So I decided to replace the partition with an already installed Manjaro KDE, which when I still had it, GRUB was working fine. But now after replacing it with Manjaro GNOME (Dual-boot with Windows 10) I get this:
BootDevice Not Found
Please install an operating system on your hard disk
Hard Disk - (3F0)
F2 System DiagnosticsWhen installing GNOME, one of the options was to replace an existing partition - what I did.
replace ?
Can you share the screenshot by running the calamares installer again?
Also when you run the os from USB drive can you share the output of the following command
lsblkWould be nice to have more information, since it could be true, that you deleted the whole HDD:
sudo parted -l
This message:
comes from the UEFI, so i guess it it did not find the EFI Partition or the MBR. Otherwise, there would be a grub emergency shell.

I guess then this the root / partition:
and this the /home partition:
Since /boot is on the root partition, you need to deflag the /home partition and flag the root partition with “boot”.
I don’t know how to do this. Do I do this in konsole/Terminal?
No, that can be done in a live session with gparted. I guess you have to reinstall grub also, maybe i am wrong.
I did what you said so let’s see!
It did not work.
Could you post the content of the partitions?
sudo su
mkdir -p /mnt/sda6 && mount /dev/sda6 /mnt/sda6 && ls /mnt/sda6
mkdir -p /mnt/sda7 && mount /dev/sda7 /mnt/sda6 && ls /mnt/sda7
I guess you have to reinstall grub.
Chroot first:

Then install grub:

So do this on the live USB installation?
Also, I did manual partitioning and deleted that partion, here is what I’m left with:
Model: ATA ST1000LM048-2E71 (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/4096B

5 965GB 999GB 34.0GB logical linux-swap(v1)
4 999GB 1000GB 841MB primary ntfsThen better formating /dev/sda6 and install Manjaro Gnome again. Keep sure the boot flag is set. Use manual partitioning… and set /dev/sda6 as root.
There are two options for installing the bootloader: 1st is the Master Boot Record (/dev/sda) or System Partion (/). Which do I do?
First one… it should write to the MBR > Master Boot Record.
Ok, I’ve already done it with the boot flag set to sda6 while also installing boot loader to MBR. Still says no operating system when I boot my hard drive.
