Bowyer impressed during two spells as caretaker manager at Ewood Park last season, guiding an embattled squad away from the danger of a second successive relegation following Michael Appleton's surprise sacking.
Having agreed a 12-month rolling contract, Bowyer will meet the media for the first time as full-time boss on Tuesday and Singh has handed him an endorsement of sorts after a season where Steve Kean, Henning Berg and Appleton all failed to make the grade in the Rovers hotseat.
He told the Lancashire Telegraph: "The big challenge is to now not encourage mediocrity. In my opinion, Gary has the support of the majority at the club unlike previous managers, who were pretty much clueless.
"The advantage that Gary has is from his two different stints being in charge he would certainly be aware that he had a very good squad that played with creativity and joy first time out.
"His second stint, which went through till the end of the season, had him dealing with a decimated, average squad. I trust Gary will also not alienate players as previous managers did."
