Hello, I wanted to create a disk partition for a VM with sudo fdisk but accidentally used EFI partition type and i think it became bootable and deleted some other disk partitions (some error messages poppep up that said it failed to delete some other disk partitions).
After restarting it loaded into grub and /boot is missing.
Tried using Boot repair iso but it just gave me the black screen with flashing underscore.
Loaded into ubuntu with an usb and got Boot repair from terminal but it's missing the Recommended Repair option.
Here's the summary file, any help is appreciated.
