[ SOLVED ] No grub boot screen on startup

[rokytnji]

Maybe running os-prober will pick it up but I cannot swear to it.

Code: [Select]

sudo update-grub
See. The biggest problem with my response is. I do not dual boot with Windows.
My Linux Laptops are Linux only.

My one Windows laptop for tuning motorcycles is Windows only.
I have no use for dual boot like other members have.
So my responses are limited.

Hey guys, just wanted you to know that I found the reason for not having a boot menu screen at startup.
I installed "Grub Customizer" so I could take a look at the grub config.

It turns out that it was configured for no menu, and a boot delay of 0 seconds. Meaning that there would be no boot menu and it would boot directly into the default OS.

I enabled  the boot menu option and put a delay of 3 seconds.
Lo and behold, the boot menu now shows. LL is the only item on there at present.
I'm still trying to figure out how to add windows to the menu. If anyone has any input I'd be appreciative. My Win10 install is on another internal SSD. In Gparted the boot partition shows only as boot, no eufi. Not sure why it doesn't show in grub2.

But anyway, the grub menu issue is resolved.

Thanks
Len

Hello!

If you're booting Windows 10 in UEFI mode, and LL in legacy mode, to use the GRUB bootloader, you will need to convert LL to boot in UEFI mode - which, basically, adds in the UEFI version of GRUB from an Ubuntu LiveCD. All this and the link to the YouTube video  Is mentioned in the forums somewhere; you can either search here or Google for the video on YouTube. Or, as Rok suggests, you can just switch back and forth in the BIOS instead...

Anyone have any inout on this please?

As I stated, I can boot LL but there is no grub splash scree, it just goes directly to LL, even thhough I have Windows 10 on another partition.

When I want to boot either OS, I have to enter the bios boot options and select the appropriate OS.

Is there a way to enable a boot grub splash screem so I can select either OS at startup?

Thanks!

Since your able to boot into linuxlite, boot into it and run these commands and steps. But let me start with a warning, your messing with your bootmanager. And it's dangerous at any stage to manually edit these things. Only edit What I mention, and be careful. Backup any data, both for linux and your windows install.

Fire up a terminal and type this, entering your sudo password ofc when prompted.

Code: [Select]

sudo leafpad /etc/default/grub
At this point we're going to make grub give a timer for the grub menu. So you can just let it boot to it's default, selecting an os only when you need to. Find the line GROUB_HIDDEN_TIMEOUT and change it to =10. This is in seconds and you can adjust to what you want. Maybe =5 for a 5 sceond timer.

Code: [Select]

GRUB_HIDDEN_TIMEOUT=10
Next you wanna stop grub from being hidden, basicly you just change the option from true to false. 

Code: [Select]

GRUB_HIDDEN_TIMEOUT_QUIET=false
These are the ONLY two options you needed to edit. Save the file and exit.

Now run:

Code: [Select]

sudo update-grub
That command updates grub to use your config changes, its important to run that command when any changes to grub is made.

Finally, your presented with a countdown now when booting, to select/view the grub menu simply press the shift key at boot. This should be all you need assuming grub and all the autmated tools have done their job.

@Len I'm extremely busy with LL development at the moment so can't answer peoples questions as much as before. Best just to address the Forum folk generally, than someone specific, as you may get disappointed by the delay. Cheers

UEFI, 2 drives, and Windows 10 is hard core hacking. Not for the novice.
Switching drives in bios is easier IMO.


You might want to consider running a persistent sd card install of linux lite on that laptop.
Something I was doing when I first joined this forum.

Hi,

Sorry I can't help you,
Sometimes the knowledgeable folks on this may not visit everyday, so you have to be a little patient.
It may help though if you attach a System Report, so people can see exactly what your system is.

Hello again Jerry

I installed LL on a machine that also has windows 10 on it.
They are on separate SSD's.
Windows was already installed and then I installed LL from USB.
LL did not recognize any other OS's and so I picked "something else" from the install drive selection.
I had already formatted the drive with a boot partition, a home partition, and a swap partition.
I designated them as such for the install with grub to install at the first boot partition.
All went well, but I am not getting a grub screen at startup. I have to enter the bios boot screen and select which system to boot.
The windows drive is set as default in the bios.

I then re-installed. This time LL found windows and so I selected "erase the drive" as my install option.
LL installed and designated the windows SSD as the location for grub.
Finished the install, but this time there is no way to boot LL at all. No selection in the bios boot screen will activate LL.
Windows was untouched and boots as normal.

I installed a 3rd time, and LL did not find windows. So, I went through the first scenario again. And again, I can boot either OS but only by getting into the bios boot selector and designating the appropriate boot option.

When I have installed other linux distros on the same machine, if I select "erase the drive", it automatically handles the grub install properly, and when I reboot I have a grub screen to select either windows or linux. Not so with LL.

So, I do want to keep running LL, but I would like to be able to simplify the boot selection at startup.

Is there a way to correct this?

Thanks and I do love Linux Lite.
