my acer aspire r11 was interupted during update then when restarting it just keeps restarting and nothing happens just restarting all the time , when tried alt+f10 it worked but all choices failed, I don't have a backup or recovery CD cause am offshore, so any advice I can do

You say 'update', but was it just an 'update' or was it during an 'upgrade' of windows?
