so i recently have built a build and i am haveing start up erros. it says its unknowen and an error comes up when it does the startup recovery. So i am split to rather try to renstall windows or restor to default. So i troented windows 7 since i couldnt find my old box and i set boot priority to my cd drive but nothing has changed. i am getting a quik blue flashing screen every once in a while. If it booted the disk i could install windows. i have put the windows on the disk like a usb and burned it also.
You can recover important data by installing Ubuntu side by side to your errorneous Windows then copy between Ubuntu and Windows to an externel drive. Then I reccommend getting a blank DVD, get that Windows ISO you have, then use this: http://www.freeisoburner.com/ to burn it. Then format your entire drive and reinstall Windows.
