Hope this helps, and if this is your only computer I would suggest to use the Windows 10 'Media Creation Tool' (download from Microsoft website) to create a separate recovery flash drive in case anything goes wrong and you need to go back to Windows 10. This leaves all your data in a 'Windows.old' folder on the hard drive.
When you install Windows 7, no need to format the drive just install over the Windows 10 partition (it should be a big one). It should restart to Windows 10, now follow instructions here to install it from a USB this website explains it, you want to follow instructions for the Intel N3000 series / 'Braswell' chip. The computer should reboot and then once you're in the UEFI settings menu, you need to disable 'Secure Boot', and Save changes and Quit in the firmware.
When a menu comes up, choose 'Troubleshoot' -> 'Advanced options' -> 'UEFI firmware settings' (or equiv) Windows 7 *can* run on your laptop although you'll need to put a bit of effort in.įirstly, you need to go into the UEFI BIOS and change some settings: I've bought New PC match OEM license of Windows 7 Professional Service Pack 1 but I have special software that only works Windows XP professional sp2 or sp3 so I don't know I'm able to downgrade to Windows XP Professional SP2 or SP3,isn't it.Thank you. I would not go to XP having W7 for the simple reason that XP does not support SSD.
