HP455G2 UEFI settings for dual boot Win 10 and Ubuntu

HP Recommended
HP455G2
Ubuntu LTS

Good evening all,

 

Can anyone advise me please?  I have updated the system UEFI-BIOS to the latest version. I have installed Windows 10 and Ubuntu 21.04, both under UEFI. What UEFI settings to allow me to access the Grub dual boot menu, please? I can either enter only windows, or get stuck in a no boot loop. Actually I can enter the Bios menu and load Ubuntu from there, but this is a very convoluted workaround at best.  Or, should I start again; installing both operating systems in legacy mode?

 

With thanks in advance,

 

Springnuts

Thanks WAWOOD.   I installed both OS under the UEFI bios (using Rufus to create the installation media etc). 

 

In fact I managed to sort it out - used the boot selector to boot into Ubuntu; then used the "boot-repair" utility (default advanced options) ... rebooted ... and the laptop went straight into Windows. This was as expected, since it appears that this UEFI firmware does not allow the boot order to be changed. However, boot-repair did suggest that this might happen, and it also suggested the workaround: I used an elevated command prompt to change the default boot entry of the Windows bootloader: bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

 

Hey presto, the laptop now boots into grub; giving you the options of continuing into either Ubuntu or Windows.

@Springnuts 

I'm sorry, but HP does not provide support for Linux distros.

IF you replace the preloaded Windows OS with a Linux distro, or add a Linux distro, then you assume full responsibility for maintaining that -- including solving any problems with booting the other OS and/or installing the other OS.

Modern PCs with UEFI, instead of the older BIOS, are especially difficult to install because you have to go into the UEFI settings and make several changes before you can even boot from a USB stick -- and we are unable to assist in that work.

Your best bet for support now is to contact the support forum of the distro you are using.

Since you are using Ubuntu, go here: https://ubuntuforums.org/

Good Luck
