If you booted to Windows 2000 or Windows XP with the drives attached to the computer, a signature has been written to the boot partition which makes the drive unbootable. A utility called 'maketivobootable' will fix this.
If you did NOT boot to Windows, capture the serial output so we can see why it isn't booting.
ddrescue MAY be able to copy the drives if you can boot them.
There's a difference between needing help, and just being plain ole' lazy.
