Hi I have hp pavilion 2123 with hdd and my OS is Windows 7. But i replaced my hdd to ssd and OS is Windows 10 it works but when i replaced another ssd its not working saying no bootable device and then i repplaced again the first ssd put it back then still not working no bootable device found. even booting in usb does not work. When i go to bios setting i cant fine the legacy support but if i put my hdd OS windows 7 it works.

I need help for this because i want to use ssd for better performance.

Thank you!

You said you replaced the HDD with Win7 with an SSD with Win10 -- but you didn't mention doing an Upgrade, so my guess is that you INSTALLED Win10 to that SSD, right? And then, the Win10 SSD boots OK, right.

But then you said you tried a secon SSD, but you didn't say what was on it or how you configured it. So, we have no we of knowing why that second SSD did not boot.

The best approach is to "clone" the HDD to an SSD; that way, you can be sure that all the critical partitions are copied, and to the right locations.
