What is the make / model of the acer?
also, on sticker on back, it reads: aspire one D150-1577
i'd be willing to do a formatting and reloading of windows xp (wasn't much on the laptop so don't mind starting over), but this doesn't have cd drive and i don't have a flash drive that would facilitiate booting and loading xp just yet.
Ok that's an AOD150.
You can restore the OS from the "hidden drive".
