Windows are to be closed and locked before the crew begins take-off, but if the window comes open, Boeing training procedures are to continue the take-off.
There is nothing mechanically wrong with the airplane, and its more dangerous to abort a take-off at high speed than it is to leave a cockpit window open. Once the crew is airborne, they can divert their attention to the window. The nose deflects air around the side windscreens, so other than some noise, they are able to function just fine.

at which altitude they could close the window at the earliest do you think?
I have known guys to fly big jets from MIA to FLL with the cockpit windows open, surprisingly enough, the air just rushes around the windows and doesn't actually blow you away getting inside, so it will be alot louder but as far as danger is concerned, very little, obviously the aircraft will not pressurize, but once airborne they can close the window quite easily.

I have no idea of a specific FL, but they would likely take care of the window ASAP once they have taken off.
There's a video showing a clip from a Boeing training video where the exact scenario above takes place. I searched for it on YouTube, but the only clips I could find were dubbed over with Regge music and lame comments in Spanish or Portuguese

I'd think that once they reduce from takeoff power to climb power, one pilot would fly and the other would shut the window. That's generally at about 1000' to 1500' AGL, but can very by airport and airline.

Does that cause a significant pressure problem compared to taking off unpressurized? Is the plane fully pressurized at the end of the takeoff roll?

I'd imagine it would be similar to having an outflow valve stuck open, so the plane wouldn't be able to pressurize until it was closed, but other than that it shouldn't be a big problem, considering that as long as they got it closed before 7000', the cabin altitude would still be climbing after that point. Though the longer they left it open the more ear-popping there would be in the back.

It does get harder to close the faster the airplane goes but the positive differential pressure helps you close it. So as long as you begin to close it early, the increasing cabin pressure will actually help you close it. In testing it is actually not that hard to just turn the window crank and close it.

I would think the best time to close it would be right when the plane rotates, as that is the time when the most airflow is diverted from the windscreen.

That would actually be the worst time. If a window pops open there is no danger however the pilots need to fly the plane first, stabilize the situation and lastly close the window.

jetphotos.net has a couple of closeups. Interestingly enough, two different DE 753's took off with the window open on the same day. The captions say that they are training flights, perhaps it was part of the training. I would link to the photos, but...

The nose diverts air around the side windows no matter what. Even after the plane is airborne, surprisingly little wind is felt inside the cockpit.
Granted, it's noisy as hell and the aircraft can't pressurize, but the crew isn't subject to tornado force winds or anything.

the comment says, it was a training flight. they do this to simulate crosswind take offs.

29 EMBQA: What makes you think it was full of passengers...?? I see empty seats
30 Legoguy: I think in the third picture, what you think are passengers, are actually just seats
31 Toolman: because there is a bigger resistance on one side of the plane.
32 Wingnut135: On most heavy aircraft the window is cranked open and closed, as well as on the 753. You can see the crank in this pic, just under the window, to the
33 2H4: An open window would not produce even a remotely accurate representation of a crosswind takeoff. 2H4
34 LarSPL: it is not illegal to fly with an open window. you just cant pressurize the aircraft. it does not reflect a crosswind takeoff. just to correct some com
35 DavidT: There is a Boeing training video availble on the net somewhere that discusses exactly this. It shows a takeoff with an open window on a 737,75/67, 747
36 FSPilot747: Actually, to simulate crosswind takeoffs, you find a windy day.
