Windows 10: Boot problem Windows 10

Hi, yesterday, in my PC with Windows 10 installed, I opened Windows 7 installer and pressed "Install now", I immediatly cancel the operation and a new partition next to C: showed up. I knew nothing about system partition, so I thought it was a new partition created and reserved by Windows 7 installation, so I proceded to delete the stuff inside (EFI and Boot folders). After that I restarted the computer.

Now without those folders I can't boot Windows 10, and it shows me the error: "Reboot and select proper boot device". I looked up for many tutorials but any of them worked.

I also tried to fix it by using Troubleshoot option with Windows 10 img started from a bootable USB but all the options fail.
I would like you to help me to delete all the partitions in my disk except the one container of Windows 10 SO (I can't lose those files inside, otherwise formatting would be an option), and then recreate the necessary partitions (System, etc.) and generate the necessary files to bring the OS back to life (hope it's possible).

Thanks for reading.

:)

Windows 10 Problem

After I updated Windows 10 today as I was instructed, I can no longer get on the internet. My wifi no longer shows up to click on it. It was working fine until I allowed the install. I have tried restarting the HP Spectre x 369 laptop and the router,
but this has not helped. (I am using a borrowed Apple computer to search for a solution.) I need help to get back online. Can anyone help or tell me who I might contact for help?

 

You may have deleted your main EFI folder, go into the BIOS/UEFI on your computer and turn off Secure Boot and if required turn Legacy Support on, then test to see if you can boot.

Then you could try doing a Windows Repair if you are able to get into it.

BCDBoot is a command-line tool used to configure the boot files on a PC or device to run the Windows operating system. You can use the tool in the following scenarios:

Repair the system partition. If the system partition has been corrupted, you can use BCDBoot to recreate the system partition files by using new copies of these files from the Windows partition.

BCDBOOT <source>

<source> Required. Specifies the location of the Windows directory to use as the source for copying boot-environment files

The following example initializes the system partition by using BCD files from the C:\Windows folder:
