Welcome to the Community,
I hope it's ok to answer in English.
In order to be able to run 64-bit guests, your physical system needs a 64-bit CPU with - assuming it has an Intel CPU - support for Intel Virtualization Technology (VT-x). This has to be enabled in your system's BIOS. After changing this setting and saving the BIOS settings you need to power cycle (power off/power on) the system.

Como disse nosso amigo, o lance é só habilitar o VT na BIOS. Algumas não tem suporte a isso, e talvez voce precise atualizar a BIOS do teu computador para suportar este feature.
Se tiver dúvida dá um toque aí pra gente.
Thanks my friends for reply me,
I updated the bios to latest version and did not gave me the option of VT.
There's another way to configure?
My versiona the BIOS is Insyde f.67.
Unfortunately not. What type/model of CPU do you have in the system?
André
hello,
My sistem is Intel core 2 Duo T6600, in website of HP a have information speaking this CPU not suported VT.
Unfortunately that's correct (see http://ark.intel.com/products/37255/Intel-Core2-Duo-Processor-T6600-%282M-Cache-2_20-GHz-800-MHz-FSB...) and there's no workaround to run 64-bit guests. Sorry,
André
