I'm an old guy that continue to get myself into situations were I have risen to a incompetence.
What I have done is dual mounted Zorin 17.1 with POP!. It has been working great and now I want to remove POP!
I have opened Disk in Zorin and see this:
I have also clicked on the Volumes and can see how they can be deleted.
What I don't know is what Volumes are POP! which I want to remove and which are Zorin.
Can you point me in the right direction? Keep in mind that I don't know what I'm doing and don't speak "Geek Speak".
You see on Your Partition Table ''Filesystem Partition 3 155GB'' and ''Filesystem Partition 5 85GB''.
These 2 are Your Systems - Zorin and Pop. To know what is what, You should remember how many Disk Space You gave Pop OS. That would be a good first Step.
Don't delete directly. Only remember for that to know which Partition can be deleted.
Oh, it is a Laptop from System76. Okay. Because of Your Words:
I thought it is a normal Machine with Zorin on it and then You had installed Pop OS to that. Okay, when You have installed Zorin to this, You should remember how many Disk Space You gave it. Or You open Nautilus in Zorin and there You got to ''Other Places'' on the left Side on the last Position. Click on it and You get an Overview.
I wrote that for the Reason that You not accidentially delete the wrong Partition and You lose Your Data. And only deleting the Partition isn't enough. You have to delete the EFI Entry for Pop OS, too. When You don't do it, You could get Issues when You start Your System. That is the Reason why I want to make it carefully.
I didn't give Zorin any spaces. I installed the OS from a usb and by some magic it got installed on the disk.
I appreciate you trying to help but I think you missed the part where I said I was an old man that didn't know what he was doing. You are telling my things that are way beyond my current understanding. I guess I'll leave the system as a dual boot until I can gather some more understanding or die whichever comes first.
Thank you very much.
I understood that. That is the Reason why I want to make that carefully Step by Step. And that is the Reason why I wrote that you not should delete a Partition directly before it is clarified which is the right Partition.
At some Point You have to because without that Zorin couldn't be installed. Did You used maybe a Youtube Video or Instructions to install Zorin?
"You have to delete the EFI Entry for Zorin, too. When You don't do it, You could get Issues when You start Your System."
I have deleted POP! OS for partition 3. Can still boot up to Zorin but in the booting process I still see the option to select POP!
This is what efibootmgr shows me:
BootCurrent: 0004
Timeout: 2 seconds
BootOrder: 0004,0000,0002,0001
Boot0000* UiApp
Boot0001* WD Blue SN570 250GB
Boot0002* UiApp
Boot0004* ubuntu
The Current boot 0004 is Zorin.
I was reasonable sure that 0001 was POP! and using
sudo efibootmgr -b 0001 -B I tried to remove it but that did not work.
I can live with what I now have but would like to clean up the booting process. Can you help me more to do that?
You have been very patient with me and I thank you for that!
should also work to remove the Bootloader from the efi partition. Note that this only removes the bootloader. It does not remove the partition that contains that O.S. or the O.S. itself.
Please don't be irritated by the Language. My system is in german. It is the black marked Option at the Bottom. Then you get at the left Side an Overview. Take there the first One:
That should be Your current using Zorin System. When You have clicked on it, go to boot and then to efi and then You have to type in (2 times) Your Password because this Folder is secured. Then You should find something like this:
Yes, thank You for the Screenshot. The Pop OS Folder is what You have to delete. After You have deleted the Folder open the Terminal and type there sudo update-grub to update the GRUB Menu.
Yes, I should have asked that before. Do You have installed nautilus-admin? This is a little Extension for the file Manager so You can run them as an Administrator (that means with higher Permissions). To check if it is installed, type in the Terminal apt list nautilus-admin and when there is nothing found or the Package is found and there doesn't stand in square Brackets [installed] then it isn't installed
If You don't have it, open the Terminal and type sudo apt install nautilus-admin
This Command will install the Package and then You should be able to get in the Folder with typing in Your Password.
That advice was a WINNER! That eliminated the boot up page that showed me options for Zorin or POP! which is just what I wanted.
I did the `sudo apt install nautilus-admin' and it was installed per the Terminal but I don't find it anyplace. That is not important; I now know how to get into /boot/EFI thanks to you.
One additional problem - minor problem. When I use the Terminal to change the timeout I enter 'sudo efibootmgr -t 0' and the I check it by entering efibootmgr and it shows that the timeout is 0. I reboot and check again and the timeout is back to 2, where it was before. What am I doing wrong? What can I do to make the timeout 0?
I thank you so very much for your help; you have been GREAT! I submitted my original problem to GNOME and have yet to receive a reply.
This isn't an extra Program. So, You can't find it. It is an Addition for Nautilus; it is now built-in in Nautilus as a Function.
For the Timeout:
Open the Terminal and type sudo nano /etc/default/grub
With this Command we will change the GRUB Configuration File to set the Timeout to 0 like You want. So, type the Command and You will see this:
The important Point is in the white Block. You see there the red marked Place. There You type in the 0. Then You press on Your Keyboard ctrl+o to save the Change, Enter to confirm and ctrl+x to exit. When You then back to the normal Terminal Overview, You have to type in the Command sudo update-grub to let refresh the Configuration File and let the Changes work. Please don't forget this! Without it, it will not work.
That changed the Grub Timeout but the efibootmgr still shows a Timeout of 2 seconds. This is not an issue and we can consider this problem solved.
I thank you again for all the time that you have devoted to fixing my problems. Perhaps I have also learned something along the way. HA
This was a reply from System 76 about why efibootmsg is not making the changes I entered.
" Unfortunately, the current edk2 platform does not use the Timeout variable. Looks like Timeout is useless in edk2 because it overwrites it with PcdPlatformBootTimeOut on every boot.
I've talked to QA about this, and they might think about fixing this in the future."
As I said this is not an issue at this time. I can live with a 4-6 second boot time, which is what I'm getting.
