I am using a usb to dual boot windows home premium with ubuntu 14.04. But my problem is that whenever i Choose the option Install Ubuntu with windows side by side and click on install my laptop starts afresh the ubuntu installation from the first step. If i remove the usb just after clicking install then windows boots again. Please help me.
I would recommend you to manually select (considering you create them first) separate partitions for ubuntu.
My current setup:
- C (win8.1)
- D (NTFS shared with both windows and ubuntu)
- an extended partition containing an ext4 (mount point /) and a swap
