Currently I have a laptop with Windows 10 dual booted with Ubuntu 16.04. I'd like to add a second SSD, move Ubuntu to this SSD, and let Windows have all of the original SSD.

From what I can tell, I can just copy all of my Ubuntu system to the new drive using Clonezilla. Then I'd go on Windows, delete the partitions that Ubuntu previously had, and merge them back to the Windows partition.

Is this accurate? Any steps I'm missing or issues to look out for? Any risk of GRUB not coming up and letting me choose what OS if I have it on the new SSD? I've read a bunch of posts about this, but really don't want to take any chances.

    there are things to adjust after your clonezilla process...when it is dual booted initially.. was windows installed first? – PRATAP Feb 13 at 16:52
  • Hi Pratap, yes, it came with Windows installed and then I created the Ubuntu partition. – L. Thane Feb 13 at 17:09
  • ok..you must be ready with windows recovery usb and ubuntu live usb both for saftey. if i am in your place.. i will keep ubuntu live usb to reinstall grub. – PRATAP Feb 13 at 17:13
  • Good idea, worst case scenario I can re-install everything. – L. Thane Feb 13 at 17:14
  • i guess its UEFI install, the windows..first i will remove ubuntu folder from EFI partition to allow booting directly to windows and get rid of grub. once clone zilla process is done, will reinstall grub on EFI partition though UUID conflicts may rise. lot of links available to understand EFI partition, grub, UUID in askubuntu.. dont proceed without understanding them.. – PRATAP Feb 13 at 17:16
