try starting the laptop and pressing alt + f10 to get to acer recovery
actually my friend has an Emachine 642 not an acer-tried pressing alt and f10 but the recovery management wont work-the laptop continues to reboot but wont begin Windows-wont start in Safe mode either-my friend was told that she needed a recovery disk-is that the only way her laptop will start up and i assume now it has to be Recovery Disk from another Emachines running Win 7-am I correct???????
