upgrading ubuntu 32-bit to 64-bit

Asked by Jared

Hi, I'm an Ubuntu newbie, I just set up a dual-boot with vista and 32-bit ubuntu 10.04. I didn't realize it was a 32-bit. how can I upgrade to 64-bit 10.04? I have the iso already burned, if I leave my system as is and began the installation process for the 64-bit Ubuntu, would the installer be able to replace the 32 or do I need to uninstall the 32, if so how can I import my downloads and all that good stuff??? Any tips or advice would be appreciated.

To change architecture you will need to reinstall. There is no other way. Simply wipe clean, reinstall then restore your user data from backup. The need to restore user data is removed if you have a separate home partition (not default in Ubuntu). The app config files are all stored as hidden folders in $HOME so will need backing up to retain their settings.

If you boot to windows and use the disk management app you can delete the partitions, When you boot to livecd again to install you will have unpartitioned space you can now install to.

If you used wubi then you can use add/remove programs in windows and then reinstall using an MD5 tested ISO file or a burned CD from an MD5 tested ISO.
