I migrated data on my laptop's HDD which contains Windows 8.1 to my SSD and replaced the HDD with the SSD (My laptop has 2 hard drive bays btw). Currently, my Windows 8.1 and Ubuntu 14.04 are on their own SDDs. Before this, I was able to boot straight into the GRUB OS selection screen where I could select to boot into Windows 8.1 or Ubuntu 14.04. But now, every time I start my laptop, I get this screen

enter image description here

Once I type exit into that command line. I get this screen (btw, I have reconfigured to remove the duplicate entry for Ubuntu after I took this screenshot) enter image description here

After selecting ubuntu I am able to see the OS selection screen. enter image description here

Also, when I am in Ubuntu, and restart, it boots directly into Windows without showing the GRUB command line screen. My question is, how can I boot straight to GRUB OS selection screen on startup?

The current boot order entries. enter image description here

Thank you very much

Try this from an Ubuntu Terminal Window:

sudo efibootmgr -o 0

That should fix the problem. Alternatively, you could use EasyUEFI in Windows to move the ubuntu entry to the top of the boot order list.

EDIT:

If it's resetting to boot straight to Windows when you reboot the computer without booting into Windows, then your EFI is badly broken. Check the manufacturer's site for an update (probably called a "BIOS upgrade" or something similar). If that doesn't help, then the best course of action is to return the computer for a refund, assuming you're within the return period. If not, you'll need to employ an ugly hack involving renaming boot loader files. Boot Repair can do this semi-automatically with an option on its Advanced menu, or you can do it manually, as noted here. Either way, if it's a bad EFI, write to the manufacturer to complain! Too many have been delivering junk EFIs for too long!

If this happens only after booting to Windows, then chances are Windows is the culprit. This question covers this variant of the problem.
