How to change the boot priority order on Deepin
 

I need to clone the HDD which has a dual boot set up of Windows and Deepin to a newly installed SSD. Due to an issue with the Linux partition, I can only clone the Windows partitions and set up a dual boot on SSD later. To make sure the Windows will work on SSD, I need to change the boot priority order on HDD first. I, however, can't see how I can make such change shown on https://itsfoss.com/uninstall-ubuntu...dows-dual-boot. I guess that the article uses Ubuntu and Deepin is different from Ubuntu in this regard.

How to change the boot priority order or other approaches?

There are two places where a boot order is set:
1. In the BIOS settings on the hardware, and
2. In the boot manager (Normally GRUB2 on most dual boot machines).

Did you try the +- keys to move the highlighted entry up or down and then f10 to save?

No, the on-screen instruction says to use the up or down arrow keys.

After setting the boot order, you need to 'exit' 'save & exit'.

Only options F2 or F12 are a boot order from various devices, but not a boot order in the same device which the dual boot is.
