\EFI\Boot\bootx64.efi

When I manually select this entry by pressing F9, Boot From EFI File, Windows boots.

That path works for my laptop. I already have OS Boot Manager which is the default entry which boots Windows from a 2.5" SSD drive. But if I add that path to the customized boot mode, the BIOS lists Customized Boot in F9 and I can boot Windows from it. In other words, I now have two bootable entries.

 

Not sure why it doesn't work for you. You are in the uefi native mode, right? When you typed in the path, did you click the Enter key before you got out of the Boot Options?

 

You can try again. When you go to the Define Customized Boot, do you see the boot path you have just entered? If yes, delete it (you'll see the instruction there). Then type \EFI\Boot\bootx64.efi, click Enter and click ESC to get out of Boot Options and save and exit. If you still have a no boot image error, go to the uefi boot order in the Boot Options and manually place the Customized Boot entry on the top of the list and save and exit and see what will happen.

@Tk_srq,

=> yes

When you typed in the path, did you click the Enter key before you got out of the Boot Options?

=> yes

 

When you go to the Define Customized Boot, do you see the boot path you have just entered? If yes, delete it (you'll see the instruction there). Then type \EFI\Boot\bootx64.efi, click Enterand click ESC to get out of Boot Options and save and exit. If you still have a no boot image error, go to the uefi boot order in the Boot Options and manually place the Customized Boot entry on the top of the list and save and exit and see what will happen.

=> Done but the laptop still doesn’t boot itself

 

Just to precise again, I want to boot on a msata drive, not a 2.5” ssd. I think the problem has to do with UEFI because I can boot on another MBR formatted msata (Boot Mode = UEFI Hybrid with CSM)

I didn't know your other msata runs on the mbr partition in the hybrid uefi mode. 

 

If I switch to the hybrid uefi, my laptop boots normally, so I thought the hybrid uefi is just the modified form of the uefi that still runs on the gpt partition.

 

Well looks like your bios doesn't support the uefi boot on an msata drive. The bios seems unable to automatically create a boot entry to launch the boot loader from the efi partition, even though you can manually run the boot loader to boot Windows.

 

If you still want to run the new msata in the uefi mode, you may check the mbr to gpt conversion method provided by Windows. Here are just a couple of references below. If you want to try this, you first need to install Windows on the new msata in hybrid uefi mode and then covert the drive to the gpt partition. You can even try this on your old msata to see it works or not.

Hi Tk_srq,

Thank you very much for your help.

I finally found a way to bypass the non-boot on msata.

 

I created new 16MB MSR and 100 MB EFI partition on HDD drive and then create a new bootloader on the EFI partition (with help found on How to Repair EFI/GPT Bootloader on Windows 10? | Windows OS Hub (woshub.com)).

 

The system now boots from EFI partition on HDD which launch the OS installed on the msata, the whole thing in native UEFI 🙂
