Install Windows 7 on 14-ac107nl with eMMC

[Lorenzo995]

Hi, I have an HP 14-ac107nl and for space and speed problems I would like to make a downgrade from windows 10 to windows 7. The PC has an eMMC memory and I can not complete Windows 7 installation (error 0x80070057). There is a procedure for to do it?
Thank you

Hi,

             This error occurs because the partition that is reserved for system is damaged

                   Here is the solution.

1. Boot into windows 7 setup.
2. Delete the system reserved partition and C drive. (You must need to delete C drive in order to rebuild system reserved partition) 
3. Select unallocated space then select next.
4. Follow on-screen instructions to install windows 7.

Note: Make sure you have enabled legacy mode in BIOS and installing windows 7 on MBR partitioned disk drive for successful windows installation.

Good luck

Thank you for the reply. That's exactly what I did.
I tried it many times but the installation stops and reports the error at the last step

Sorry for my bad english and thank you for the help!!

I think the problem is that the Windows 7 installer does not have the eMMC memory driver, so it does not work. Where can I find the "Intel Rapid Storage Technology Driver 14.5.2.1088 Rev.A" driver ???

Hi,

                    I don't understand why are you thinking about eMMC memory. If you think it is making problems then remove the chip and then install the windows7. Once installation completes download and install Realtek card reader driver from here
