So im getting really stressed out at the minute, Im new to MBP's And i have a mid 2010 model with 8gb Ram and a 2.4ghz Intel I5, It was being really slow so i tried to do a factory reset which didnt work i formatted my HDD then when i click on Reinstall Mac Os X Mavericks i get the error Could not find installation information for this machine, So i tried to do an internet restore the one were you click Command-Option-R But when i enter my passcode for my wifi the box moves side to side which im guessing means incorrect passcode even though it was right, have also tried to boot from usb with a mavericks installer on it but i just get a circle with a line through it, What can i do? and could someone tell me how i could make a bootable usb with Os X On it using a windows computer as that is all i have to use now?
