installation.
Could anyone tell what should I do in order to get the grub menu back and be able to choose which operating system to start?
