I installed Unbuntu 12.04 LTS 64-bit on my Dell 8500-XPS. This was a side-by-side install with Windows 7 64-bit. My system has 16 gig RAM. When I check my Unbutu system settings - details, it says my OS type is 32-bit. What happened?

Output of uname -a: 3.11.0-18-generic #32~precise1-Ubuntu SMP Thu Feb 20 17:54:21 UTC 2014 i686 i686 i386 GNU/Linux

Output of uname -m: i686

could you paste the output of uname -a or uname -m? –  sagarchalise Mar 25 at 6:43

How did you infer you installed 64-bit Ubuntu? –  i08in Mar 28 at 3:51

From the output of uname -a, it was clearly shown that you had installed Ubuntu 32 bit.

3.11.0-18-generic #32~precise1-Ubuntu SMP Thu Feb 20 17:54:21 UTC 2014 i686 i686 i386 GNU/Linux

Yes, checking the install CD that is clear as well. I'm quite certain I selected the 64-bit version when I burned the CD. I will try again. –  user261815 Mar 28 at 3:53
    
Please open the files in that installation cd.If there is any EFI folder on that, it's sure that the cd contains 64 bit Ubuntu.If not, then it is 32 bit. –  Avinash Raj Mar 28 at 3:55
