Bootloader installation failed while installation

I needed to install bootloader on sda7 but while making my partitions i set it to sda so now i am trying to change it it is not working nor is it getting cancelled

Boot from LiveUSB
In terminal run

sudo mount /dev/sda7 /mnt

sudo grub-install --root-directory=/mnt /dev/sda7

Unmount when complete

sudo umount /mnt

Boot up and test.

But how do i cancel this first

You can just close that out and boot into the LiveUSB. Sounds ugly, I know.

It isn't closing

I mean... Close the system out. It's ugly but you have no other choice.
Shut down and boot into the LiveUSB.

ok i will try it now

what can i doo

There should be a Space between /mnt and /dev/sda7


Are you installing on nVME or eMMC SSD?

a 500gb hdd
i was using windows now wanted to shift to linux with the files

can i run boot-repair in the terminal?

What does

sudo os-prober

Which devince has your bootloader?

sudo grub-mkdevicemap

Typo: gurb - grub

Nothing happened

How about:

sudo exec grub-mkconfig -o /boot/grub/grub.cfg

Please mind the spacing and ensure no typos.

Also, I see Windows OS is listed. If you boot up Windows, is Dynamic Partitioning enabled? That should be set to Simple, not Dynamic.

The output of the code shows
sudo: exec: command not found

It was dynamic partitions in windows

Now I'm not able to boot windows too

Boot into live usb, what n send pic of "disks" app

How was it partitioned?
