Hi everyone, I'm trying to dual-boot Windows 11 + Ubuntu 26.04.1 LTS on an HP laptop.
Ubuntu installation completed successfully, but after restarting, the laptop always boots directly into Windows. Ubuntu does not appear in the HP F9 boot menu or UEFI Boot Order.
My setup:
- HP laptop
- Windows 11 already installed
- UEFI/GPT
- 1 TB NVMe SSD
- Windows partition:
nvme0n1p3 (~511 GB NTFS)
- EFI partition:
nvme0n1p1 (~210 MB FAT32)
- Ubuntu partition:
nvme0n1p5 (~511 GB ext4)
- Ubuntu was installed manually using the free space
- Windows partition was not formatted/resized
- Secure Boot was initially disabled during installation; I've since enabled it again
- Enable MS UEFI CA key is now enabled
Ubuntu's EFI files definitely exist:
S:\EFI\ubuntu\
grubx64.efi
shimx64.efi
mmx64.efi
BOOTX64.CSV
grub.cfg
Windows can also access shimx64.efi:
Test-Path "S:\EFI\ubuntu\shimx64.efi"
True
I also created a BCD entry from Administrator PowerShell:
Ubuntu
device = partition=S:
path = \EFI\ubuntu\shimx64.efi
bcdedit /enum confirms the entry exists.
However:
bcdedit /enum firmware
still only shows:
{bootmgr}
USB Drive (UEFI)
No Ubuntu firmware entry.
The HP F9 menu currently shows only:
OS Boot Manager (UEFI) - Windows Boot Manager
Boot From EFI File
I also tried F9 → Boot From EFI File → internal NVMe → EFI, but the HP EFI file browser doesn't show the ubuntu folder properly.
Where am I stuck, and what is the correct/safest way to get HP UEFI to recognize Ubuntu without replacing or modifying the Windows EFI bootloader as I need Windows for placement exams ?
I would especially appreciate help from people who have dealt with firmware issue + Ubuntu 26.04 dual boot.Hi everyone, I'm trying to dual-boot Windows 11 + Ubuntu 26.04.1 LTS on an HP laptop.Ubuntu installation completed successfully, but after restarting, the laptop always boots directly into Windows.
