But reading https://support.hp.com/us-en/product/HP-14-ac100-Notebook-PC-series/8499318/document/c04981868 finds one of those 32GB EMMC laptops where you can't easily install the OS of choice.
But let's cover a common gaffe. If you format the internal drive (the 32GB) then it's not blank and may never be seen by the Windows Installer ever again. You want this to be blank. I boot up GPARTED (what is and use is on the web) to delete any partitions) so I can try again.
I do not expect Windows 7 to work. W10 might or might not work and you may have to contact HP for factory recovery media and instructions. Figure 50 bucks for that.
I tried to install windows 7 and 10 on the and the installation was interrupted as i formatted the disks and then cancelled the process, ever since then when i try to install a new copy of windows it says that a required CD/DVD driver is missing and then the installation won't continue until I locate said driver. I have tried everything out there and it still isnt working, i have tried usb, cd and tried to switch usb ports nothing is working any ideas??
