Problem installing amdx64 64-Bit Jaunty

[iKevin09]

The x84 32-bit Jaunty installs fine, but when I try to delete the partition and install the 64-bit Jaunty, installation states that either my optical drive is shot, or my hard drive is shot and the installation cannot continue. So I reverted back to 32-bit to see if it was actually the problem, and 32-bit installed perfectly fine..

Anybody know what the problem is? Should I burn another 64-bit CD?

I'm running 4GB of DDR2 RAM, Intel Core 2 Duo/Centrino2 that is 64-bit compatable. Running nVidia Quadro 770m 512MB workstation graphics as well..

Any help would be greatly appreciated.

Did you run 'Check CD for defects' on the 64-bit LiveCD?

if it checks out ok after Ann's suggestion check the iso you downloaded - MD5SUM (https://help.ubuntu.com/community/HowToMD5SUM)

If that checks out try burning the image to Cd at a slow speed such as 4x.

I have done the Check CD for Integrity or whatever it checks for. It passes. I'll try to re-install again. My laptop was running at like 104F but I don't think that was too hot.

Okay, well I tried re-installing it. Didn't work. I'm redownloading it right now. I don't have the iso image of the original 64-bit Jaunty anymore. I'm going to use that MD5SUM program on the iso to see if it checks.

[iKevin09]

The sums are different from what the iso says and what it should be from the UbuntuHashes.

Then your iso is corrupted. They should match exactly! Try downloading from a bittorrent link or a different download location.
