I bought my PC with Windows 10 on it, later installing Ubuntu for dual-booting. Recently, I wanted to replace the HDD inside with an SSD of the same size, so I copied all the partitions to the SSD (GPT partitioning) using GParted and installed the SSD in the laptop.

On startup, GRUB is loaded and I can:

  • Boot Ubuntu normally
  • Select the "Windows Boot Manager on /boot/sda1 or select bootmgfw.efi manually, however it loads a Recovery BSOD, stating the following with options to access the recovery environment (F1) or boot parameters (F8) but those don't work (same screen): 
    File: \WINDOWS\system32\winload.efi is missing or broken
Error code: 0xc000000e

As I understand it, Windows Boot Manager is loaded but cannot find the Windows boot loader (probably because not looking into the right partition), so what I need to do is give the right partition to the boot loader, but I have no idea how to do that.

How do I fix this, preferably something that can be done from Linux and doesn't involve a reinstall of Windows?

  • What is your Linux?

  • Ubuntu (but anything that can be used from a live usb will do)

Reset to default

Enter the following commands in the terminal:

sudo add-apt-repository ppa:yannubuntu/boot-repair  
sudo apt update  
sudo apt install -y boot-repair
sudo boot-repair

Open the Boot Repair application and select Advanced Options > Other Options tab - Repair Windows boot files. The boot flag should be placed on the same partition on which Ubuntu is installed.

  • I tried it but still the same blue screen. For some reason I don't have the option "place the boot flag on", but I added the boot flag on the efi fat32 partition with GParted

  • Does your computer use EFI, and is the disk formatted as MBR or GPT? Do you have a Windows installation media?

  • The disk is formatted as GPT, I'm not sure about EFI but I have an option about UEFI in the GRUB booting menu. I don't have a Windows installation media (I tried to create one but it didn't work, I might retry).

  • Try perhaps Rescatux. You can create it from Linux.

  • I tried the following options from Rescatux, unsuccessfully: File system check: - sda1 (windows efi): OK - sda2 (windows reserved partition 16 Mo, no filesystem): ERROR filesystem check with automatic fix failed - sda3 (windows OS): OK - sda4 (recovery, I guess? ntfs 875Mo): OK Reinstall Microsoft Windows UEFI: - WARNING: backup of EFI directory went wrong - ERROR: the reinstallation of Windows UEFI boot entries went wrong

This worked only because I had kept the old hard drive, but at least solved my problem.

I created a Clonezilla Live USB, and followed their instructions to perform disk-to-disk cloning from the old HDD to the new SSD. It all worked fine and I was able to boot on Windows as well as Ubuntu right after cloning.
