When i try to mount my dev sda 3 or 2 it says mount: /mnt: wrong fa type, bad option, bad superblock on dev/sda3, missing codepage or helper program, or other error. dmesg(1) may have more information after failed mount system call
At 4:44, when I run 'grub-install /dev/sda' I get an error: Cannot find EFI directory. I've dual-booted Ubuntu Jammy with Windows 10, both on separate partitions in Legacy. What should I do?
All my drives were wiped by accident, I wanted to fully wipe Linux and reinstall Windows 11. But I can't get Windows installed because the installer doesn't recognize Linux partitions.
@DrewHowdenTech just figured that out, I'm using gpart currently, can't format to GPT on Linux, but Windows installer does recognize NTFS, so I formatted to that. Gonna convert it to GPT in Windows installer then finish installing tiny 11, since I need Windows on my main laptop for compatibility with Youscian and VMWare, both of which wouldn't run properly or at all on my system for some reason
If you go to “Create New Partition Table” (in one of the menus on the menubar, can’t remember which one), GParted does have an option to format the disk as GPT. Just make absolutely sure that you have selected the right disk, and that there is nothing on it that you need, because it WILL BE ERASED! Also keep in mind that you’re doing this to the DEVICE, not an individual partition!
I tried your method on a VM of Jammy Jellyfish and it seemed to work well, but when I tried it on my SSD I still get the following error: Error: invalid environment block. 452: out of range pointer: 0xcfff020 Aborted. Press any key to exit. Hitting a key on the keyboard continues the boot process but I never had to hit a key for the OS to boot. If you know what is happening could you give me a hand on trying to fix this? Thanks!
Drew - Good job. But I'm still not getting a menu for me to select my windows or linux mint (22) install. However, I should note that my BIOS is not showing any linux in the boot order. I had installed LM a couple weeks ago from a USB stick and it ran fine. Not sure if it is pertinent, but I had not rebooted until I needed to do something in Windows. And when I rebooted into Windows, it said it had a security update it wanted to do, and I let it. Soon after, I tried to reboot into LM, but could not find any way - other than booting again from my (live?) USB. Then, if I bring up a Files app, I can see the partition (84 GB /dev/sda8) and the LM files in it. But no way to boot into it. I've tried grub-repair, and been thru several youtube vids inclucing this one, but nada. I did get a cpl of Warnings during your "grub-install /dev/sda" step stating "EFI variables cannot be set on this system." and "You will have to complete the GRUB setup manually". I didn't know what I had to do at that point. I don't have any data to speak of on that install yet - just setup of printers, etc, so I'm seriously thinking of redoing the install. (sorry for the long post...) Any suggestions?
@@DrewHowdenTech I was still at # so I just entered "update-grub". Ran ok except for a warning that it was executing os-prober. Finally said it was Adding boot menu entry for UEFI Firmware Settings... done.
The problem for me is that with the other video you don't show how to do it if you've got a separate boot partition like you mentioned. So I'm guessing that it only works for ubuntu based systems or certain installation methods.
This method is even easier. It's actually the exact same regardless of whether your /boot is on your root partition, or another partition. Only difference in the latter case is that, in addition to mounting your root and EFI System partitions, you also have to mount your boot partition at /mnt/boot (after mounting your root partition, but before mounting your EFI System Partition).
whenever i try to chroot it says failed to run command '/bin.bash' : no such file or directory. im trying to recover a digital ocean droplet after it was destroyed by an angry ex-admin
Check to make sure that you are chrooting your ROOT partition, but that would indicate that there is more missing from your installation than just your bootloader. At this point, your best bet would be to extract the drive and copy the data off (hope your ex-admin didn’t delete that too).
@@DrewHowdenTech you respond so quick thankyou. from the looks of it, he blocked all ports (cant access anything) and then just deleted any boot files? how would i extract the drive?
Well, if you’re able to boot this system from a flash drive (to try chrooting), that would mean you have physical access to the system, right? If so, open it up, take out the drive, and connect it to a working computer, using a hard drive dock or something like that. You can also copy any data to an external drive, using the live USB. NOTE: I am writing the above with the assumption that you own the system in question.
Ahh, you’re remote hosting. Are you able to access the contents of the drive from DigitalOcean’s dashboard, or some other way over the internet (without booting it)? If not, are you able to access the contents of the drive from the recovery ISO?
Ahh, you’re running a dual-boot, and one of your distros boots just fine, and it’s just that the other one doesn’t have an entry in your GRUB menu. In that case, from within the Linux distro that is booting, run “sudo nano /etc/default/grub”, and uncomment (or add) the line “GRUB_DISABLE_OS_PROBER=false”. Then run “sudo update-grub”.

Make sure you’re booting your USB in legacy mode.

You can erase your disk from within the Linux ISO.

I get a chroot segmentation fault error do u happen to know what this is?
This looks identical to your first video.

Run "sudo update-grub" from within your Ubuntu, and paste the output here.

Did you run “update-grub” after reinstalling grub?
@@DrewHowdenTech I was still at # so I just entered "update-grub". Ran ok except for a warning that it was executing os-prober. Finally said it was Adding boot menu entry for UEFI Firmware Settings... done.
And, doesn't there need to be a "Linux..." or "Ubuntu" entry in the BIOS boot order, and the disk listings in there?
I would think there should be, but does it boot now?
@@DrewHowdenTech Nope.
10/10 keep up the good work.

Great video Drew :)
Thanks for sharing!
I need help. It won’t work. I need this. computer! Please help
What part are you having trouble with? Are you getting an error message? If you are, what does it say?
Followed everything. No errors. Didn't work.
What is the output of “grub-install /dev/sda” and “update-grub”? Also, what’s happening when you boot the system?
@@DrewHowdenTech I reinstalled linux put the grub in the efi partition and it is working. Thanks.
doesn't work
What step are you having trouble with? If you are getting an error message, what does it say?
when I try "grub-install /dev/XXY" I got "grub-install: command not found". Any idea?
Did you set up the bind mounts shown in this video? Are you chrooted into your Linux installation?
Ahh, you’re running a dual-boot, and one of your distros boots just fine, and it’s just that the other one doesn’t have an entry in your GRUB menu.
