I have tried to format my Acer Aspire One 722 laptop. Windows 7 Ultimate was installed perfectly, but problems started when I tried to reboot the computer. The computer starts with the Acer eRecovery Management (V8.3.2). When Windows was unable to start up I tried the option RESTORE OPERATING SYSTEM AND RETAIN USER DATA in the Acer eRecovery Management. The process completed successfully, but still the laptop starts with Acer eRecovery Management with same options. Please help me to solve this problem
That sounds like a hard disk problem. Get the disk out of the laptop and connect it to a pc for error checking, if you have the chance. Booting from a linux live CD is another option. Or rma it, if it's still under warranty.
