My Acer swift 3 SF315-51G. It shows no boot device found and I can't start my windows.I tried the solution of changing boot mode to legacy but in my bios menu the boot mode option is greyed out and set to UEFI so I am unable to change it.So please suggest a fix to this problem.

    Hi all,
    I have the same issue and the same picture as @SAKET2611. I have fallow the @egydiocoelho suggestion, however, I got stuck and I some steeps, so I couldn't move it on. I will list my steep below.
    On my laptop, I have plugged ( SSD. m2 120GB windows10 installed, Hd 1TB and flash drive 4GB).
    The list vol only shows the HD and flash, however, the HD is with the wrong letter, it should be d:, because the ssd m2 have windows 10 instaled

      That looks like the SSD hasn't been setup for Windows yet. It has not partitions on it. Did you clone the HDD to it? If not, then that's your next step. Clone the drive, allow the cloning software to adjust partition sizes only on the C: drive. In diskpart if you select disk 1 then list partitions it should show you some hidden partitions that are really small. When the cloning is completed disk 0 will also have them. Once the clone is complete, disconnect the HDD and boot, that will change the default boot image to the one on the SSD. After you've booted from the SSD you can reinstall the HDD and wipe it for use as a data drive.

      Hi @billsey, thank you for you time and your answer.
      I didn't cloned, I just turned off the laptop after windows update. I will follow your recommendation. Could you please provide more detail, what you mean "clone a drive"? Because the HDD (Drive 1) is my data drive and the ssd m.2 (Drive 0) was where the windows was running. The Drive 2 is the flash drive with windows installation (to have access to the cmd) Thank you again I really appreciated!

      The last clone I did was using AOMEI Backupper, but there are plenty of other options. You want to clone the 1TB that has C on it to the SSD, assuming you can still boot from the HDD. If there's no EFI partition on the HDD then you'll need to install Windows from scratch using a flash drive. The Windows installer should convert the drive to GPT and create all the needed partitions before copying files.
