partitions - getting in a mess!
Absolute beginner - don't yet understand most of the jargon in related threads. Have tried to install Mandrake 10.1, failed half way through with partitioning. Changed to Edubuntu, ok from live cd so tried to install. Again went very well until error 'failed to detect a file system'. Clicked 'ok' and then it froze at 'detecting file systems' - 15% through install. Am trying to install on external usb hard drive (250GB) and opted for 'erase' prior to partitioning. Now the hard drive does not register on windows. Can anyone suggest an idiot's guide to a way forward?
