Windows 10 UEFI Problem

Have a Windows 10 HP Notebook that, after booting, would get "Your PC will automatically restart in one minute."
In attempting various repairs, I finally got to the bootrec fixes. The last one, bootrec  /fixboot failed with "access is denied."
I went through the Diskpart fix and at the last step "cd /d G:\EFI\Microsoft\Boot" I get another "Access is denied"
I had the UEFI partition named "G"
I'm at the point where I can only boot from a Windows 10 USB that goes right to the "Install" function.
Going to "Repair your PC" or Install.
I can access the Repair..." and that's where I've been trying the fixes in Command Prompt"
Kinda lost, here.
Any help appreciated.

Boot the PC in safe mode then uninstall any third-party antivirus on your system or recently installed Windows update and test the result.

Also try AHCI / IDE for SATA mode.

Scan your PC with a bootable Antivirus for Virus.

From a bootable USB Key, also test the hard drive for errors using the Manufacturer's hard drive test application.

If not this and not a virus as suggested in the prior post, it may be some logical damage to the operating system, in which case you may have to reinstall Windows 10.

if none of the above worked then you have to check the system for a defected hardware.

Since I can only boot with W-7 usb, or other ,I can't do the suggestions.
Can boot with a 3rd party USB, Spotmau, been using for years.
Able to rest the drive which is OK.
Diskpart shows:
Volume 0     F      DVD
Volume 1   C    Windows  NTFS    Healthy
Volume 2            EFI            FAT32      "
Volume 3                              NTFS        "
Volume 4    E    Recovery    NTFS       "
Volume 5     D  ESD-USB  FAT32        "
can you post a screenshot of that diskpart plse?
since you have a dvd - you should be able to boot from that also; and since you can boot from an usb stick - you can also boot from other bootable sticks
i would run ram and disk tests first, to Ensure the basics are ok; i use the UBCD (can be run from cd, or USB stick)
Hardware diagnostic CD    UBCD
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
direct download :
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)      

**  you can make a bootable cd - or bootable usb stick
*** note *** for SSD drives  use the tool from the manufacturer, like intel 's toolbox :

for completeness -here's how i handle disk problems :

==>>****in order to be able to  boot from CD or usb - you may have to disable secure boot in the bios
