Have a 241 GB HP compaq (C), with factory image (D) of 8,53 GB and System (?), made a new partition of 48,1 GB (F) for installing ubuntu. OS W7 Home Premium SP 1. During installation I come to 'GParted' which hasn't got the choice to 'delete' or 'add', only a + and -, change and revert ,so I guessed - = delete ? to get this partition unallocated or free space, forward in 'install' gives the error 'no root filesystem is defined'. By quiting, the bios screen came up with several messages next to those (OK) and went down until .... unmounted.
Because I already took out the live CD, maybe I should have left it in, in order to get the root filesystem ? I don't think I got the allocate drive space part. Many thanks for your kind assistance,
