To switch from one architecture to another, a fresh install is really the only viable way to do this, i.e. download an iso, write it do a disk such as a flash drive or CD, boot into said disk, then install. A way to make future installs easier is to set /home to a separate partition, the Xubuntu installer supports that, but you'd have to do the partitions manually. --c_smith <div class="gmail_quote">On Nov 17, 2013 11:13 PM, "Tristan" <<a href="mailto:twistycat_shino@hotmail.com">twistycat_shino@hotmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div bgcolor="#FFFFFF" text="#000000"> So I recently have installed xubuntu on my windows 7 laptop, mainly for the express purpose of being able to access my school from it through the terminal. I have since kind of fallen in love with this new OS even though it may not cover all the functions my laptop has to offer through windows 7, but that is beside the point. I installed xubuntu 12.04 on my laptop from a live disc given to me by my professor, and so me not thinking didn't realize it was 32 bit. At least I think...I ran the command uname -m in the terminal and it gave back i686 which supposedly means I have a 32 bit OS. Without a doubt, though, I know I can run 64bit I have a 64bit windows 7 and a i7 4700MQ processor. Now my only problem is switching this 32bit OS to a 64bit one. I would think this is as simple as setting up a live usb stick for 12.04 64bit xubuntu, which I would need a few pointers on. However I just want to make sure I am not going to destroy my laptop. So to state the obvious how do I change my 32bit OS to a 64bit OS and is it safe?
