So I just installed Ubuntu 10.10 via Wubi over Win XP Pro 32bit, my processor is X64, and I have 4GB of RAM installed, the Ubuntu installs as 64bit but it only shows 2.9 GiB of RAM even tho the OS is 64bit, why is this? The whole reason i did this was because with windows xp you cannot use a 32bit license for 64bit version, unlike Vista/7 which works as long as version is same (pro ultim etc) and I need 64bit, but its only reading 2.9 :S?

My OS is Linux ubuntu 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux.

Are you sure you installed the 64bit version? What does uname -a say? – psusi Jan 9 '12 at 19:48
What BIOS (and which version) do you have? Sometimes there are problems with older versions: – qbi Apr 9 '12 at 12:47
