Machine keeps saying "disk ERROR " even on new bought DVD's???

You have to go into your BIOS and select booting from Disk not hard drive when i say disk i mean either the cdrom or dvd disk players attached to your motherboard. also you can get a boot disk to try that at the link below.

i did everyting today to fix this. bought new dvds, name brands different, tried finding codes, called the number. trust me. try this. clean it. thats All i did. cleaned it with a dvd cd cleaning disc, the one with two little brushes on it, nothing special, ran it until i heard the beep, popped my dvd in, they all worked. everyone, im still recording. i ran it about four times. now, if you tried to burn a dvd, and got the error, throw that dvd away. because i tried about ten dvds. after i fixed it, THOSE dvds were no longer usable. dont know why. hope this works.

If it does it with a shop bought dvd then there is a strong chance that there is a fault on the unit.

If however you are using home made dvd's cd's'then that is a different situation and you should double check your source burning capabilities.

Hello there
you will need to check the way the device reads the disk if may have changed if you tried using a ordinary dvd then went a dvd/r some times you need to change the settings back to the way it was when you installed it ok

I figured how to get the Memorex DVD-R's working again. I went and bought a DVD lens cleaner and all the errors stopped at least for a while I hope.

More than likely the DVD drive in your unit is bad.

Is you new hard drive lager than you old on and was the disk drive a factory replacement cause with those disks if you even change just that they will not work
