HTC EVO Design 4G Won't Boot Into Recovery

I am an AC noob and not really sure if I'm doing this right but I have successfully rooted my Design 4G and cannot for the life of me, get my phone to boot into recovery. Every time I try I am given an error symbol and my phone reboots after 5-10 minutes. If anyone knows how to resolve this issue, please Please PLEASE lend your help.

Thanks so much,
Cliftone.

What was your rooting process ? Did you install a recovery
