Can you type me the exact message that you’re now getting on your screen?

I am not sure what the results were of the other methods, but from this point onwards.

Perform a full backup of your Windows system (I recommend Macrium Reflect). Your PC may be unbootable if the repair is not implemented correctly.

Boot the computer using the Windows 8/10 installation bootable DVD/USB. Make sure you boot the media in the same configuration as your UEFI installation.

On the ‘Windows Setup’ wizard click on ‘Next’ and click on ‘Repair your computer’. You will then see a blue screen and an option to choose. Click on ‘Troubleshoot’ then click on ‘Advanced Option’ and then click on ‘Command Prompt’. Type these commands on the Command Prompt for UEFI configuration:

diskpart (opens Disk Partitioning tool)
select disk 0 (or whichever disk is your system disk)
list volume (please note the number of the volume that has no drive letter assigned and has FAT32 listed in the FS column, usually the only FAT32 volume/partition)
select volume x
assign letter=Z: (gives drive letter Z: to EFI System Partition)
list volume (to check drive letter Z: is correctly assigned)
exit (closes Disk Partitioning tool)
cd /d Z:EFIMicrosoftBoot (changes current folder in Command Prompt window)
attrib Z:EFIMicrosoftBootBCD -h -r -s (removes hidden, read-only and system attributes from BCD folder)
bootrec /fixboot (writes a new boot sector to the system partition)
ren Z:EFIMicrosoftBootBCD BCD.old (renames BCD folder to BCD.old)
bcdboot c:Windows /l en-gb /s b: /f ALL (en-gb is for the UK - use your own locale)
Installation Checking

Your boot configuration is probably correctly configured if the following commands report correctly.

Confirm the PC boots
Run bcdedit and confirm boot configuration is correct. You can use bcdedit /enum all for the full details,
Run reagentc /info and check recovery configuration is correct. In my case, Windows RE was not configured and I had to run regaentc /enable to enable it.
Run bcdedit /export and confirm the command works. Minitool Partition Wizard may be used to explore the EFI system partition and confirm the correct files have been copied.

You’re already at risk of losing documents if the issue is with your hard disk (etc). If data is crucial, you would be better off copying it to an external drive by connecting drive externally, and then doing the steps.

Boot from a Windows 8 bootable usb or disc and go to command prompt, then run the following commands

attrib -r -s -h c:bootbcd
del c:bootbcd
bcdboot C:windows

Can you power off the tablet completely, then make sure once its powered on its set to boot from the usb?

No, you should not attempt to recover it with a Windows 7 disc because the repair files will not be the same for Windows 10. If you want to replace Windows 10 with 7 then boot from the 7 disc and do a clean install of Windows 7.

Rufus gives more choices then the Windows Media Creation tool. You can use the one you prefer.
