I have a Lenovo Z570 with Win7 HomePremium 64 bit installed. It already has 4 primary partitions, so used EaseUS to create another logical drive in it. Is there a way that I could install the OS into that logical drive but choose to boot from a USB as I couldn't install grub into the MBR of the disk (may be pre-installed Win7 has something to do with it).
So I would want to achieve something like 1. Normally boot into Win7 2. Connect USB and choose the USB to boot into Ubuntu.
Please advice and help.
