  • What's your processor? – LakshyaAg Feb 12 '15 at 9:19

  • Intel® Core™2 Duo Processor E6300 (2M Cache, 1.86 GHz, 1066 MHz FSB) specifications -> Instruction Set = 64-bit. 64-bit operating system is compatible with your hardware and recommended for your hardware. The CPU is a bit slow, so its a toss-up between either Ubuntu or Xubuntu, and I would choose Ubuntu. – karel Feb 12 '15 at 10:11

There is no cross-effect with dual-boot, where the other OS is 32-bit.

Generally you should use 64-bit if you have at least 2GB RAM, and your PC/laptop is reasonably modern. Ubuntu 64-bit includes full 32-bit support.

Possible exceptions would be: need to support UEFI (avoid 32-bit), or (laptop with) Intel Atom graphics (needs 32-bit driver).


First check your CPU instructions.If it has 64 bit instructions, then you can run any 32 or 64-bit systems as far as I know.

Dell Optiplex 745 will probably run 64-bit Ubuntu just fine.

  1. It uses a 64-bit capable processor .

  2. There are examples on web where people have installed and run 64-bit OS on the system successfully .
