Lost Xbox 360 data

I have had my 360 for a couple years now and just recently upgraded to an xbox live account. I created a brand new one using a gamertag that xbox live choose for me. After doing that, however, I found that any of the offline saved data from previous games was erased (NBA 2k14 and NCAA10). I have signed in to all the gamertags on my account and can't find it anywhere. Is there a way to recover this? Or am I just out of luck?

Unfortunately the achievements and save data in your other profiles can't be transferred to your new Live account. Like you, I found that out the hard way.
