i have a lenovo s10e netbook so obviously i cant use a recovery disk to fix this mess. a couple days ago i was transferring some files from this thing to my external hard drive and since then ive lost a lot of abilities that are normally basic. i cant use defrag or install any new applications at all. on top of that i cant even move any files anywhere on my the hard drive or even to the external drive. what could i have done to cause this problem and how do i go about fixing it?
