Unable to change partitions on my disks

Question

I'm having trouble with disks on my machine. I'm unable to boot and currently trying to clean install Ubuntu. When I use Gparted with bootable usb disk, I can remove all partitions on my disk and when I hit apply button it says job is done but as soon as the success message disappears, it shows all the old partitions as they were before.

Update: when I use Disk utility, after hitting - button to delete any partition, nothing happens.

You could just format the whole disk. You can also use the Disks application. Many people find it more user-friendly than gparted. — Nmath, Sep 26 '21 at 09:57
Sounds like the failure to boot may in fact be a bad hard disk. Just a guess from experience. Can not boot can not edit partitions. — David, Sep 26 '21 at 10:05
Off the top of my head take it to another computer and try it there. — David, Sep 26 '21 at 10:11
Check disk SMART using GNOME Disks or GSmartControl. Share screenshot. — N0rbert, Sep 26 '21 at 10:26

If you're fine with wiping ALL data on the disk, boot to a Linux live USB and try these:

Run this command to wipe the first few blocks of /dev/sdb

sudo dd if=/dev/urandom of=/dev/sdb bs=4M count=50 status=progress && sync

Reboot to the same live medium.
Create a new Partition Table ("gpt" for newer EFI systems and "msdos" for older Legacy Boot systems) using GParted.

I did it with no success. It seems to me any write operation to the disk won't work. – Mehraban Sep 28 '21 at 07:04
That means either:
1. The disk is damaged (hardware failure)t is read-only (some SD card holders and some rare kinds of disks, USB disk enclosures, USB-SATA etc., have a switch that makes them read-only).
