If a picture is worth a thousand words, here is 2K:

enter image description here

The top is gparted and the bottom is the terminal.

gparted lists partitions in sector order:

  • p1, p2, p3, p4, p11, p5, p8, p6, p7

The terminal lists partitions in lsblk order (using the alias lsdrv):

  • p11, p7, p5, p3, p1, p8, p6, p4, p2

There are partitions deleted in preparation of Ubuntu 24.04 install:

  • p9, p10

It's noteworthy that partition p11 used to be p9 with the flags hidden, diag but after copy & paste the flags were changed to msftdata. I haven't booted Windows 10 in years so I may never know if this will be a problem...

Some say fdisk may solve the problem and renumber the partitions in order, but I haven't found a definitive answer. How can partitions be renumbered in the order of:

  • p1, p2, p3, p4, p5, p6, p7, p8 and p9?

  • I take it this SuperUser answer is the fdisk solution that doesn’t do what you need? 🤔

    @matigo I had tried that SuperUser answer before posting my question but it told me device not found which led me to believe nvme devices weren't supported. However I must have spelled the device wrong because it works now. I'll delete my question later today after you read the comment. Thanks.

    Generally renumbering is a bad idea. Any place still using device like /dev/sdX or /dev/nvme0nXpY will then be wrong. You can use gdisk. rodsbooks.com/gdisk/walkthrough.html I would make sure to have really good backups including a backup of the current partition table just in case sudo sfdisk -d /dev/sda > PT_sda. And same for nmve drive's partitions.

  • @oldfred Great advice as always. Long ago I used to always buy new SSD's, PCMIA's, NVMe's and SDRAM cards so I had learned to always use the mount name. In etc/fstab it's by UUID of course so that is the only thing I would have to change to point to the mount name. I'll rescind my idea of deleting this question because your excellent comment will go into the dust-bin. I'll post an answer of what I did to solve the problem and add your caution to backup and recommendation for gdisk by Rod Smith.

This is a duplicate question for Stack Exchange because the solution is posted on Super User: How to renumber a partition?. I'll use artistic license and post an answer here in Ask Ubuntu and expand with additional details.

Firstly, please follow the comment by Old Fred to backup your current partition information:

  • sudo sfdisk -d /dev/sda > PT_sda

The fdisk program was used to renumber the partitions:

As per Old Fred's comment above you can also use gdisk: A gdisk Walkthrough

The lsblk command messes up the sort order in the first place. See: How to change lsblk sort order?. Following the link gives "nice" results (IMO):

$ lsdrv | sblk
