When I am downloading Ubuntu to burn it and install on a partition, I keep getting the amd version (ubuntu-12.04.2-desktop-amd64.iso). I don't have an amd processor but I have intel i7 3740QM.

On the download page I just see one link that's interesting (12.04 since it's stable), no option for intel processors. Should I still use this file?

I found another ISO file earlier but I'm not sure from there. It's filename is ubuntu-12.04.2-desktop-i386.iso and I burned a CD from it. The reason I think it may be wrong is that when I'm booting from it I get the following message:

ata_id[334]: HDIO_GET_IDENTITY failed for ´/dev/sdc´: Invalid argument

The boot stops there and I need to go reconfigure BIOS or eject the CD to boot again.

I figured there's something wrong with my CD so I'll burn another one so that's why I want to be sure I'm using the right ISO to burn.

In this questions there's someone getting the same or similar error message. Answers suggests that the message can be ignored - but I don't get further, that message is shown and the boot is not proceeding.

  • You can use the i386 iso on just about any PC. The amd64 iso is for 64-bit capable processors; not just The ones from AMD. Take a look at this question What is the difference between 32-bit and 64-bit and which should I choose? – Warren Hill May 4 '13 at 19:12
  • WarrenHill Thanks, I have burnt both now and as I boot from the CD I still get that error message (sometimes ata_id[333]). If that problem is because the OS can't find my disk drive, then how come it's trying to boot from it, as @thefourtheye suggests? – miphe May 18 '13 at 21:12

It is better to install a 64 bit version of Ubuntu, if your processor architecture supports it. amd64 iso corresponds to 64 bit version of Ubuntu.

And its called amd64 because, the original specifications for x86-64 was created by AMD. (Source: http://en.wikipedia.org/wiki/X86-64)

Your processor supports 64 bit instruction set. (Source : http://ark.intel.com/products/70847). So you can use amd64 iso.

And this error

ata_id[334]: HDIO_GET_IDENTITY failed for ´/dev/sdc´: Invalid argument

is most likely because of the OS unable to identify your Disk Drive. For more information about it, read this question Ubuntu not booting from CD or USB, how can I make sure OS finds my drive?
