How to force 32-bit installation via WUBI

This note relates to WUBI for Ubuntu 10.04.

Reference: Can I force Wubi to download and install a 32 bit version of Ubuntu?

On machines that feature a 64-bit processor and not much memory (less than 1GB), it might be beneficial to install a 32-bit version of Ubuntu as opposed to a 64-bit version. This reason is that the performance price in processing is probably less than the performance price in swapping due to restricted memory. 64-bit versions of kernels and applications tend to use more memory than their 32-bit counterparts.

WUBI detects the computer configuration and selects the most appropriate version of Ubuntu. On a machine equipped with a 64-bit processor, it generally elects to use a 64-bit version of Ubuntu.

To force WUBI to use a 32-bit version of Ubuntu, use the “–32bit” command line option. Instead of starting WUBI via its icon, open a command-line prompt and run:

wubi --32bit

Continue the remainder of the installation as usual.

  1. This can be done also by just creating a shortcut to Wubi and adding –32bit to the Target in properties
