Boot is bypassing grub and going to windows

Greetings folks.
I just had an SSD installed and reinstalled ubuntu 20.04.3.
The install went fine but now I can't get my grub menu to come up. I have disabled fast boot in windows. What else can I try?
It's an HP Envy Touchsmart notebook
It's booting in efi mode as far as I know. One troubling observation, the /boot/efi directory is empty.
Thanks,
--glenn

G'day Glenn.

1. Does it boot into the 'buntu at all, or does it get stuck before the Grub Menu that does not appear?

2. Is the Windozer on the same SSD or a different drive?

Others will likely think of more questions but that's me for starters.

It boots ubuntu if I go to the F9 boot options. Everything is on the same SSD.

I tried changing the boot order with efibootmgr, but when I reboot it reverts to windows first again.

I even updated the BIOS hoping to get a submenu under OS Boot manager, no joy.

Thanks,

I'm doing a bit of brainstorming here, and I'll tell you that I have a road trip on tomorrow (Friday here) and Saturday, so in my absence there are likely others whom can help.

So you are able to get into a working Ubuntu, albeit with the PITA of going through F9 first?

1. Have you tried running

Code:
sudo update-grub

and rebooting? If so/not, what was/is the outcome?

2.
One troubling observation, the /boot/efi directory is empty.

What process did you use to determine that? Is there actually a sign of /boot/efi, or is that subdirectory non-existent?

Unless you told the Installer (Ubiquity) otherwise, it is quite possible that it used the ESP (EFI System Partition) that goes hand in hand with Windows 10/11 (which one is it?) to place the Linux bootloader.

3. Do you have Timeshift installed? If not, you can get it from Ubuntu's Software Centre.

Some of the options I am looking at for Glenn to try are as follows (if it helps Helpers), but I should say first Glenn to make sure you have your Windows safeguarded (eg USB Recovery), and perform these steps bright-eyed and bushy-tailed (fresh).

One thing - if you use your File Manager, or Terminal to determine if there is a presence of

/sys/firmware/efi/efivars

if there is content there, you have your system running under UEFI.

Option 1 (subject to Question 1) is to try reinstalling Grub form the Terminal of Ubuntu booted via F9.

Determine first what partition your Ubuntu root is on with eg lsblk, and then

Code:
sudo grub-install /dev/sdxy
sudo reboot

where xy is the alpha and numeric identifier for your root partition.

Option 2 would be, having installed Timeshift, take a snapshot, then use that to restore Ubuntu over the top of itself. The default, under the Advanced Options button in Timeshift is for it to rebuild/reconfigure Grub.

If you already have Timeshift installed and a snap already taken, that is no use to you if it precedes the time when you reinstalled on the SSD, so you would delete that first.

Option 3 - would be, armed with an Ubuntu Live USB stick, to use a process called

chroot

from the stick to enter your Ubuntu install and rebuild Grub from there.

I have Thread on Timeshift here if that helps.

Useful in the meantime would be if you can give us a screenshot of the GParted status of both drives.

Cheers

Rebooting boots windows.

I will try the option 2 timeshift trick and update this post with the results.

timeshift set up grub, but it still boots to windows.

I give up, esc F9 to boot the grub menu isn't that horrible. I usually just shut the lid and hibernate it, so I don't boot that often.

Thanks,

It has been my HP experience F9 as well with dual booting. I think it's a conspiracy.......

The AMD Ryzen / Asus MB desktop I just built (crap it was last year now) dual boots and no issues.

Back from my trip, thanks for that info, Glenn.

So Windows and Ubuntu share the same drive, and it appears that you installed Windows first and then Ubuntu, which is the correct sequence.

My humble apologies, I mis-wrote Option 1.

It should have read

Code:
sudo grub-install /dev/sdx (in your case, now, that is /dev/sda, no number)
sudo update-grub (I failed to specify that)
sudo reboot

and that would likely work.

If you want to pursue this you can, and I would ask for the content of (the // is a comment only)

Code:
cat /etc/default/grub

// and

cat /etc/fstab

but if you are OK with F9, your call.

Cheers

I would really like to get grub working. My bios doesn't have a submenu under OS boot manager, so I can't move Linux to the top. I did grub-install to /dev/sda and ran update-grub, but it's still booting to windows. I also tried changing the boot order with efibootmgr, it changes ok but upon rebooting windows is again first in the boot order. I think I have funky bios. I also updated the bios hoping to get a submenu under OS Boot Manager, no joy.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign-grub) and reinstall the grub-efi of
sda6,
using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s  use-standard-efi-file  restore-efi-backups 

Final advice in case of suggested repair: ______________________________________


Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 20.04.3 LTS CurrentSession entry (sda1/efi/****/grub****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi (**** will be updated in the final message)

I don't know about bcdedit, what are the asterisks meaning?

Thanks,
--glenn
