My problem is as follows: the hard drive of my laptop has died, the laptop in question is an ASPIR es1 732, so I bought an SSD but I have never been able to boot from the USB drive to install Windows 10.
I have disabled Secure Boot in the BIOS, but the "UEFI" option remains grayed out, despite adding a password as mentioned in various tutorials I found on YouTube.
So I installed the SSD in my old laptop and installed Windows 10, then I put it back into the Acer but I get the following message: No bootable device.
I would like to know if there is a way to create a hard drive with Windows 10 and a recovery partition as it was before so that it can boot from it, although I would have preferred to do a clean installation.
Or disable UEFI, but that seems impossible with this BIOS.
I forgot to mention, the hard drive is detected in the BIOS.

Hello,
First, check that your SSD is properly detected in the UEFI.
It's most likely that your boot USB drive is not set up correctly, and/or the UEFI is not configured properly to boot from it.
And be careful not to confuse BIOS and UEFI, they are two different things. PCs have either a BIOS or a UEFI, with UEFI being the successor to BIOS. The two do not coexist, but it's common to refer to a UEFI as a BIOS due to linguistic abuse.
Most UEFIs allow operation like a traditional BIOS, enabling backward compatibility for OSes not intended for UEFI... However, if the PC's motherboard comes with a UEFI, it's better to keep it in UEFI mode unless there's a justified reason for using a traditional BIOS.
How did you create your boot USB drive? What is its name detected in the UEFI?
EDIT: installing an OS on one PC and then transferring the HDD where the OS was installed to another PC is not necessarily a good idea. If the hardware foundation of the original PC is too different from the destination PC, it can lead to hardware instabilities due to incompatible drivers, etc...
