Window 10 access is denied

Hi Kosta. I'm Greg, 10 years awarded Windows MVP, here to help you.

The last error you get means you have Windows installed on the old Legacy MBR drive which uses a System Reserved partition and not EFI System.

Since you have already deleted the partition it is too late to do the proper repairs, you can proceed with creating the System Reserve partition used for Legacy MBR:
Managing System Reserved Partition in Windows 10 | Windows OS Hub

There is an option to construct System Reserved from Diskpart in Command Prompt on bootable media, or to move boot loader to C which is allowed in Legacy MBR installs.

If rebuilding System Reserved succeeds then I'd convert Windows drive to UEFI using this method:
https://www.makeuseof.com/windows-10-11-convert... However you cannot convert to UEFI if there is no separate System Reserved partition.

If this does not work then because Windows should be installed to UEFI anyway, I would wipe the drive to reset formatting and do this gold standard Clean Install which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki.... Read over it first, take notes, ask back any questions so you're prepared.

To create bootable Windows 10 Installation Media (on another PC if necessary) install Media Creation tool and follow the steps toward the bottom of the download page here in the section "Using the tool to create installation media:"
https://www.microsoft.com/en-US/software-downlo...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key for your PC maker given in this chart: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, then on second screen choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, select the Unallocated Space, click Next to let it create and format the needed partitions and start install - this makes it foolproof.

There is a step to rescue your files first using the booted media if you don't have them backed up: http://answers.microsoft.com/en-us/windows/wiki...

You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the linked tutorial. It's a great learning experience that will make you the master of your PC because you will learn everything that works best and how to apply it with your own hands.

Feel free to ask back any questions. Report back results for more steps if necessary.

When I am going to hear from someone?

Kosta

I apologize for not helping you to resolve the issue.

I've exhausted all the solutions I know

I'm going to open your question back up so that other Experts can try to help.

Greetings

Hi,

You will need to create the EFI partition

1 - Boot with windows bootable pendrive and open DISKPART again

• Type: list disk

(the list will show the disks)

• Type: sel disk 0

(disk 0 will be selected)

• Type: list partition

(disk partitions will be listed)

• Type: sel partition X

(replace the X with the partition with type primary)

• Type> shrink desired=500

(this will create a 500mb partition)

• Type: create partition EFI size=200

(create EFI partition)

format quick fs=fat32 label="System"

(format the EFI partition)

exit

(to exit Diskpart)

2 - Now run the commands:

bootrec /fixboot

bootrec /fixmbr

bootrec /rebuildbcd

exit

After that, restart the machine normally, removing the DVD or USB stick you used
