Garuda renamed my hard drive in UEFI after install and now can't boot it

Hi, kinda lot to explain here

Basically I naively attempted to install Garuda Linux on my HDD, replacing an old Ubuntu partition at the start of the disk. There is another partition on the disk as well, a Windows 7 one.

Anyway it all failed as the installer was running in UEFI mode whereas the disk is MBR formatted and there is no EFI partition there or anything like that. I think the installer created a boot/efi folder on my other Windows 7 install on another disk (an SSD) or something, but of course it does nothing.

So anyway fast-forward a whole bunch of research about MBR, GPT, UEFI, bootloaders, and all the rest of this stuff - I have since deleted the failed Garuda install. And in fact moved via Gparted my Windows 7 partition which I had on my SSD, to the HDD in place of the non-booting Garuda partition. So now I have two Windows 7 partitions on the HDD.

You see my SSD was MBR formated too, so my plan now is just to format it as GPT and install Garuda on it, with hopefully no more issues.

However there’s a problem, as the HDD which now hosts the 2 Windows partitions, is still named as ‘Garuda’ in the UEFI, and moreover - doesn’t boot. If I attempt to boot from the disk it just blinks and throws me back to the boot menu in less than a second. I tried reinstalling the MBR on it (via sudo dd if=mbr.bin of=/dev/sdb), I tried EasyBCD in an attempt to restore the MBR and bootloader on my HDD, I tried using boot-repair-disk to restore the MBR and bootloader, I tried to reinstall Windows 7 in the hope that it would do some magic. Nothing seems to work.

I don’t know what else to try. Perhaps installing Grub Legacy from the boot-repair-disk on my HDD, dunno if that’s even a possibility without a Linux install on the HDD to host supporting files on, but maybe. If that doesn’t work though then I’m out of ideas.

What could be the problem here?
Did the Garuda installer write to the NVRAM of the UEFI? If so then what can I do to revert it? Resetting the UEFI to defaults I’ve already tried too.
The problem doesn’t seem to be with the MBR, nor the lack of a Windows bootloader; both Windows partitions on the HDD have BCD folders.
The first Windows 7 partition on the HDD starts at sector 2048, there is 1 Megabyte free in front of it. Which I know is used to host a Grub image or something when you have a Grub install, but when you just have the MBR/Windows bootloader, could that space before the partition interfere with something?

First Happy holidays, Hope they are great.

Now please launch your Terminal, enter garuda-inxi, copy that text, then paste it here with 3 ~~~ above and below the text so it looks like the below. I’m assuming your motherboard is UEFI / MBR since you have both partition table types on your drives. Please correct me if I’m wrong. Since you attempted to reinstall Windows Can I safely assume you don’t care about the two copies you have installed? If that is the case I would just wipe all copies of your OS’s and start over using only UEFI and making sure the drive or drives you want your OS’s on have a GPT partition table. I would boot into your Garuda live key and delete the partitions using the partitioner in it and then once deleted go to Devices at the top of your partitioner and select create new partition table and then select GPT. If the fact that you have erroneous entries in your boot list in your BIOS you can now simply go to tools and select load optimal defaults, press F10, save and reboot.

Now as for reinstalling the OS or OS’s. If you want both Windows and Garuda then install Windows first it will now detect you have a GPT partition table and install appropriately for that partition Table. Then once you have installed Windows I’d go in Windows once do it’s updates, reboot into it to verify that the updates don’t have issues, if not reboot and boot into your live Garuda and when you get to the partitioning either select a separate drive from the Windows drive to install to or select install alongside and the partitioner will shrink the Windows partition and allow you to install Garuda right behind it. Now once Garuda is installed reboot and you should see the Garuda Grub menu with both Garuda and listed on it.

If you don’t care about Windows then just boot into your live Garuda and install.

About 2 weeks now of toothache and trying to install Garuda :expressionless:
I’ll get my tooth fixed, hopefully for the final time, on Wednesday, and it would sure be great if I could get on top of this Garuda thing by then too :slightly_smiling_face:

Well if you mean that my (laptop) motherboard supports both GPT and MBR partition types then that’s quite correct. It’s definitely an old motherboard though, the first generation to support the UEFI standard I think (running Phoenix SecureCore Tiano). It doesn’t support Secure Boot or any of that newer stuff. I do have the capability to boot into the EFI shell as well if there’s anything I can do to help things from there.

As I mentioned, I copied one of my Windows 7 partitions from my HDD to my SDD (after the attempt to install Garuda on the HDD failed), and I haven’t deleted the same partition from the SDD yet, so I have 2 copies of it and on the HDD copy is where I attempted to reinstall Windows, as an experiment. I’ll wipe that Windows reinstall and recopy from my SSD shortly.
I do care about both of the Windows partitions I have and would like to preserve them as is, if possible.

Here’s the garuda-inxi output when booting from my Live USB:

Two questions to start with come to mind. First how big is the SSD? Second if it’s 256 gigs or more why not install your OS’s to it and use the HDD for something else?

My SSD is 128 Gb, so it would be great for a Garuda install while the HDD is 320 Gb and split between two partitions of Windows 7. I plan to use Garuda as my main OS from now on, so the extra speed of the SSD will come in handy.

I ran boot-repair-disk and it also generates a report.
/dev/sda is my SSD, and /dev/sdb is my HDD (/dev/sdc is just my USB live disk)

Of interest is what I highlighted in bold, the section where the UEFI generates a report
Boot0005 appears to be my SDD
Boot000E is my HDD, and as we can see it’s called ‘Garuda’ in the UEFI (it lost its previous hardware name when I first attempted to install Garuda), and moreover it appears to look either for an EFI partition or a file EFI/Garuda/grubx64.efi, which of course does not exist. The disk is MBR formatted and I deleted my Garuda partition from the disk anyway.
Anyway this information appears to be saved in the NVRAM of the UEFI, rather than in the MBR or anywhere on disk (tell me if I’m wrong). Question is, how do I change it back to what it was? Or at least to something sensible that will allow the MBR and then Windows bootloader to be loaded?

Yes, the Grub installation will add an NVRAM entry unless you run it with the --no-nvram flag.

You can delete it from the live environment with efibootmgr. With no arguments it will list all boot variables:


To delete a boot variable, identify the entry you wish to modify with the -b flag and pass the -B flag to delete it.

sudo efibootmgr -b 0000 -B

You should be fine to go ahead with the installation with or without removing the old boot variable first.

Note: you will not be able to get Windows and Garuda on the same bootloader if one is installed in UEFI mode and the other is installed in legacy/BIOS mode. You will have to switch from one to the other in the BIOS every time. Additionally, you may need to disable CSM for one and re-enable for the other each time as well, depending on how your mobo is configured.


So I enter the command sudo efibootmgr -b 000E -B then in my case, and it will remove the Garuda entry from the UEFI NVRAM?

OK good, that’s what I’m looking for, but in that case how will the UEFI identify that HDD? Will the HDD revert to its default hardware name and boot procedure, or will it disappear from the boot menu altogether? If it disappears altogether, then how do I add it back to the boot menu?

Of course, I realize that, and that’s absolutely fine. Main thing is that both drives are bootable and can be switched between in the UEFI.

Nothing was renamed like you are thinking, just a boot variable was added. Usually the UEFI can hold many boot variables. It is no problem to have multiple for one device.

That said, if it is an old/defunct boot variable (i.e. doesn’t point to a valid bootloader configuration) I would just go ahead and delete it.

Welp, I just deleted that boot variable, and now the SSD isn’t listed in the UEFI at all, I can’t even attempt to boot from it

Well actually it does show up as connected to Serial ATA Port 1 in the UEFI, it’s just not there in the boot menu

So what now, add a new variable?

Run the installer. :smile:

A disk with no bootable entries should not show up in the boot menu, so you are describing the expected behavior.

I don’t want to run the installer as I will install Garuda on my SSD, which currently has a Windows 7 partition on it (that I copied to the HDD too).

However prior to wiping that Windows 7 partition from the SSD I first want to check that I can boot it and the other one from the HDD.

And moreover how will installing Garuda on the SSD fix the HDD and its lack of an entry in the UEFI? (the HDD in the current configuration is MBR and has no Linux anything on it)

Sorry my bad, I meant HDD* here, that’s the drive which I can’t access in the boot menu. The SSD is fine.

The HDD has no UEFI-mode installations and no EFI partition so it’s a little different. If you can’t boot to it, check that CSM is turned on or that “UEFI only” mode is turned off in the BIOS settings.


I can’t boot to it as I just deleted its entry in the NVRAM, you said it yourself, and the previous entry it had in the NVRAM I presume was deleted or overwritten by Garuda when I first attempted to install it on the HDD 2 weeks ago (I since deleted that partition).

Going back to my post above Garuda renamed my hard drive in UEFI after install and now can't boot it - #6 by flamming_python
It looks like Boot000D could be its previous entry in the UEFI, before the Garuda installer added its own one to the NVRAM. However I don’t see that entry in the boot menu and can’t select it.

My UEFI is first-generation and doesn’t even have the option to boot as ‘UEFI only’ or ‘Legacy’, what it boots as is entirely dependent on what drive you select in the boot menu. If I boot from my Garuda Live USB it boots as UEFI/GPT, and If I boot from my Windows 7 partition on my MBR-formatted SSD then it boots in BIOS/MBR mode. If I was able to select the HDD in the boot menu, then there wouldn’t be a problem I presume.

The NVRAM entry is not the disk, nor is it representative of it. This is the NVRAM entry:

As you can see, it points to a Grub configuration file on the EFI partition.

Your idea that a boot variable was renamed is not correct.

It sounds like something that happened with this effort did not produce a bootable entry:

It looks like your USB stick is actually formatted GPT. If you need it to be in legacy/BIOS mode you could format it as MBR (Ventoy supports this).

Yes I get it, the NVRAM is a memory chip on the motherboard, but I presume these NVRAM boot variables amount to instructions for the UEFI as to what devices are bootable and how they are booted.
Else what is the point of the same Garuda writing an entry to the NVRAM that details the EFI partition and the location of the .efi file within it?

I can access both of those Windows 7 partitions by booting in Garuda from the USB, browse their files, and chkdisk didn’t find errors in them, but point noted, it could be that when I actually get into the Windows bootloader on my HDD, it won’t be able to boot them.

However I’m puzzled as to how that can be the present issue, because the present issue is that I can’t even select the HDD from the UEFI to even attempt to boot from. So no MBR code being read, no Windows bootloader, nothing. There is no entry for the HDD in the UEFI boot menu, only for the SSD, and the USB pen drive and some other stuff such as the EFI shell and boot from network.

Even if I were to reformat my HDD, and reinstall Windows 7 on it, I still won’t be able to boot from it, because again, it doesn’t show up in the UEFI. Well unless the Windows install process adds a new boot variable to the NVRAM itself I suppose.

Indeed it is, and had I realized that the Garuda installer switches to MBR or GPT mode depending on how the Live USB is booted, and that I can switch how its booted by an option in Ventoy, then my initial attempt at installing Garuda onto my HDD might have been successful.

However now this is all a moot point, as my plan now is anyway to simply wipe the SSD, format it as GPT, and just install Garuda on it alone. Leaving the HDD to my Windows partitions. However before I do that I want to first be able to boot from my HDD and get to the Windows bootloader.

Stick in a Windows install ISO and click…oh, wait, you’re on Windows 7? Nevermind.

It would greatly benefit you to thoroughly read through several portions of the Arch Wiki regarding MBR vs GPT, EFI, Bootloaders, etc. Your presumptions are not supported. Maybe you have a clue under Windows; Linux not so much.

Secure your data. I know a Windows 10/11 installer ISO can repair Windows Boot/EFI entries. Something as ancient as Windows 7–who knows? :person_shrugging:

I don’t have a clue about anything

Everything I learned about partitions, partition-tables, BIOS, NVRAM, boot menus, boot loaders, and so on - I’ve learned in the past 2 weeks. So I’m sure that there is something I’m wrong about, but just telling me to read the Wiki doesn’t help - I’ve read about all this stuff countless times already and tried many things in an attempt to resolve my problem. Do be more specific.

To me it does stand to reason that the entries in the NVRAM act as instructions for the UEFI as to how to boot drives, else why are they there.
And that since the entry pertaining to my HDD is now missing, I’m not able to boot into it at all.

I guess this wouldn’t even be a Garuda specific problem. Were it not for the fact that before I first attempted to install Garuda, I was able to select my HDD in the UEFI menu and boot into it. And, now I’m not.
Washing your hands of the affair and saying ‘you’re on your own bro, Windows 7 is ancient’ is fine, I’m not paying anyone for technical support here, but at least in the interest of Garuda itself, which bills itself as something of an Arch for the masses - someone should probably look into this whole thing. And maybe add an option to the Boot recovery utility that’s already accessible from the Live USB, to like remove the Garuda-entered NVRAM entry and restore a default one that instructs the UEFI to just read the MBR (if it’s detected that the disk itself is formatted as MBR), or something.

I think this is how you have decided to “bill” Garuda, not how Garuda bills itself. From my perspective it is a community/hobby distro made by people who use it or contribute to it because they like it. You would probably be surprised how few active contributors there are.

As for your “someone should probably look into this whole thing” comment, you are still making it out like a bug or error happened, which I am not convinced of.

This comment makes me feel like you are still incorrectly associating the boot variables with the fact that Windows is not showing up in the BIOS boot menu. There is no use repeating myself over and over on this point, so what can I do but shrug? Let the record show that I am certain this is not the case.

By the way, efibootmgr is a utility that can be used in the live environment, as you already know.

Have you tried booting without the USB stick inserted?


Hey, you’re the boss. Just sharing what I thought.

So what is your proposition, as to why the HDD is no longer showing in the UEFI boot menu?

Yes and thank you for pointing me to it. I’m currently reading the documentation and browsing other forum posts about it. Unfortunately, everything I’ve seen seems to suggest that it can only write EFI/GPT boot entries, not ones for MBR/BIOS drives and partitions.

So I don’t know. I guess I’m kind of screwed. If I don’t think of a war to resolve this, I will have to convert my HDD to a GPT partition table, while somehow preserving the partitions and their data, I’ve heard that this is possible. Then I will have an EFI partition, and I can add the EFI entry to the NVRAM, and it should boot, at least as far as the bootloader. But I’m not sure if the Windows 7 installations will themselves boot in that case, as they were installed in MBR/Legacy mode.

Yes. Then I have only three options. SDD, EFI shell, and Network boot.
