I invested in a start-up company that failed, losing my entire investment. I deducted that loss in 2012. How long to I need to keep the record of that failed investment?

Personally, I'd frame it and put it on the wall as a reminder not to do that again. (And yes, I have been there, done that.) But now that it's seven years later, you may feel better burning those records.

IRS says:

Keep records for 7 years if you file a claim for a loss from worthless securities or bad debt deduction.
