How can I extend my Ubuntu Linux partition to the left without breaking UEFI boot?

enter image description here

  • I have an Ubuntu Linux partition /dev/nvme0n1p5 that I wish to extend to the left.
  • On the other side, I also have a Windows partition /dev/nvme0n1p3 that has been shrunk for that reason.

I'm afraid that if I extend the Ubuntu partition to the left that the GRUB boot will be broken. How can I safely extend this Ubuntu partition to the left?

This will not break Grub. But you should have good backups, just for the case something goes wrong like a power outage. It will need long time, all data in the partition will be moved, so be patient.

Then how does the system initially knows where to point when booting then ? Grub needs to be stored somewhere, right?

You won't have a problem resizing the partition. Grub is on one of the smaller partition .

If you can manage it I'd recommend getting a second drive and have Windows on one drive and Ubuntu on the other.

1 TB SSD are less then $100 US.

The OP already has a NVMe 1TB drive, more than enough for half a dozen OSes, let alone just Ubuntu + Windows. And depending on the price it can make a lot more sense to invest in a slower yet larger for cheaper HDD drive to have with a data partition (NTFS) to be shared by both OSes and contain personal files / multimedia, etc.

What do you mean that GRUB is on one of the smaller partition ? I'm not asking about having a second drive. If I could, I would already have. I'm on a ultrabook with a single slot for NVMe drive, so that's not even possible.

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.
