Hello :raised_back_of_hand: I’d like some advice

Question 1.
What is the minimum number of partitions required for a clean, correct installation of Kubuntu 26.04 under the following conditions?
UEFI. GPT. Kubuntu 26.04 (manual partitioning in Calamares). No SWAP partition needed.
Will two partitions be enough?

  • EFI partition (/boot/efi) | FAT32 | 512 MB | “Bootable” flag.
  • Root partition (/) ext4 | No flags.

Question 2.
Scenario: Dual Boot: Windows 11 + Kubuntu 26.04.
I’m installing Windows 11 first, and it creates its own EFI partition.
Is it possible for both operating systems to share the EFI partition created by Windows 11?

Thank you!

Yes, you need at least those 2 partitions.

Yes, the installer will use that efi if it is present automatically, when using your guided install options.

i will just add that if a “correct installation” is one that requires hibernation capability, then there will be some extra steps and a swap partition is recommended.

but for simple sleep suspend/resume operations you are good to go.
