I have a Lenovo y510p system with Windows 8.1 pre-installed. It has UEFI with secure boot and I want to dual boot Windows 8.1 with Ubuntu 14.04.2.
I am not a too tech savvy person and want to look at the Ubuntu flavor if it suits me enough to move.
I tried installing the GRUB2 on the "/sda" (my main HDD) but after I boot to windows even once, the GRUB2/bootloader no longer starts. To prevent any mess up of my system (read Windows 8.1 loader), I plan to install the Ubuntu bootloader on an USB. It would be great if any one can help me with the following on the same:
I plan to re-install Ubuntu 14.04.2, so during installation can I go to "Something Else" and use my main HDD (/sda) for installing the Ubuntu (i.e. "/" and "/home") while use an USB flash drive to install the "/boot" (boot loader) partition ?
Can the above be done, I mean to what mount point is the "/sdb" flash drive be mounted for it to install the GRUB2?
If the above is possible will I need to always plug in the USB once I have booted in Ubuntu or I can simply remove it after Ubuntu has started?
This mean that the "/boot" is no longer on the system.
Over all is there any way I can install Ubuntu on HDD such that when the USB is not plugged in I go to my Windows system and when I plug in the USB I can boot to GRUB2 menu on the USB and go to Ubuntu. Will the above scheme work ? Please do correct me, as I know I can be wrong.
Thanks in advance for all the help I have already found on the Ask Ubuntu forums.
Thanks and Regards

For the first question this link might help you a little bit http://tinyurl.com/q6tm77t
If you'll install the bootloader on USB, then the USB will have to be always plugged in whenever the computer starts.
