Gateway 7324GZ notenook, 2.8 P4 with window xp pro. Previously, it usually reboots itself unexpectly, so i decided to reinstall the windows xp pro. During the beginning of the reinstalling, it kept giving me "NTLDR is missing" error message. I was able to bypass that problem by reboot and retry several times. Finally I was able to start reformat and reinstall the OS. But, once it finished the step called "installing devices", the computer reboots itself and restarting to "installing devices". And, this step is just keep looping. Any suggestion?
