I ahve MSI u210 light, i want to know why is now takes long during booting... i ahve already formatted it but still the same.

Here are a few non-hardware-specific suggestions that have worked for me, not in any certain order, but I'd update the BIOS and try the first suggestion:

Unplug all of your peripherals, everything on the board (except HDD and RAM of course), and see if it boots faster. Only leave one stick of RAM in (primary slot), replace it with another stick each boot. If boots faster, replace everything one at a time, booting after each, until you find the problem device.

Try another HDD, make sure it's on the right SATA channel in the BIOS. Or even better, boot from a USB stick with DSL, Puppy Linux or Ubuntu (or whatever flavor you like). Watch the terminal on boot, see if it hangs on a certain device -this works in safe mode too.

Check your BIOS, make sure everything is legit, if it has a "fast boot" select it. May as well update the BIOS too, that may fix everything. You've probably done that though.

Poke it with a stick.
