If it were me I would download the ISO Image of Ubuntu for X86_64bit architecture.
Done. Put in the new Ubuntu install and when it comes time to partition choose 'manual'
Yes. Delete the 32bit Ubuntu install partition (journaling file system) that you already created.
I'll copy any of my files onto a usb drive, first. Delete the 32bit Ubuntu install swap that you made.
Now take advantage of that free space from the old partitions that you just deleted and create new partitions.
-Highlight the free space
-Create a new partition (make your (/) ext 3 journaling file system 20GB
I have a 1 TB HD. About 500 GB belongs to Ubuntu, the other 500 GB belongs to Windows. -Create another new partition (make your swap space ....2GB
This will only account for 22 GB of the 500 GB available. Is there an implied step, that I am missing? Done, finish and write to disk--
That would be great...
I will wait to hear back from you before proceeding. Thanks!
