You may do that in the following steps:
Code:
1. head -1 File2.txt > result.tmp
2. grep 'record1' File1.txt >> result.tmp
3. awk 'NR>1' File2.txt > result.tmp
4. mv result.tmp File2.txt

Kinda cumbersome, but this is what comes to my head at the first sight of your question.
I know this can be achieved more elegantly with SED, but SED is still strange to me.
