I recently bought a second-hand asus t200ta, with a 64bit processor (which I confirmed) but only windows 10 32bit. I attempted to install 64 bit windows, but I encountered a number of errors. I installed the microsoft media creation tool and created an installation of 64 bit windows 10 successfully, but when I load the bios , where you should be able to change the boot order to boot from the second drive, where the installation of windows 10 64 bit is stored, there is only the option of 'Windows Boot Manager', even after I disable secure boot.

I don't know if it is a good idea to do this kind of modification to such an old computer, but here is some advice. Your biggest problem might be compatible drivers, if 64-bit drivers are not available in Windows 10 for your devices.
TheASUS Transformer Book T200TA specificationsindicate the CPU ofIntel Bay Trail-T Quad Core Z3795which is said to be 64-bit capable.
I would start with updating the BIOS. To my surprise, I found a new and very recentBIOS update Version 212dating from 2019/06/10. Be very careful to install a BIOS that fits your model exactly, or you risk bricking the computer.
Once the latest BIOS is installed, you may try to upgrade the 32-bit Windows 10 from the 64-bit boot media that you have created. Skip any demand for a Windows product key, since Windows will activate automatically once it boots.
Before starting, I counsel using a product such asAOMEI Backupper Freewareto create a disk image on external media. Create also the AOMEI Backupper boot media and test it, to see that it can while booting see the external media disk with the image backup.
