Create a USB recovery drive. This can be done from any working Win 10 PC or laptop. Go to Control Panel > Recovery and find the link to create a USB recovery drive.
You will need a 4GB (8GB is better) USB flashdrive and about 40 -60 minutes of time to create the recovery drive.
When created change the boot order in your laptop to USB as 1st option, (is it F12? on startup or try F2 and find it in BIOS) insert the USB flashdrive and then restart the laptop. When in recovery environment menu select Troubleshooting > Advanced > Repair this PC.
DO NOT select reset.
Here is a link that may help you. It details how to change the boot order if you cannot get into BIOS on startup. If this works then you can use the USB recovery drive that you hopefully have made. (A USB should work you shouldn't need a USB - DVD drive)
If this also doesn't work then the only other thing I can think to try is that you have to open the laptop and either remove the HDD (shown 3:45 minutes into video) and then hope that you can get into BIOS with it disconnected and then look for a setting called "Boot Mode", "UEFI Boot", "Launch CSM" or whatever else it may be called, change the boot mode from UEFI to Legacy/CSM: disable the UEFI Boot option and enable CSM Boot support, select USB as the first boot option, re-install the HDD and then try again to boot from the USB recovery drive, or that you find the CMOS battery or CMOS reset jumper on the motherboard, remove the battery or link to reset the CMOS back to default values and then try to get into the BIOS to change the boot order to USB 1st.
