What is Reddit's opinion of Visual BCD Editor?

From 3.5 billion Reddit comments

To make it easy, I would download this tool and run the "Repair MBR & Boot Records". This will remove the GRUB boot loader. Then you can remove the partitions of Linux on something like Disk Management.

It tends to not be easy. Like, at all, and is an absolute crap shoot for success. I've had mixed results with /bootrec fixboot and /bootrec fixmbr when using CMD from Windows boot media, your mileage may vary.

Here's a different guide - https://www.boyans.net/RepairWindows/repair-windows-boot.html

My only other advice if you still can't get it would be to make bootable Linux media, mount the drive, and back up anything you can't afford to lose, then do a clean install.

>I tried using this Dual Boot Repair tool >https://www.boyans.net/DualBootRepair.html to automatically >fix it, nope didn't work either.

Use version of the tool for Windows 10 - https://www.boyans.net/dual-boot-repair-windows-10.html

If automatic repair cannot fix then do manual steps when booted in Windows 10:

1. use bootsect to rewrite MBR and partition boot records

2. use bcdboot to rewrite BCD.

Check that disk structure is intact. Check every partition for errors. Check that active partition is present and has at least 50 MB free.

Use dism to fix component store.

Then run sfc /scannow.

Windows 10 boot repair. Generally speaking, boot repair utilities don't mess with other operating systems. If you fix the Windows 10 bootloader, you'll lose the Grub bootloader.

Boot repair for GRUB, on the other hand, is usually very good about finding other working Operating systems to choose from (normally). Best bet is using a windows boot disk and running a repair option to get windows 10 booting. Then run the boot repair for Linux. If you're still in this conundrum, nothing appears to be fatally broken, just bootloader confusion - it can normally be fixed.

Make a USB with the Windows 10 ISO in it, go into BIOS, and boot into the USB, and try to repair Windows from that. See here: https://www.ifixit.com/Guide/How+to+Create+a+USB+boot+drive+for+Windows+10/89181

If I had to guess it sounds EAC doesn't like something in your windows boot options.

Read the info carefully, this should fix your issue but you could also screw up your machine if you get it wrong.

If you want to wipe clean and start off fresh you can download the Windows Media Creation tool found here: https://support.microsoft.com/en-ca/help/15088/windows-create-installation-media

Create your installation media, boot your system from the newly created disk. Select to install Windows, delete all partitions on your hard, then let the installation wizard create the necessary partitions and install the OS. This will effectively delete and overwrite all data that was on your disk.

Now onto why the dual boot setup sort of messed up your system. Windows will look for a file on a certain area of your disk called a bootrec. Probably stands for boot record, I forget. When you install another OS a new bootloader becomes the default.

You can open up a command prompt and repair your bootrec using built-in windows tools if you know what drive letter your OS is installed on. This way might be a bit frustrating and complicating if you've never worked at the command line. There's a guide here: https://neosmart.net/wiki/bootrec/

The alternative to using the command line is using a graphical interface with software like Visual BCD Edit - if you can get into your OS. You can find a guide here: https://www.boyans.net

Does the drive appear in BIOS? If the motherboard can't see the drive then all the ports are bad.

Ensure that the boot order is correct in BIOS.

If it sees it in BIOS and boot order is correct, you can attempt rescuing the partition. It is a little risky and there are no guarantees that it will work. If no one else has any ideas, you can try this as a last-ditch effort, but you could lose your files if it fails" You will need a CD/DVD/USB for Windows install. Link

What it looks like.

This is the message i'm getting when i try to do advanced repair. I didn't think it'd be encrypted, but is it?

Oh, drive letters assigned in a command prompt aren't persisted in Windows at all - they are just temporary things.

Re-execute:

• select disk #
• select partition #
• assign letter=s

To make it appear again.

Also, as stated, add the /v option, but also if it doesn't work, run Visual BCD Editor and take some screenshots so we can see what your BCD currently looks like.

We/you might even be able to use that tool to simplify this process - however I'm not exactly sure what all the commands do.

Keep in mind I'm not an expert on this stuff, I've dealt with some of this type of thing before, but I just noticed what appeared to be your problem from the initial post, and am now kinda just going with the flow.

I'm not sure how to view the set values from command prompt in windows 10. Used to be bcdedit /enum all in windows 7, but doesn't work in 10 under Admin prompt. https://www.boyans.net/ Found this handy utility while researching it though.

Hey, thanks for replying!

1) Compatibilty mode doesn't work

2) Doesn't work, but it did speed my computer up, so thanks

3) I'm on directX 11, alpha centauri is much older than that but I'll try it

4) I repaired my BCD with this tool https://www.boyans.net/dual-boot-repair-windows-10.html but I still couldn't use "bcdedit.exe /set {current} nx AlwaysOff" in the command prompt. I think I'll give this another shot tomorrow. Otherwise I'll just have to mash f8 when I boot my laptop for safe mode haha

It was MBR. Go to https://www.boyans.net/DualBootRepair.html and get that tool. In the tool, do the following:

Repair MBR & Boot Records

then

Repair BCD

Reboot. Easy once you figure it out.

Did you happen to install a os via dual boot? Or install a OS from one USB to another USB? If so use this tool: https://www.boyans.net/dual-boot-repair-windows-10.html If not have a look at this tool: https://www.boyans.net/ . I used the dual boot tool and after some button clicking I got rid of the grub boot loader and put the windows boot loader back

This may help:

Dual-boot Repair Windows 10 (8.1/8/7/Vista/XP)

For safety, I would create a Restore Point first. Just to be on the cautious side as I have never used it.
