Windows not loading after grub install

Safeway44 · 04-05-2017, 07:34 AM

From the Grub menu Windows 8 does not load after I select it I get an error
File:\Boot\BCD
Status: 0xc000000e

When I change the BIOS to UEFI from legacy Windows works
but then Kali is not accessible.I had to install Kali under Legacy because under UEFI the CD didn't do its thing, other than the computer brand's logo on the screen glaring.

During install Grub was placed in MBR. As this is a UEFI system is MBR even required? I don't have a spare USB lying around so if the solution can be utilizing the CD that work be ideal.CD is tested and working.

Kali iso is a recent download and it's meant to be UEFI friendly. Kali is loading fine. Thanks

As far as I know, modern versions of Windows will not boot from a GPT disk with a bios. You have to use uefi. And, as you probably know, it is dangerous to keep switching modes because sooner or later you are going to use the wrong one. However, it is possible to convert a bios install to uefi. Basically you have to reinstall grub in uefi mode so that it goes onto your efi system partition. You can do that, using your installation disc.
Here's something I found on a Ubuntu site:

Code:

sudo mount /dev/sda1 /mnt # Mount the root filesystem in /mnt
sudo mkdir /mnt/boot/efi # Create a directory to mount the ESP in
sudo mount /dev/sda3 /mnt/boot/efi # Mount the ESP
sudo grub-install --root-directory=/mnt /dev/sda # Run the grub install

Basically you boot from the CD, mount your normal root partition, mount the efi system partition on the root partition's /boot/efi directory and then install grub there.

What is Kali? Can you tell us more about what it is?

Once a new OS is installed, it is sometimes necessary to run

Code:

update-grub

from the terminal.
So boot your linux distro, run 'update grub' and see if this makes a difference.

Making changes on BIOS to UEFI is not related to your problem.
All linux distros should now be 'UEFI-friendly'.

What is Kali?

It's an operating system designed specifically and only for penetration testing/computer forensics and is basically meant for experts. Obviously, it can be used by people wishing to learn/study computer forensics and is absolutely not recommended as a standard Desktop distribution as explained at their site below.

http://docs.kali.org/introduction/sh...use-kali-linux

Mixing MBR and UEFI as mentioned above is the problem and the simplest solution to the problem the OP has would be to install Kali on a flash drive and select that drive on boot when he wants to try to learn penetration testing.

If you are using UEFI, you should not have any boot code in the MBR and mixing the two is going to lead to boot problems. If you can boot either by making a change in the BIOS, that's the best you can do if you can't get Kali to install uefi. I'd suggest taking a close look at the Kali documentation on installing UEFI.

sounds like you did a different boot method for each one, I'd suggest installing Linux by the same means windows boots. kiss is involved here, get their greatest hits album on apple cares today.

but that gpt thing well then....

Agreed.

I recall placing Grub in MBR when prompted during install, I should have said no. How do I remove it from MBR?

No thanks, I just want to Gpart all night and everyday

At this stage, you'll have to boot the CD in bios mode. The point is to change that for the future.

Yes. These are console commands.

I have no idea. I've never used Kali. And if you know so little about Linux as to ask these questions, you should not be using Kali either. It's really not a good distro for learning.

Quote:

Definitely not! gparted is a partitioning tool. There's probably nothing wrong with your partitioning scheme. You just need to install grub where the uefi expects to find bootloader code, i.e. in the efi system partition.

I started with root@(none)

Do I need to be online (connected) to install? Can it be done through Grub prompt too?

Are you logging in remotely? That "connection refused" thing usually occurs when people use ssh.

Make sure you are using the right device name for the partition. It probably isn't sda3 on your system. That extract I gave you was just an example. Running fdisk -l will give you a list of the partitions on your own hard drive together with their types. The one that is down as an efi system partition is the one you need to mount.

You can check if the efi system partition actually has mounted by subsequently using the mount command without any arguments.

No I am not logging in remotely. Accessing a computer that's sitting on my desk in front of me.

I ran fdisk and was able to see a list of partitions and one labelled EFI.

However when I tried fdisk l on a virtualbox version of Kali I didn't, instead I got: Welcome to fdisk (util-linux 2.29.1)
Changes will remain in memory only, until you decide to write them to disk. Be careful before using the write command.

fdisk: cannot open 1: no such file or directory

Is this what you mean by no arguments?:
sudo mount

That should be "-l" for "list", not a 1

Exactly, except that you don't need sudo when you use mount this way. Listing mounted partitions is a job anyone is allowed to do. The term "arguments" always refers to strings that follow a command. They provide extra information for the program.

You know, someone who is so much a beginner as you are shouldn't be using Kali at all.
