Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

This seems to be somewhat different than similar questions I've looked through. I'm not really a programmer, and this is my first go at using any Linux build, so I've got no clue how to troubleshoot.

I just built a new desktop, with an Intel i7-3770K core (3.50GHz, 8MB cache, LGA1155), 120Gb SSD (intended for OS and programs), 1Tb hard drive.

I used the Pen Drive USB Installer and an 8Gb brand new USB stick to create my bootable USB stick to install Ubuntu 12.10. When I start the computer, it goes to the USB just fine, I get a screen that's purple and blank except for an image at the bottom that has a keyboard, "=", then a person in a circle. Then it goes to a string of code, with the last couple of lines:

[33.844918] ata8.00: exception Emask 0x52 SAct 0x0 SErr 0xffffffff action 0xe frozen
[33.844950] ata8: SError: { RecovData RecovComm UnrecovData Persist Proto HostInt PHYRdyChg PHYInt CommWake 10B8B Dispar BadCRC Handshk LinkSeq TrStaTrns UnrecFIS DevExch }
[33.845003] ata8.00: failed command: IDENTIFY PACKET DEVICE
[33.845021] ata8.00: cmd a1/00:01:00:00:00/00:00:00:00:00/00 tag 0 pio 512 in
[33.845021]          res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x56 (ATA bus error)
[33.845060] ata8.00: status: {DRDY}
[33.845073] ata8: hard resetting link

I can provide any other information that would make this make sense. :)

Edit: I tried this with 12.04 also, with the same error. The line just before this block is:

[4.679684] sd 8:0:0:0: [sdc] Attached SCSI removable disk

I started unplugging things that weren't the SSD (ie, the 1Tb drive and the blue-ray) and the blue-ray seems to be the problem, but I don't understand why it caused an error. It's not even on the boot-list.
