EFI/Mircrosoft/Boot/BCD How do I get the computer to run with a usb cord through my laptop?

This error code 0xc0000034 usually indicates a problem with the boot configuration data (BCD) file on your Toshiba laptop.
The BCD file stores boot configuration information and is required for Windows to start up. The most common cause of this error is a missing or corrupt BCD file.

You can try the following steps and can try to resolve this issue:

1. Boot into the Windows Recovery Environment (WinRE)
2. Launch the Command Prompt.
3. Type the following command to rebuild the BCD file: "bootrec /rebuildbcd".
4. Press Enter and follow the on-screen instructions.

Note: If these mentioned steps do not resolve the issue, you may need to perform a repair install or a clean install of Windows.

Unplug all external devices and restart the computer to check if this helps you to get to the desktop screen. If you have a laptop ensure to plug in the power cord to the socket.
You may want to download the ISO file and save it to the USB flash drive using the media creation tool.

Step 2, boot laptop/PC using USB stick
Step 3, let stick boot up and follow instructions until you see repair windows install, go through options and select command prompt.
Step 4, When you are at the command prompt run these options :-
Bootrec /fixMBR
bootrec /fixBoot
bootrec /rebuildBCD
once done type exit.
Step 5, reboot as normal ......... and hopefully you'll be back in windows 10 with no lost of data.

Windows 8 Boot Error Fix 0xc0000034 with Command Line Tools
try this link it might help you out.

First change your RAM and again try recovery

1. Use Device Manager's Firmware option and select Boot from EFI Internal Shell.
   
2. Use the EFI internal shell, as follows:
   
   1. Start the EFI internal shell from the EFI boot menu and select the drive with the Windows product DVD or Windows PE. The following example assumes that the drive is Fs0:
      
      Shell> Fs0:
   2. Start the EFI boot application. For example, on an x64 system, run the following command:
      
      fs0:> \EFI\BOOT\BOOTX64.EFI For an Intel Itanium system, run the following command:
      
      Fs0:\EFI\BOOT\BOOTIA64.EFI
   3. After the application starts, you may be immediately prompted to press a key to boot from the drive to continue. Press a key to continue booting from the installation media.
      
      
   4. After the installation is complete, you can check whether Windows used the EFI boot environment by running DiskPart and verifying that the drive is formatted using the GPT file structure and that the ESP and MSR partitions are present.
      

It seems that the Boot Configuration Data (BCD) is corrupted.
Microsoft has completely reengineered the boot environment for Microsoft Windows Vista to address the increasing complexity and diversity of modern hardware and firmware. One aspect of this reengineering is a new firmware-independent data store that contains configuration data that influences the boot process. This paper provides an overview of this configuration data - called boot configuration data (BCD) - and describes how to use the related tools to manage boot options.
Step 1
Perform chkdsk which will repair the bad sectors of the hard drive.
To do this, follow these steps:
1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

2. Type chkdsk/ f, chkdsk/r, chkdsk/i, chkdsk/c in the commands listed below i.e. (/f, /r , /i, /c).
Step 2
Try to load BIOS to default and check if you have similar issue.
Step 3
I would suggest you to rebuilt BCD. To do this, follow these steps:

4.Press 1 (One) to select windows XP and then hit enter.
5.When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.
6.At the command prompt, Type Bootrec /RebuildBcd and then press ENTER.
7.If the Bootrec.exe tool runs successfully, it presents you with an installation path of a Windows directory. To add the entry to the BCD store, type yes. A confirmation message appears that indicates the entry was added successfully.
8.If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command.
Bcdedit /export C:\BCD_Backup

ren c:\boot\bcd bcd.old

Bootrec /rebuildbcd

Note To start the computer from the Windows Vista DVD, the computer must be configured to start from the DVD drive. For more information about how to configure the computer to start from the DVD drive, see the documentation that is included with the computer or contact the computer manufacturer. Back to the top Bootrec.exe options loadTOCNode(2, 'moreinformation'); The Bootrec.exe tool supports the following options. Use the option that is appropriate for your situation.

Note If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD, and then run this option again. By doing this, you make sure that the BCD is completely rebuilt. To do this, type the following commands at the Windows RE command prompt:

• bcdedit /export C:\BCD_Backup
• c:
• cd boot
• attrib bcd -s -h -r
• ren c:\boot\bcd bcd.old
• bootrec /RebuildBcd

/FixMbr loadTOCNode(3, 'moreinformation'); The /FixMbr option writes a Windows Vista-compatible MBR to the system partition. This option does not overwrite the existing partition table. Use this option when you must resolve MBR corruption issues, or when you have to remove non-standard code from the MBR. /FixBoot loadTOCNode(3, 'moreinformation'); The /FixBoot option writes a new boot sector to the system partition by using a boot sector that is compatible with Windows Vista. Use this option if one of the following conditions is true:

• The boot sector has been replaced with a non-standard Windows Vista boot sector.
• The boot sector is damaged.
• An earlier Windows operating system has been installed after Windows Vista was installed. In this scenario, the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe).

/ScanOs loadTOCNode(3, 'moreinformation'); The /ScanOs option scans all disks for installations that are compatible with Windows Vista. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista installations that the Boot Manager menu does not list. /RebuildBcd loadTOCNode(3, 'moreinformation'); The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista. Additionally, this option lets you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD.
