"And hopefully we can be the ones to take them back to where everyone wants to be."
Grayson, who has only been out of a job since he was
dismissed by Huddersfield
on 24 January, will have former assistant Glynn Snodin in his coaching set-up.
"I'm a football person and I love working," continued Grayson. "I had a holiday last week but I was starting to get itchy feet already.
"I love working, I love football and when I spoke to a few people about if I had an opportunity to go back into the game quickly they said 'take it', because you can be out of work a long time.
"It wasn't so long ago that this football club was in the play-off positions for the Premiership, never mind to get into the Championship.
"We want to come into the football club and try to recreate that positive place, the passion among the supporters and the performances from the players which will gather the spirit of what Preston North End is all about."
John Dreyer, who had been in caretaker charge, will also remain at Deepdale.
