Re: Windows Loader 2013 V 3.8 Activation For All Windows
Alueche Elswick
I have Windows 8 pre-installed, and then I installed GRUB with Ubuntu. Ubuntu is not my thing, so now I want to remove it along with GRUB. From what I have learned, with UEFI, GRUB does not overwrite the windows bootloader in the EFI partition and is stored elsewhere. How would I remove GRUB and make my PC use the Windows bootloader instead? It should be noted that I created a separate /boot partition when installing Ubuntu.
Enter powershell into the windows search of the start menu. Look for a blue icon with the label "Windows PowerShell", right click on the that and select "Run as Administrator" within the context menu.
To Mount the EFI System Partition on the given drive use the mountvol command by using the /S parameter. You can chose any free drive letter you want. For example "S".
You can restore the Windows bootloader with a Windows 8/8.1 DVD. These instructions are inspired by Manindra Mehra's answer, but I expanded it with full working details (verified with a Windows 8.1 DVD).
With UEFI you have both a Windows folder & an Ubuntu folder in the efi partition. the UEFI reads the efi entries and adds them to its own NVRAM to remember them. You have to remove ubuntu folder from efi partition first or UEFI will re-add it. Then you have to remove UEFI entry from UEFI.
You should have these folders in the efi partition. Delete only the ubuntu folder. Live installer should show folders. And if only Windows you have to mount from inside Windows the efi partition as it is not normally mounted.
3: If you've done everything right up to this point you should see (depending on your computer) your splash screen for a second and then it will turn into an error screen saying that there was an error with the boot. ("Winload.exe is missing or corrupted" most likly).
For system with GPT partition table, the method provided by @Ganesh Kondal won't work. Using bootsect /nt60 C: /mbr will show that it worked while it really doesn't. Using bootrec /fixmbr will lead to error that "the system cannot find the file specified". If any of the above situation applies, do the following (Using Windows 10 as an example):
I have followed the instructions of the 2nd answer on this thread but after that my pc was stuck in a boot loop. Running the commandbcdedit /set bootmgr path \EFI\Microsoft\Boot\bootmgfw.efi fixed it for me since my Windows Boot Manager path was pointing to grub.
Anyways, I installed Debian on the C: drive in a separate partition, and installed grub. When I restarted the PC, it went straight into Windows 10 without launching grub. I did several google searches and ended up trying this, but this method did not work and yet again, my PC booted straight into Windows. I then tried this, which also did not work. I then tried directly installing reFIND through debian after booting into debian with a usb flash drive of refine to try to see if I could use refind as a substitute for Grub, but that also did nothing.
Please check your BIOS settings. I faced exact same issue on my HP Laptop which goes directly into Windows 10 bypassing the linux boot options. My issue was resolved by enabling legacy mode and disable secure boot option. Please check similar options in your BIOS too.
If you installed Debian and grub correctly, then all you need to do to be able to use them, is change your boot order in BIOS/UEFI or use the manufacturer dependent key during boot to select the boot device interactively - generally something like F11 or F12 or such. That should list your hard-drives and the bootable partitions.
I went through all of these steps however windows kept reenabling / booting first. I finally fixed it by enabling secure boot, which then allowed me to select my own "trusted" efi file in my bios (I selected grub). This then appeared in my boot order which I then put to the top and then turned off secure boot. Grub now loads first every time.This was on an acer with UEFI, GPT drives trying to dual boot Parrot OS and Win 10.
I was also facing the same issues, I have the hp envy 15-DR1XXX and I found out that the os boot manager from the list of boot devices was prioritizing the windows boot manager before the Linux one "fedora workstation". This is what I did.
Once in the Set UEFI BIOS boot entries dialog (2nd pic in tutorial) either move your grub bootloader to the top of the list, or if Windows deleted it just add a new entry, go, navigate to the EFI partition, and then the grub folder and select the grub file. Click 'Save entry' and move it to the top of the list.
If not sure how to, ....boot an OS like PuppyLinux(It's like 250 M.B.) and install from there, the process is graphical and easy . After installing GRUB from Puppy Linux........It will boot a grub at the beggining and you can see if Debian is there or not.......If it's not on the list then it isn't installed properly.....Reinstall it if it isn't installed properly
I want to know does windows 10 come with any bootloader so that I can boot from Linux using that boot loader? I have made a system rescue drive in case something goes wrong. Also, I know that if in UEFI or EFI bios Fast boot or secured boot option is ticked on then I cannot boot from Debian.
If you turn off secure boot you will Not have malware on your system, Not necessarily. if you use an updated Window 10 version and the Windows Defender (aka Microsoft Defender), you will be fine, it has very advanced features and protections that will not let malware come in.
After installing Fedora 34 KDE I have no access to the Windows 10 installation. (I also have no access to a previous Solus installation, but that problem had preceded the installation of Fedora. I have posted a separate topic on that here).
Here I am interested in restoring access from Fedora boot loader to my Windows 10 installation. (I had a Linux Mint in place of Fedora, and Mint had access to Windows but not to Solus. I have thought that replacing Mint with Fedora would fix the problem: it did not, it added a new one.)
I would like to be able to keep Fedora (remove other Linux, namely Solus) but I want a dual-boot with Windows 10. I think a solution would be to install Kubuntu in place of Fedora - I think that would provide access to at least Windows. But I want to give it a try here.
thanks a lot! getting closer and closer The Grub menu appears when I boot Fedora in Bios but if I turn on the laptop it will start windows directly. Is it something I need to configure in Windows so it recognizes a dual boot?
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 @ZaeNae ,
I do not know much about Cinnamon, but under settings you can surely find the mouse and touchpad icon to solve the double-click problem. I wonder whether is an executable MS file, in that case with a right clik on the program and then selecting Open with Wine may be enough.
The other answer depends whether you have installed the program or not.
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?

I have been trying to remove the Windows Bootloader or at least set it to be the last thing in the list of UEFI loaders to try via the Acer BIOS. Nothing sticks. Every time I reboot, no matter which bootloader I have set, it will just reset to using the Windows Bootloader and try to load something that isn't there. I've removed the Windows and the recovery partitions since I don't need them.
I also installed rEFInd and it sets itself as default boot manager at the end of installation. However, as soon as I reboot, something in the Acer BIOS (I guess?) is taking over control again and forcing the Windows Bootloader entry to first place.
I solved it! I had to switch Secure Boot on so that I could get to the option "Select an UEFI file as trusted for executing" (otherwise it would be grayed out). Then I navigated to the rEFInd bootloader and Debian's grubx64. I added both, then switched OFF Secure Boot. For some reason they still stayed in the boot priority list and I could now move them up.
There might still be bits of the Microsoft loader left, but I don't care because now the correct loader gets called first. Wheee! The BIOS version is 1.08 and I would like to install 1.13 anyway. It seems that only works with Windows, though, the BIOS can't upgrade itself from inside the BIOS, huh?
At least the parts of the bootloader that I could get to are gone, I deleted the recover partition at the start of the disk (it was sda1 when I looked at it) and the larger one at the end (it was sda7). Then I moved the Microsoft directory away from EFI/Microsoft so it can't be found. I'm not sure what piece of the BIOS or the UEFI system is still pointing at this bootloader, but I'd like it to point somewhere else
Edit: For some reason I can't find the boot list that lists valid EFI loaders in the BIOS anymore. I can find the boot priority list, but there I can only say that the built-in SSD is in number 1. I can't select which of the 3 loaders to use (I'm assuming the BIOS sees 3 because it keeps wanting to boot the Microsoft loader that isn't there anymore).
