How to clone a bios_grub partition?

no flag

I want to create a clone of my SSD. My partition table looks like this:

However when using Clonezilla (which uses Partclone) in the dd mode, it fails to clone the first 1MB bios_grub partition (BIOS boot). When trying to make a clone in the "disk-to-image" mode, it also fails.

How to go about this? Alternatively, since I'm booting exclusively in UEFI mode, is it safe to simply delete this partition?

The bios_grub is only requried if booting in BIOS mode. ESP - efi system partition is only required if booting in UEFI mode. When first starting to use UEFI on new system, I would add both, but you only need one or the other. You also do not need a swap as large as you are showing. Ubuntu's default is a 2GB swap file. Many with servers still suggest a 4GB swap partition. But my desktop use never uses any swap.

If all you want to do is copy the bios_grub partition it should be possible using GParted. You will need some unallocated space on a backup drive (not unused filesystem space). It’s then a simple copy/paste operation

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
