PC not booting, 'Non-System disk or disk error'

[talalhashimkt]

When I press the power button, this happens: https://drive.google.com/file/d/1c830s8vCX8pHLTNb_zHShDDQZrAkO_tA/view?usp=drivesdk

Lately I have been trying to install different distros of Linux and I have been playing around with partitions.

I have tried everything on this page except the 2 last ones (re-installing windows, but I can't do that because I can't access windows).

Hi

Well the video shows an Intel Boot Agent"initialising and establishing link"  whoops initialiZing.

 and then a Non System Disk error.

So BIOS and select SECURE Boot rather than Legacy. 

If you can change the Boot sequence to put DVD or USB above the Hard Disk then do so.

So you want to make a DVD/USB with a half decent linux on it, like Lubuntu for instance.

This may accidentally give you back your W10 boot manager.

Get a bootable Linux running as your first step. 

This may involve repeatedly pressing ESC as you boot and then F9, or some other sequence to boot from an external device.

You should be able to download windows from MS

https://www.microsoft.com/en-us/software-download/windows10ISO

using Linux/Lubuntu and save a copy onto another USB, but this is not guaranteed.

So step one is to avoid/disable the Boot Agent and get a bootable device, then ask again.

You need to read this in detail if you're going to mess around with Linux distros:  https://help.ubuntu.com/community/UEFI

I fixed my problem. I created a windows 10 installer USB from your link and booted with it. One of my partitions had to be replaced so I replaced my c drive, which has all my programs (fortunately all my files are in another drive} so right now I'm installing all my programs again.
