The computer is having trouble finding the boot user. Have you tried booting to your operating system disk? If you can boot to the OS goto utilities/disk repair and run disk repair until it reports no trouble found. If successful you should do a complete backup of your data as this could be a indicator of your hard drive going bad. I am including a link to a problem like yours for reference. Ralph
