I was using Ubuntu 22.04 along with Windows 10 dual boot style. However today I upgraded from 22.04 to 24.04.1 from whatever menu link it provided. 24.04.1 came up well ... however I can no more access Windows. When I power on the system it no more gives me a choice to choose between Windows or Ubuntu... like it used to do.
Any guidance on how to recover from this situation?Thanks in advance.
