The other answers given here work great on MBR/BIOS systems, however if you're on a UEFI system like I am, bootsect will just write a semi-functional boot MBR over the GPT protective MBR and bootrec just gives an "Access denied" error message, and neither one has a functional option to fix a broken EFI system partition, which on a UEFI/GPT drive is what contains the bootloader that used to be stored in the MBR. There's unfortunately almost no up-to-date guides on fixing the UEFI Windows Boot Manager (almost all of them just say to run the graphical Startup Repair utility, but that doesn't fix the problem in all cases), but I finally found the correct solution buried in this article, which requires the use of the bcdboot command instead:


(Optional) If you are not currently dual booting and want to fully clean the ESP before writing a new bootloader, run format N: /FS:FAT32 to reformat it as FAT32. This is probably not necessary under normal circumstances, however, as bcdboot seems to do a good job of cleaning things up itself. Especially do not do this if you have a Linux distro on another partition or else you'll have to reinstall GRUB as well once you're done with this. Also note that the following steps should not affect an EFI GRUB install as long as you do not otherwise delete GRUB's existing directory on the ESP.

Finally, write the new bootloader to the partition with bcdboot C:\windows /s N: /f UEFI. This command rebuilds a new UEFI-compatible bootloader on the ESP mounted at N: using the Windows installation mounted at C:\windows. Once it's done, you can verify the new bootloader was written by running dir N:\EFI, where you should see a Microsoft directory containing the new Windows Boot Manager as well as a boot directory containing the fallback bootloader (along with other directories for any other bootloaders you have installed, such as GRUB for Linux).


I have a Windows 7 installation that doesn't have a boot loader on the disk.Basically, the story goes;I had two disks on my PC where one of them served as the system disk with Windows 7 installed, and then a storage disk. The system disk was starting to present some disturbing errors and mystical freeze lags, so I decided to get a new disk to serve as the system disk. When I then installed Windows 7 on the new disk, I was planning on keeping the faulty disk as it was still spinning, but forgot to disconnect it during the new installation. I'm guessing this is why the installer never created a boot loader partition on my new disk automatically.As long as my old system disk is running, I'm able to boot into my new installation (I get two options in the boot loader menu), but now it's failing more and more, and I need two or three reboots in order to even get to the boot loader menu.


So, the question is; is there any way to install a boot loader to my new system disk without wiping it? I'm guessing the installation starts at the first sector, and blocks the ability to use boot sect (I've tried, and it fails saying it can't install on this disk).


I have read that the PE loader is responsible for loading executable images from disk. When and where is the control flow exactly transferred to the loader? The PE format is well documented but there seems to be a little info regarding the functioning of the loader itself.


The PE loader is exposed by a set of user APIs in kernel32.dll, under the CreateProcess family. There are different APIs for doing different things, e.g. running a process under an alternative security context.






The tricky part with your question is that the "loader" isn't really something that gets control flow. The instant you call CreateProcess, you're technically running the loader. However, the kernel part of the loader begins when ntdll!NtCreateUserProcess transitions into kernel-mode. If we're really strict about it, we might say that the first part of the loader is PspAllocateProcess, since that's what allocates the initial structures.


In the book Mastering Malware Analysis: The complete malware analyst's guide to combating malicious software, APT, cybercrime, and IoT attacks [Alexey Kleymenov, Amr Thabet], there're 2 sections in chapter 2 called "Process loading step by step" and "PE file loading step by step" which document how the Windows PE loader is loaded and how it works.


I know from past the major problem was when I removed Ubuntu, I either still got into the GRUB booting menu, or I couldn't boot at all, and had to format HDD and start over. Now I found an article practically saying the Windows loader should be back upon deleting Linux partition, so I want to make sure:


If I have Windows and Ubuntu dualboot, and I want to get back to Windows booting quickly itself without choosing from any booting menu, is it enough to just delete the Ubuntu partition? Will the Windows loader override GRUB?


Note: Irrespective of which mode you install in, if you simply delete the Ubuntu partition, it won't make the Windows bootloader default automatically. You have to do it once, manually.


You'll most likely end up in a GRUB command line prompt on the next boot, from where you'll have to boot to Windows and delete the GRUB EFI Firmware entry or change the order to put the Windows bootloader in the first place.

Here is a similar question that can help in this case.


Manually delete the GRUB EFI boot entry and/or set the Windows bootloader to the first position before you get rid of Ubuntu.

This answer to a similar question explains the process for deleting it in Windows.


I am using Manjaro with Cinnamon DE.

I have installed wine, so I can run windows programs.

With right click on the exe the program starts and run well.

There is a setting on this program to start at double-clock on that with Wine windows program loader.

How start the program with command line options?

Thanks


Hi j8a ,

I know I can run the program by right click on that. That is OK, but after the right click how can i enter the command line options?

I tried to run from terminal, but the program or the wine or something else immediatly crashed.

But with simple right click or simple double click works well.

So the question, how can use the Wine windows program loader from terminal?

Regards


I've asked how this can happen, when was the last update etc because something caused my K30 to go into Bootloader mode randomly and is now useless. Corsair themselves still sell this Keyboard directly through Amazon.


I was wondering why the Vulkan SDK doesn't just come with a binary on Windows, like it supposedly does on Mac/Linux. Why leave it up to the GPU vendor to provide if the loader is GPU agnostic to begin with. Ultimately, this method seems like it can only be more complicated on systems with multiple GPUs. Basically, I'm just looking for anyone to clarify the justification for doing things this way, since I can't find any details online. Thanks!


The new versions of dataloader seems to have additional requirements. I have seen some other that also encounter this error.Suggest instead wasting your time, simply install old version of the productv38 is steady and I'm working with this years without problems.


Everything worked except I forgot that I had been using the free version of EasyBCD to manage the Windows Boot loader entries. Originally when I set this up with Ubuntu 14, I believe I did not install Grub. I just used easy BCD. But now I have a machine that boots into Grub and then if I select Windows it boots into the Windows Boot loader asking me to choose Windows or Lubuntu.


Hey! You just need to re install windows bootmgr. It will delete grub during the process. To do that you will need a windows 7 installation usb or cd. Once you have an installation usb or cd ready follow following steps:


The next part gets a lot easier if you set your systemd-boot resolution to max with adding

console-mode max to your esp/loader/loader.conf but this step is optional. (Adding that will also enable the OEM boot logo for Windows)


After some trial and error I found the solution: cp /boot/EFI/systemd/systemd-bootx64.efi /boot/EFI/Microsoft/Boot/bootmgfw.efi

So, whatever distribution, whatever bootloader I use, this works (of course just with the correct path to the linux-bootloader .efi-file). As soon as the linux-bootloader .efi-file is disguised as Microsoft bootmgfw.efi everything is working.


Due to a GPU upgrade, today I reinstalled my Linux (Pop_!OS with nvidia driver) on my dual boot configuration alongside Windows 10. It is a GPT style NVMe disk.Doing so, I think that I accidentally formatted my windows bootloader partition. I guess I have reinstalled Linux in UEFI mode alongside Legacy Windows Installation. Will I be able to fix my dilemma somehow?Right now I am pretty messed and I would like to repair/rebuild a functioning Bootloader, which recognized my Linux Distro and Windows 10.


I have a Dell laptop with two drives - I have the Windows 10 on SSD and I want to install Ubuntu on HDD. Windows has its own Boot Loader on an ESP in the SSD.

Can you please explain in detail how I should configure the partitions for the ubuntu boot loader in UEFI secure boot?


In addition to that, how should I add Arch to the Windows Bootloader, as I'm unsure of what I need to do with bcdedit, or if EasyBCD 2.2's compatibility with EFI is confirmed. Also, if anyone has any good program recommendations in lieu of EasyBCD, it would be appreciated.


NTLDR (abbreviation of NT loader) is the boot loader for all releases of Windows NT operating system from 1993 with the release of Windows NT 3.1 up until Windows XP and Windows Server 2003. From Windows Vista onwards it was replaced by the BOOTMGR bootloader. NTLDR is typically run from the primary storage device, but it can also run from portable storage devices such as a CD-ROM, USB flash drive, or floppy disk. NTLDR can also load a non NT-based operating system given the appropriate boot sector in a file.
