Installing 64 bit Ubuntu over 32 bit


Hey guys

I just downloaded Ubuntu remix Netbook edition 10.10. during the installation i wasnt paying attention and I downloaded the 32 bit version... The thing is the Unity interface is not showing up, and perhaps its becuase of this 32 bit thing.
Anyway I would like to install the 64 bit version, not . Ive read around that the best way is to uninstall everything from windows (its dual boot) and re install. The problem is I dont have a windows xp start up cd, so that wouldnt work, or would be complicated. However somewhere I read I could install over it, and I would like your thoughts. First off how would that work?? Ive learned my lesson not to play with the OS...

So I guess it all comes down to how to delete Ubuntu, without a Windows xp CD. To make it harder I dont know anything of computers so yay!

If you want the 64 bit version, you will have to download it. There may be a way to upgrade the 32 bit version to 64 after you install the 32 bit version, but I'm not aware of it.

If you don't care to save anything, just install the Ubuntu remix Netbook edition just as if you were installing to a fresh hard drive. The install process should write over anything that was previously on the hard drive. You won't have to uninstall anything in this case.

The same goes for keeping a dual boot system. I will assume you did the dual boot setup yourself. Just install the new Ubuntu over the non-Windows partitions. There is no need to uninstall/remove the stuff on the non-Windows partitions. They will get written over.

If you want to add the new Ubuntu as a third boot option, you will need to learn more about hard drive partitions. You will also need to learn to use fdisk. Get into your current system, become root user, and provide us the fdisk -l (this is a lower case L) output. For Ubuntu, you can run sudo fdisk -l on a terminal as a non-root user.

Did you install Ubuntu inside Windows using Wubi? Or did you install Ubuntu to it's own partition on the hard drive?
If you installed using Wubi, then just delete it from Windows control panel. If you installed Ubuntu to it's own partition, simply reinstall the new Ubuntu to the same partition.
I don't think that using 64bit instead of 32bit will solve any problems you may be having. You can use 32bit Ubuntu on 64bit computers. I do.
If you used Wubi, I would recommend doing a real Ubuntu install to a dedicated partition on the hard drive. Ubuntu will run better that way anyway.
See this site for getting started with Ubuntu:

You don't have to get rid of WindowsXP to install Ubuntu. You can easily dual boot both Ubuntu and XP on the same computer. I do. See this site for dual booting Windows and Ubuntu:

And you can get the free Ubuntu manual here:
http://ubuntu-manual.org/
Write back if you need more help.

And welcome to the LQ forums!

There is no way to do a 32bit to 64bit upgrade in Ubuntu. You must do a clean install of the 64bit version.
