That was an example of my file.. My file does not have any numbers. So i need to select it from the existence of Particular Character, For Example,

Event ID =1
.
.
.
.
EventID=25
.
.
.
.
EventID=50

I need to select from "EventID=25" to rest of the file.

Depends, the OP asked "Select from EventID=25 to the end", now it depends on how you interpret select. I personally think select means display. Plus if you use d with "sed -n" nothing will get printed.
