From what I understand, the boot EFI partition has become corrupted. In this case The easiest thing to do Is to download ventoy and install it in a flash drive Then put in this ISO, boot it and do the repair Https://sourceforge.net/projects/boot-repair-cd/ If that doesn't work then I should rebuild the efi partition and then restore the bootloader.

I flashed the boot repair ISO (64 bit) onto a usb drive using Balena Etcher. It was a normal morning, around 3 am, I had just turned off my pc (Ubuntu 22.04) normally, then the next day, it gave me this error: End kernel panic - not syncing: fatal exception in interrupt. Source: over 1 year ago
If you altered the MBR but haven't deleted the recovery partition, you can make it bootable again by installing GRUB and os-prober (for example with the Boot-Repair disk). Depending on the type of recovery partition, it either comes up as "Windows Recovery Environment" or just "Windows 7", so don't confuse it with a standard Windows 7 installation.

I had a similar problem when I tried to install neon on a btrfs formatted drive. I'm not familiar with uefi though. You could try the boot repair disc https://sourceforge.net/projects/boot-repair-cd/ . The problem is that some packages normally get deleted after bootloader is installed, which won't happen here. You might need to remove them manually. That says my solution is not perfect and shouldn't be your first... Source: about 2 years ago
It sounds like you did all the right steps to fix the issue and restore the entry in the BIOS boot menu, too. You might repeat the steps and double check your work. Additionally or alternatively, you might boot up https://sourceforge.net/projects/boot-repair-cd/ ... That has worked for me w/o as much opportunity for pilot error; it will likely either fix the matter or give you some diagnostics you can share to... Source: about 2 years ago
Maybe somebody can help more than I, but I'd make sure that the BIOS has secure boot disabled, UEFI boot enabled, etc., because I've never seen a CloudReady or Flex boot fail if any "normal" ISO can boot. If unsure anything else boots, try say, https://sourceforge.net/projects/boot-repair-cd/ which also boots on about any system; if both won't boot, then mess with the BIOS settings; if one will boot but not the...

I mean have you booted from a Boot-repair live USB? Worth a try. Burn this iso into a USB and boot from it then follow menu instructions. Sometimes this helps when you have problems seeing an OS https://sourceforge.net/projects/boot-repair-cd/. Source: about 2 years ago
I've tested at least a dozen distros and the best so far (and by far) is Boot Repair Disk (https://sourceforge.net/projects/boot-repair-cd/), and it boots boots almost instantly, but then it nags me to update and starts an unsolicited boot repair. It is based on Lubuntu, but the official Lubuntu live disk is much more annoying with all the delay it adds to just booting ;-). Source: about 2 years ago
If you still want to repair it, I would suggest trying with boot repair disk, it worked for me in the past. I strongly suggest you do a backup anyway, better safe than sorry! Source: over 2 years ago
I made a Linux Live USB of a Linux Distro dedicated to repair bootloaders (I think it was https://sourceforge.net/projects/boot-repair-cd/ but can't be sure, it was a month ago). Anyway, it did the job and I was able to boot normally into Mint. However, the boot time is now slower than before, because the repair boot ISO made some kind of temporary file to allow booting that isn't adapted on the long (if I'm... Source: over 2 years ago
Another option is to use boot repair disk from here. It should be able to find the existing Linux install and reinstall the Grub bootloader. Source: over 2 years ago
In theory, the Windows 10 install media contains tools to repair the startup. I wouldn't bet on these tools to solve the issue though ( but I am a notorious windowsskeptic ) . You may have to do it in console mode ( using diskpart ) , or via a bootable linux rescue distributiion. Source: over 2 years ago
I attach a text file link from the result of the GRUB repair Live USB (I got it from here https://sourceforge.net/projects/boot-repair-cd/ ). Source: over 2 years ago
Do you think that Boot Repair Disk would help for this? Source: over 2 years ago
Try this Https://sourceforge.net/projects/boot-repair-cd/. Source: about 3 years ago
Try checking your installation medium for errors (there should be an option for it in the boot menu with the word "check"). Or try using Boot Repair to install GRUB instead. Source: about 3 years ago
