I was using an 1TB hdd with uefi boot window10(updated from 7) and ubuntu 16.04 on it.It worked fine.I first installed windows,and then parted 120gb free space for ubuntu,then I installed ubuntu just by setting installing alongside other operating systems in the installation menu and that's done. I'm not sure if the grub was installed in the windows efi partition or somewhere else, because ubuntu just have two partition, / and the swap.

After that, I got a ssd. I followed the instruction on this page, http://blog.oaktreepeak.com/2012/03/move_your_linux_installation_t.html

and this page:

How to move Ubuntu to an SSD

Copying system from hdd to ssd was ok. I think the problem is with GRUB. I tried both terminal the boot-repair, but in vain. What confuses me is: I find these lines in grub customer grub customer

My ssd is sda. As shown in the picture,it seems ok. But when I boot,I can not find anything about sda. All is about sdb(my hdd).

In details,I created /boot and / ext4 partition andcopied the files from my origin ubuntu accordingly. Then I created a 2mb bios-grub partition just because I failed with grub-install /dev/sda.(I followed a post

,telling me to create this to avoid "this GPT partition label contains no BIOS Boot Partition; embedding won’t be possible" error.

I did this, and succeeded. But still boot from hdd,instead of ssd. So I tried the boot-repair,both recommended repair and advanced(when using advanced,I set ubuntu on ssd as default boot and set to fix grub on sdbX(my windows efi partition)),after that, I still faced the same problem.The strange thing is,I cannot mnt my ssd on ubuntu hdd(still can boot).

Thanks in advance for any reply from you.:)

Can you clarify if you still have both hard drive and SSD installed in the machine? Did you change the boot priority in your BIOS? If the Hdd is still higher in the boot order than the SSD, then it will boot from that first and not even look at the SSD.

OK, It's eventually resolved. I resized my sda so now it only has one partition which is sda1. (before that I copied files on boot partition to /boot)The swap is the old swap area on hdd. Then I used boot-repair tool again.This time it solved the problem. Be sure to open a terminal before the operation because it may probably cannot run during the repair. All I needed to do was copy the code boot-repair indicated and paste into terminal and run and click next, pretty simple. Then I finally boot on ssd.
