I am trying to run Ubuntu on Acer 4520 Amd 64 Machine. I downloaded ubuntu-11.10-desktop-amd64.iso and prepared a pendrive to boot the machine from.
The machine prompts me to select from one of the options like "Run Ubuntu from USB" / "Install Ubuntu..." / etc.
I tried multiple times to run Ubuntu from USB, but clicking on it runs several lines of some code that I do not understand and after some time it just stops.
The machine has various partitions. On D the previous version (I think 8.04) of Ubuntu was installed which stopped working at some point so I formatted the partition using Disk management utility in Windows recently. This might be causing some problem, not sure.
I would appreciate an early help in this regard.
