I have a problem, my sister bought an Acer laptop. you know those ulta small laptops with no built in cd/dvd drive. she have a windows error and upon every boot when windows starts, a BSOD will appear and restarts or turns off the computer. I know how to fix that, I plugged in the external dvd/cd drive and in it is a windows xp cd, when I boot the computer I press f12 for boot option menu and select the external dvd drive. The problem is it didn't read the external drive and begins the BSOD windows error like before.
