Windows 7: Failed bootable USB creation

Failed bootable USB creation

Hi all,

I tried to create a bootable USB using the info here: How to make a hard drive bootable? - Forums - CNET

I am now able to partially boot from the USB, but I cannot boot from the HD anymore. When I remove the USB, I get a Windows Boot Manager error that Windows failed to start. I get:

File: \Boot\BCD
Status: 0xc000000f
Info: An error occurred while attempting to read the boot configuration data.

I assume I did something wrong in creating the USB or somehow changed the machine so it will no longer boot from the hard drive.

A little help please...

Have you tried to run System Repair?

I'm not sure what "partially boot" means.

Yes, I have tried System Repair, but it will not run. By "partially boot" I mean I get into system Recovery Options, but it won't allow me to use them.

Are you saying you are trying to boot Windows 7 from an external usb hard drive ?

Please explain.

AddRAM, I found this comment from the opener:
"...I assume I did something wrong in creating the USB or somehow changed the machine so it will no longer boot from the hard drive..." Very likely, thread starter would like to be able to boot either from the internal hard-drive or from the usb device but not booting Windows 7 from the usb, that's my guess.

Or if he indeed is just trying to create a usb installer, he`ll have to clarify better.

If that`s the case then just use Rufus

In this case, it copied boot files from D Windows to C.

It does the same thing startup repair would do, writes the system files to C and I guess it may mark that partition Active.

PM Wolfgang the author, he`s always been helpful to me
