Ok so a few weeks ago my laptop just randomly stopped working. My mom sent her old one over because she just replaced it with an iPad. My old laptop is a Dell Inspiron 1521, It has Windows 7 Home premium, 32bit operating system, with a 320gb hard drive and the new laptop is a Dell Inspiron 1521 with Windows Vista Home Premium, and also a 32 bit system. I have tried when my old computer worked to preform a factory reset and it did not have a Dell Factory Image on the computer . I read some where that the hard drive would need reformated in order to work. Could someone give me some help like a step by step guide to make these work if they are compatable? I plugged the old hard drive into the new pc and it loads to the startup repair and shows the accounts i had on it before so i would imagine it works but i think i need to run start up repair? Some kind of instructions on how to swap these hard drives, even if i would have to re format all of the hard drives i would be ok with that
