Checksums are used to verify that the file/ application/ etc has not been tampered with from point A to point B, they are security measures.

You either have a bad disc or downloaded an iso from an unreliable source.

If you have a disc, download an iso from a reliable source and use the product key on the cd packaging for the install.

If you used an iso, download another iso from a better source.

I would try another source too. I agree with pioneer.

BTW pioneer, I used to swear buy pioneer the had the very best head units and infinity kappas not sure anymore. I also used to swear by pioneer surround receivers. now I use a stock radio and an onkyo receiver. getting old lol

Thanks that was the problem I got a new disc but now it tells me i have a I/O error because a USB device or storage was removed/failing while trying to install but ive unplugged everything un necessary and retried but i get the same thing. I really hope my new SSD isnt failing like what it suggest

Make sure the power and SATA cables are plugged in correctly.
