I was looking at upgrading my 6 year old hard drive Western Digital Caviar SE WD1600JS 160GB 7200 RPM 8MB Cache SATA to a Western Digital VelociRaptor WD740HLFS 74GB 10000 RPM SATA 3.0Gb/s 3.5. So after the restore process using Norton Ghost 15 I now get a Master Boot Record Error Press any key. If I press the key the system boots and runs ok. The operating system is a 32 bit Windows XP Media Center Edition. Please help if possible.
