HI again,

So I used the bootable USB, but I wasn't able to repair my computer. I get a message on a blue screen that says "Startup couldn't repair your PC". Is there another method I could perhaps try?

Hi:

 

Yes, refer to that other link for how to use the command prompt in the repair section to run repairs to the master boot record.

Before you can do anything, you have to check whether you have a MBR or a UEFI system.

Paul's advise is just for MBR.

In UEFI it is completely different.

Hello again,

I tried doing as the article showed, but when I type "bootrec /fixmbr" it says "A device which does not exist was specified". Going off of what the other person who replied to the last message said, I think I might have an UEFI system 😕

Hi:

 

If the OS has been installed in EFI mode, see this dell document on how to make repairs.

 

How to repair the EFI bootloader on a GPT Hard Drive for Windows 7, 8, 8.1 and 10 on your Dell perso...

 

You can follow the instructions from the command prompt on, since you already know how to get to that section when you boot from the W10 installation media.

 

If that doesn't work, you can use the installation media to reinstall W10.

 

To recover any files you need to save, do not delete or format any partitions.  Just let Windows install over the current Windows partition, and it will create a Windows.old folder.

 

After W10 has completed installing, you can explore the Windows.old folder, find your old user profile, and copy and paste the files you need to save to your new user profile.

 

I recommend you also save them to a USB flash drive or portable hard drive for safekeeping.

The DELL articel is completely nonsense! They also don't understand UEFI and copy the errors from everywhere.

 

Only one (1) command is valid!

bcdboot c:\Windows /l en-us /s B: /f UEFI

 

You have to choose the right letters. from >>diskpart<<

otherwise your data are lost!
