i recently tried installing "ubuntu" onto a old laptop/ acer "emachines" em250 and it said that the pc wasnt fast enough and should try "Lubuntu" instead so i did when "lubuntu 14.4.01" the copy of ubuntu was only a pen drive "bootable" but when it displayed the options on "lubuntu" it said
"full install beside windows"
"wipe windows install linux"
I chose wipe and install on system. Only its now not bootng correctly and says its fully installed but fails to boot. When it does it has constant disk issues and partition errors...... how do i absolutely remove the os format and partition ready for clean install of linux.
