That is all.

It might be helpful to list computer type AGE os etc.   Hi John6129,

Please try these steps:

If you have the original Windows Vista installation disc:

• Turn on the computer and INSERT the disc
• Restart the computer
• If prompted, press any key to start Windows from the installation disc.
• Choose your language settings, then click next
• Click "Repair your computer"
• SELECT your operating system then click next
• On the System Recovery Options menu, click STARTUP Repair. Startup Repair might prompt you to make choices as it tries to fix the problem, and if necessary, it might restart your computer as it makes repairs.

• Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
• Press and hold the F8 key as your computer starts before the windows logo appears
• On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press ENTER. (If Repair your computer is not listed as an option, then your computer does not include Startup Repair as a preinstalled recovery option.)
• Select a keyboard layout, and then click Next
• Select a user name and enter the password, and then click OK
• On the System Recovery Options menu, click Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem and, if necessary, it might restart your computer as it makes repairs.
