You have to change a minor piece of your code, that is replace 'until' with 'while' ;-).

Just like so.. 
do
{
print "Enter Yes or No \n";
chomp($input = <>);
if ($input eq 'yes')
{
    print "Yes entered for system.\n";


}
elsif($input eq 'no')
{
    print "No entered for system.\n";

}

}
while ($input =~ /^yes$/ or $input =~ /^no$/);
