My tablet did an update now it won't boot into windows I've tried alt+f10 to do a system recovery and it won't even go into recovery the screen just blinks than reboots i know there's a way to get into erecovery when it's booting up I just can't seem to figure out what buttons to push to get it into recovery mode I called Acer and they want to charge me $100 to tell me how to do this! Help I need my tablet i know i may lose everything on the hard drive at this point I'm okay with that i just need my system back
