I have bootable ubuntu usb and everything is working fine. Note that I can boot only from usb or cd/dvd.

Now I want to install new programs, edit my own files etc... So I thought that the best solution would be to

  • boot fom my external (160GB WD) or
  • have root directory automatically mounted to the external hdd when booting from usb

Is any from above possible?


I'm currently running my Acer Aspire 5440 laptop off of an external WD Passport 500gb hard drive, and have been for a year now. I haven't had any issues with it, other than the occasional disconnect issue. I don't see any performance problems with it, as long as the computer has a good set of hardware, RAM, video, processor, etc.


All are possible ! The only thing that will bother you is the performance issues that will be very poor due to USB 2.0 input - output (read - wright) performance limitations.
