Hello I am currently saving up for a 1TB external portable hard drive that I can install ubuntu 12.10 on but I wanted to try it out first so I downloaded and set up a live usb it froze several times before an hour passed and it happened when i was just using firefox and some other low level programs ... And sometimes some 3d distortion occurred. I have an intel pentium dual core processor and an nvidia graphics card .This makes me slightly scared to try and install 12.10 on a portable hard drive which will basically be a portable pc. If you know how to fix this please help me as quickly as possible ...!
Also how can I install ubuntu 12.10 on the external hard drive without touching windows what so ever and also so that when I unplug the drive Ubuntu will disappear till plugged in again? But would be exactly like I installed it on the internal hard drive speed wise and usability wise...?
P.S. Im on 32 bit!
