Hi all, The installation done, working well, but a bit long time when I start the PC and I have that three option to select. How can I change that time? Many Thanks
usally the first bootup has the 3 options on screen usally after a few boots it will just show the zorin badge on screen and then boot
as pertaining to boot speed that will depend on what type of drive its booting from ata drive..sata ssd on nvme type these are listed slowest to fastest
Thank you wesoliv429
So I no have to do nothing? After a couple of restart that three option is gone and I no have to wait? Running from an NVME m2 so is fast, just during this selecting on the top of the screan going a line which is slow.
Thanks
You are referring to the Grub Menu. By default, Zorin OS sets this to "hidden."
However, if you dual boot, it will show, in order to give you a chance to select which operating system to boot. It is set to a timeout of Ten Seconds that it waits.
Are you dual booting?
I do not have dual boot.
I can choose this three option:
Zorin OS
Advanced option for Zorin OS
UEFI Firmware Settings
So during this time on the top of the screen going a white line from left to right which is delaying the boot.
Hi the default is 10 seconds. You can reduce this time by editing GRUB but I would not drop this to anything less than 5 seconds as (on the assumption the File System in use is Ext4) as journaling systems (similar to NTFS) should not have a speedy boot time as you could crash the system.
Follow this guide (which ironically is the reverse of what you want) and change the line with 10 to 5):
What is interesting is I use two different OS's that default to a 5 second timeout by default (Q4OS Plasma and PCLOS Debian Plasma).
He means the choose 1 of 3 options that shows up now and then for some reason on mine it took 3 logins( 3 days) for that to go away I do have mine set to just login tho My cat is unable to type my password.....lol

Yes, this is an Indicator. It shows the Time that You have to decide which Option You want choose before it starts the default Option.
Now, it depends if You want still have it but only shorter or if you want to get rid of it entirely. For both Options, you have to adjust a File. When in Zorin open the Terminal and type:
sudo nano /etc/default/grub
and then You can work on the Config File for the GRUB Menu. Important is here the white Textblock at the Beginning:
If You want get rid of the GRUB Menu Overview change the Lines 2 and 3 to that what You see on the Picture:
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
If You only want shorten the Timeframe, change only the Number in your existing Setup in the Line GRUB_TIMEOUT to 5 for Example. Then the Menu will appear for 5 Seconds.
When You have made Your Change/s press ctrl+o to save the Change, Enter to confirm and ctrl+x to exit. Back in the normal Terminal Overview type sudo update-grub to make the Changes affect. Don't forget that! Without that, it will not work.

I have the default grub, where the timeout is 0
What is your terminal output for
efibootmgr
BootCurrent: 0000
Timeout: 1 seconds
BootOrder: 0000,0001
Boot0000* Zorin OS HD(1,GPT,a0d0a03e-37bc-4d5c-872a-749d0be15943,0x800,0x100000)/File(\EFI\UBUNTU\SHIMX64.EFI)
Boot0001 neon VenHw(99e275e7-75a0-4b37-a2e6-c5385e6c00cb)
This is what you mean?
This shows that you have KDE Neon Bootloader - which is what is kicking the Grub Menu to appear in order to choose that OS.
If you have overwritten that OS and no longer use it, you can clean out that boot entry.
sudo efibootmgr -b 0001 -B

I did it now.
Updated the grub.
Restarted, but still there.
I don't know if this will be help.
So on this drive was a Win11 before. When I start to install the Zorin selected to erase and install Zorin. So not installed next to any other OS.
Windows is not showing a bootloader, at least. But Neon was.
We probably need to go one step further and remove the actual frile from EFI partition.
This requires knowing where your EFI partition is - can you Identify the drive?
lsblk
You should see /boot/efi listed for that drive ID
I will changed the grub to this.
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_RECORDFAIL_TIMEOUT=0
GRUB_DISTRIBUTOR=(. /etc/os-release; echo ${NAME:-Ubuntu})
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
Added to the gub which is highlited, and after the grub update and restart IS WORKING
Many thanks guys
