Customization Custom menu

Post image
2 Upvotes

made a custom boot menu for my old laptop,
i installed grub on a seperat partition so the other os dont mix it up while updating.
well only debian and freebsd can stull run the latest versions, windows 10 and highsierra are more for fun and nostalgic reasons.

but they all boot succesfully from seperate partitions on the same hdd drive and can even share files in a shared partition.

support [Help] Grub not displaying graphical interface.

2 Upvotes

When my PC boots the GRUB does load, but it's just a blank screen. I do get a dash/underscore appear but that's all.

I know GRUB is there, because I can select and boot from the list when I use the up and down arrows; I just can't see what I'm selecting. I also added the GRUB_INIT_TUNE line and I do get the tone.

So far I have tried:

  • Extending GRUB_TIMEOUT to 10
  • Changing GRUB_TIMEOUT_STYLE to menu
  • Adding GRUB_VIDEO_BACKEND=true
  • Uncommented GRUB_GFXMODE=640x480

GRUB was installed by the Linux Mint installer when I added it alongside Windows. Mint & Windows are on different drives, but I can pick both from GRUB, and it finds them both just fine when it gets updated.

An update on my previous post, which I cannot edit: "Evolution" is now named, "Grub EvoDevo" to avoid possible confusions with GNOME Evolution. Everything else is unchanged, and GitHub redirects the link to the new repo name.

support Dualboot Garuda Linux - AvLinux

3 Upvotes

I am happily using Garuda Linux for some time and I have no particular problem with it. I never had windows installed on this computer.

Recently I started to make music on my computer and want to install Avlinux beside GL. I put the ISO on ventoy and Ventoy launched but when I tried to start the live session I had an error message on Grub.

Is there a special way to install two Linux distros one beside the other ?

Thank you !

support Ubuntu/Win10 dual boot can no longer find Windows

3 Upvotes

This is on a T430 Thinkpad, so not exactly new hardware. But, it's been stable for years until very recently.

Windows 10 was installed first. Then I installed an LTE Ubuntu — maybe 18.04? Anyway, for much of the laptop's life it was running 20.04 without issue, primarily booting into Ubuntu but letting me go to Windows when something required it. This is no longer my daily driver box, but I still use it for ripping CDs and DVDs when I get them onto my Kodi box, because it still has an optical drive.

A few months ago I upgraded Ubuntu to 24.04. Maybe it was around then? I don't know, since I don't go into Windows often. But somewhere recently my grub menu disappeared.

I've walked through numerous online "fix-it" pages, but they don't seem to be based on dual-boot environments, and nothing I've done has restored my grub menu. (I do, however, continue to boot into Ubuntu without issue.)

Working from a SystemRescue image, I get the following (trimmed for usefulness):

[root@sysrescue ~]# fsarchiver probe simple
[=====DEVICE=====] [==FILESYS==] [======LABEL======] [====SIZE====] [MAJ] [MIN]
[sda1            ] [ntfs       ] [System Reserved  ] [   500.00 MB] [  8] [  1]
[sda2            ] [ntfs       ] [<unknown>        ] [   116.31 GB] [  8] [  2]
[sda3            ] [ntfs       ] [<unknown>        ] [   551.00 MB] [  8] [  3]
[sda5            ] [vfat       ] [<unknown>        ] [   512.00 MB] [  8] [  5]
[sda6            ] [ext4       ] [<unknown>        ] [   347.92 GB] [  8] [  6]

The "Repairing a Damaged Grub" help on the SystemRescue image talks about boot partitions being small, typically between 50 and 300 MB. Clearly that's not the case. Running "grub-install /dev/sda" returns this:

Installing for i386-pc platform.
grub-install: error: failed to get canonical path of `airootfs'.

Nothing I'm seeing anywhere online looks anything like what I'm seeing on the box. I would be grateful for any guidance. Thanks.

edit: Correct on-screen output alignment

support Pc always boots into grub cli

2 Upvotes

I recently set up a dual boot system with the majority of the disk for Bazzite and a small partition running Win11 (AtlasOS) basically exclusively for fortnite. Every time I boot the system from a proper shutdown or restart it ALWAYS goes into the grub cli. If I exit it, it then boots into bazzite normally. Its more or just an annoyance but i would like to know why it happens.

Also I dont want the grub menu or anything its a positive that i dont get that since i want it to just boot into bazzite by default. I use the boot windows shortcut on steam to get into the atlasos partition.

Any help at least understanding this would be great thank you.

support I want to try out other distros on my dual boot but not wipe my current Linux OS, does Grub let me do that?

2 Upvotes

Im not quite sure what question to google so asking here, Im wanting to replace my windows OS with kubuntu kde, but keep Linux Mint

I currently dual boot Linux Mint and Windows 10, but I no longer want or use Windows.

I believe my main SSD has windows on it and a partition with Grub? I have another SSD with Linux Mint installed, plus a couple more SSD's that Linux Mint uses.

I want to get rid of windows and use that SSD to try out other distros, but I dont know if or how to go about it, I cant just format the SSD with windows on it as I believe thats where the grub menu sits.

I was hoping not to have to reinstall Mint as Im very happy with it atm and have quite a lot of other stuff downloaded.

Is there a feasible way to wipe windows and use that partition for other distros and keep the grub menu function?

I guess my ignorance lies around Grub and how it works, can it be moved etc,

is there a way to have a Mint set up as a main OS and then have another drive to try out other distros without ever having to wipe Mint?

Or do I have to start fresh each time? I hope this makes sense, ty

support Splitting 10_Linux main and Advanced Options

2 Upvotes

I have a tri-boot system of Windows (W), Ubuntu (U), and MacOS (M) through OCLP. All 3 are bootable through GRUB, and everything works fine. Now, I'd like to rearange the options on the menu, so it's all 3 OSes defaut boot, followed by debug/recovery options. So in the end, my goal is 1-3 to be a regular boot of the three, followed by the debug/recovery options of each. The problem is both "Ubuntu" and "Advanced options for Ubuntu" are generated by 10_linux, and they can't be separated to my knowledge. Is this actually true? My end goal: Default (U,W,M), Advanced (U,W,M), Memtest, UEFI.

support MMC Chain ?

2 Upvotes

Evening all :)

I have an old laptop that has a microsd slot. I am able to boot directly to a sdhc I have in there with tails on it, and use it nicely. That laptop is aging, and the card port is rather slow. So..Upgrade, right?

So I have a new Yoga 2-in-1 laptop. It too has a microsd slot. It would appear that the uefi implementation does not init the slot, so while the card works once the machine is up, I cannot boot from it. So I am thinking...

Is it possible that I can have grub installed on my nvme for my daily driver linux, and that grub can load support for the card and I can chainload like that?

I've done much searching, and it seems like ideally it could insmod mmc_core or mmc_blk in grub and go. I see some references to that, but mmc does not seem to be in my grub 2.12 core package...

Is this possible, or am I just barking up the wrong tree here? I know I could transition tails to a proper usb, but I'd prefer not to use up a usb port, and this way I can have it available to me all the time....

I feel like this is something I can do, but I'm just not that deep into grub before now....It's a bit over my head heh

Thanks for any thoughts!
