There are a few things that might help. Try taking the spool off the reel and winding the line on with a drill. You will need to build a holder of some sort. I use a threaded machine screw, a t-nut, and rubber washers to hold the spool. You just put the screw through the center hole of the spool and screw it into the Tnut, using the rubber washer to protect the spool from scarring and to keep it snugged up.
You can also take the spool in to a shop and have them do it, but a lot of the places have snot-nosed young'uns working, so make sure if you do that they know what they are doing.
There are two issues you are fighting with spinning reels. One is twist, and one is memory. Twist is unique to spinning gear, levelwind reels don't have it. Spooling line off the bulk spool and onto the reel spool like an old ree-to-reel tape machine helps the twist issue, but you still have to deal with memory. I would absolutely not recommend boiling your line. Spool it on nice and tight and let it sit overnight, that should help a lot. The first time you use it it will get wet, stretch a little bit, and will "remember" the new spool. Just know that line twist and memory are part of the program with spinning tackle if you use nylon or fluorocarbon. Superline is made from dyneema or polyethylene, and has its own set of particulars. A different category of line, really.
Also... when you cast, most modern reels can be closed by hand. If you can flip the bail by hand (not by cranking the handle) then DO SO. Slamming the bail closed with the handle shortens the lifespan of the reel, and causes headaches with the line. You will form a loop fairly often closing the bail with the handle, and this will cause a big wad of tangled, twisted line to fly off the reel when you cast the next time.
Cast, catch the line again against the spool with your fingertip or catch it in the crook of your index finger, and close the bail with your off hand, guiding the line to the roller in the bail as you do so. You will experience at an absolute minimum a 50% reduction in line management problems.
Lastly, there are a few good line treatments you can purchase. Reel Magic is a well know example. They make line slicker and softer, which increases casting and manageability. Change line frequently and use conditioners, observe good line management practices, and spinning reels can be a lot nicer to fish with.
