I have a quad boot system, and on my grub screen I have 2 entries for each option.

I read the forum post here about multiple entries. I tried this solution linked from a Gentoo forum, by adding OS-prober exclusions to the etc/ default /grub for each drive asides from the Garuda boot drive, ran update-grub, rebooted and it didn't make a difference. I noticed during the update-grub process that it found all of my 4 OS's 4 times each it seemed during the probing.

I tried rEFIned for a test, and it just looked gash - about 7 penguin Icons, a dull grey screen, a windows icon, and 3 Ubuntu Icons (I don't have Ubuntu installed anywhere) and also 3 sets of keys which didn't seem to do much and a helpful Info screen which told me not a great deal, so I think that's out of the question.

Does anyone have any suggestions?

FGD · 16 May 2022 17:24

If you could post the output of

bat /boot/grub/grub.cfg

we could probably see what generates the entries.

I am assuming the OSes don't write into the same grub.cfg. If they do, I personnaly cannot help much.

BluishHumility · 16 May 2022 17:29

You have to set up rEFInd the way you like it.

Regarding the many icons, rEFInd will identify pretty much anything that looks bootable and set up an icon for it in case that is the method you want to choose. You just have to identify the ones you actually want, then hit the “delete” key on the others and it takes them off the menu (it doesn’t actually delete anything, it just removes it from the menu).

As for the grey screen, most rEFInd enthusiasts will install a theme. A bunch of ideas are here: The rEFInd Boot Manager: Theming rEFInd

There are tons of other ones available on GitHub. Personally I’m partial to the “regular” theme: GitHub - bobafetthotmail/refind-theme-regular

norse · 16 May 2022 17:29

[bat error]: '/etc/boot/grub/grub.cfg': No such file or directory (os error 2)

norse · 16 May 2022 17:30

That does look nice - is there a manual online I can find how to use it?

FGD · 16 May 2022 17:30

Sorry I made a typo, it's /boot/grub/grub.cfg. loll But I think Bluehish's way is a better guess for now as you use reFIND.

norse · 16 May 2022 17:35

Sorry, please ignore, I see you included manuals.

BluishHumility · 16 May 2022 17:37

The answer to this question is “yes”, although I’m not sure if you mean rEFInd or the Regular theme.

The Regular theme doesn’t have much instruction needed: just install according to the GitHub page and it will ask you when you set it up what you want (dark or light theme, large or small icons).

Bear in mind, you will still get Tux icons for an OS that doesn’t have a .png in /boot/efi/EFI/refind/icons. You can add in a .png and name it os_nameofdistro.png where “nameofdistro” matches the grub distributor (for Garuda, name the file os_garuda.png).

If you mean is there a manual for rEFInd, the website is a massive and complex resource that covers all kinds of subjects related to rEFInd, and also bootloaders in general: The rEFInd Boot Manager

mrvictory · 16 May 2022 19:03

When I am dealing with more than 2 OS, I usually disable autodetection, which is disabling os-prober for GRUB and disabling scanning of internal partitions for rEFInd, then I add my own boot entries.
For rEFInd, I add a few entries like

Boot the default kernel and initramfs (if the distro has fixed kernel/initramfs names)
Boot to singleuser mode, boot the previous kernel, boot the regular kernel etc.
Load the GRUB of the distro

For GRUB

Load that distro's GRUB configuration with configfile command
Boot the default kernel/initramfs

I've been able to find a refind.config-sample file, but no refind.config file. Are they the same?

BluishHumility · 16 May 2022 19:31

There isn't one set up--if you want to use one, you can make it.

In most cases you do not even need to make a refind.conf--it depends on what you want to boot. If you want to use rEFInd as your boot loader and just boot from EFI stubs or whatever, you may need one.

Open up the -sample file and find a boot stanza similar to the OS you want to boot to, then delete the "disabled" line and add in whatever the details are for what you need to boot. When you exit the file, delete the "-sample" and viola--you have your refind.conf.

Getting the boot stanza correct is very tricky--I fumbled with it quite a bit setting up my first one. Read through the documentation on the website, and also the Arch Wiki page here to help get it right.

For my Garuda installations, I prefer to let rEFInd boot to grub--that way you can easily restore a snapshot or change to a different kernel if you like. I typically disable OS-prober as well to tidy up the grub menu (it's not needed if you are using rEFInd anyway). If you are booting to a bootloader (grub, or something else), you do not need to make a boot stanza in refind.conf.

For more than one Garuda OS I use the simple /boot/grub/custom.cfg

Refind is clearly a very good piece of software, with a manual that has not been written well ..after about 2 days of scrawling through various forums, making changes and testing themes, I still have an Ubuntu symbol for mint after trying tune2fs and sgdisk. I have not found a clear answer on how I modify the positions of order in the refind menu, and do not know what to modify in order to get rid of redundant icons or duplicates within the menu.

Is there a way of just modifying the garuda grub to ignoring the duplicates? I think it would be easier this way.

norse · 18 May 2022 15:36

Woohooo...managed to do it - don't know why I just didn't try modifying the grub config to begin with - now I just have a UEFI boot duplicate.

A roller coaster of emotions, for what was quite frankly a trivial issue....at least I picked up some things along the way.

FGD · 18 May 2022 17:11

What file did you modify?
If it's /boot/grub/grub.cfg, that one is a no-go as it will reset next time you run grub-update.

norse · 18 May 2022 19:43

Yes, grub.cfg was the one I changed.
Nevermind, it takes a minute to make the change when it reverts back.
TBH, It's taken me 500 times that to get nowhere with rEFInd.
Maybe on the 500th time I have to do it, I'll give rEFInd another go.

mrvictory · 19 May 2022 18:47

If you have installed many distros but didn't clean up their bootloader files (usually reside in /boot/efi/EFI/ distro-name/grubx64.efi) rEFInd may be showing them as Tux icons.
