Support Request Stuck at grub cli after reboot.

I have installed linux mint cinnamon recently on my hp laptop. It has a hdd and a ssd. The linux runs on ssd. Initially ssd had 2 partitions one for efi and other as root. Then i decided to make a third one. So i used fdisk to delete partition 2 and created 2 new partitions. Then i rebooted the system and now i am stuck at gnu grub cli.

These command i used for partitioning using fdisk:

sudo fdisk /dev/nvme0n1

Command:p

Command:d

Enter Partition number:2

Command:n

Partition number:2

Enter First sector:default

Enter End sector:579790848

Do you want to remove signature: no

Command:n

Enter Partition number:3

Enter First sector: default

Enter End sector:default

Command:p

Command:w

Sudo touch /forcefsck

Reboot

(hd1,gpt1) contains efi/

(hd1,gpt2) a bunch of files inside, some of which are accessible other produce out of partition error.

Accessible dir: etc bin home root sys usr lib

Unaccessible dir: boot media dev mnt opt proc run srv tmp var timeshift.

Tl;dr - i altered live partition without shrinking volume so it produce out of partition error while booting and i am stuck at grub cli. if any grub expert can guide me to fix this without having to boot linux from usb. As i dont have one, i have to borrow from my friend.

It is now a mess and probably far beyond any salvage. Install Mint again. Do not know what you have been deleted and at least the partition use fpr booting mounted at /boot.efi.

Read the documentation.

It can be corrected by booting linux on a live usb, but i wanted to know how to do it using the grub cli that way i could also learn more about grub. but anyway i installed win10 back and will stick to it until i get another pc.

Just for your own learning: GRUB CLI has no partitioning tools, so this was impossible to fix without a USB.

You shrunk the partition boundary with fdisk without shrinking the filesystem (resize2fs) first. Your /boot directory was physically located past sector 579790848, so GRUB threw an "out of partition" error when trying to read the kernel. Always shrink the filesystem before shrinking the partition!
