Hi All, I currently have an Acer Aspire One Model ZG5 (8.9") with Windows XP Home. I recently tried the Alt+F10 recovery because it was not working properly and I wanted to get it back to factory default settings. It made it through the recovery process, but unfortunately not all the way! After the Windows screen appears at the beginning that allows you to select boot options it goes to an all blue screen that says, STOP: c000021a (Fatal System Error) and continues to try and restart itself with no luck. I do not have a boot CD. I do however have a brand new Aspire One that a family member recently purchased that also has Windows XP Home edition. How can I get my model working properly? I'm somewhat of a noob when it comes to this, but I'm hoping there might be a way to create a bootable USB drive off the new Aspire One and use it on the busted one? Any help is greatly appreciated! Thanks!
