Hi,
If possible, access msinfo32.exe in the start menu, take a screenshot and post it here.
This way we can see if it meets the requirements for Windows 10.
Regarding the Windows 10 installation, the best method is using the USB flash drive process, booting into the BIOS and starting the installation instead of updating. However, you have to back up your files beforehand because this process will wipe your HDD/SSD drive.
Thanks
