Inspiron 16 plus - Unable to setup Ubuntu along side windows after BIOS update
I recently bought a laptop and set up ubuntu at the end of Feb 2025. Then there was a bios update and since then I have not been able to set up dual boot. First ubuntu itself got vanished along with grub. Once I tried to boot using usb, even windows got corrupted and I had to clean install windows. I have disabled secure boot, fast start up on windows. Now trying to install Ubuntu from live usb, it failing with grub installation error.
Command ['unshare', '--fork', '--pid', '--', 'chroot', '/target', '/usr/lib/grub/grub-multi-install']Exit code: 1Reason: -Stdout: ''Stderr: Installing grub to /boot/efi
I have added efi_no_storage_paranoia as the last parameter on the line with linux in the UEFI settings, still it didn't work. The error persists.
No Events found!

Hi
So my suggestion is try here https://discourse.ubuntu.com/ for specialised help.
If W11 is installed and running, could you post a picture of your storage device, using Gparted from the live Ubuntu installer? The visual info may very well help, posted mine as a reference.
In Feb did you install Ubuntu with Secure Boot enabled and as a GPT uEFI installation, using the windows boot loader area to install GRuB?

Hi @anne_droid ,
Thank you for your response. I was able to dual boot along side windows11 in feb until after the BIOS update. I had and I have disabled secure boot before trying to set up ubuntu. The grub installation keeps failing.
Here's the requested data for your reference:

It seems the BIOS update has likely altered or corrupted the EFI boot configuration, which is why GRUB and Ubuntu disappeared. Since you're now getting a GRUB installation error, it's important to ensure your system is still set to UEFI mode (not Legacy or CSM) in the BIOS. Boot into the Ubuntu live USB and open GParted to verify that the EFI partition (usually a small FAT32 partition around 100–300MB) still exists and is properly mounted at
/boot/efi. Also, make sure Secure Boot is disabled, which you've already done. If the installer still fails, you can try reinstalling GRUB manually using a chroot environment from the live session. This involves mounting your Ubuntu root and EFI partitions, binding system directories (/dev,/proc,/sys), chrooting into your Ubuntu installation, and then runninggrub-installandupdate-grub. This manual approach can often resolve GRUB issues that the installer can't fix.anne_droid

@speddinti
A coupla things...
sometimes a linux plays up if the BOOT area is not set to 250 MB minimum.
Yours isn't.
Maybe squeeze the mft reserved partition by 50 MB and expand boot efi by that 50 MB.
Because both have a 'warning triangle' next to them.
Your ext4 does not have an allocated mount point?
The post by @amelia_harris has some excellent content and may very well be the solution.

It appears that GRUB and Ubuntu vanished since the BIOS update probably changed or corrupted the EFI boot setup. Make sure your machine is still in UEFI mode in the BIOS because you are now receiving a GRUB installation problem. To confirm that the EFI partition is still present and correctly mounted, boot onto the Ubuntu live USB and launch GParted. Additionally, confirm that Secure Boot is turned off, which you have already done. You can attempt to manually reinstall GRUB using a chroot environment from the live session if the installer still doesn't work. Grub-install and update-grub must be executed after mounting your Ubuntu root and EFI partitions, binding system folders, and chrooting into your Ubuntu installation.
