Dual boot - Grub Issue after deploying

[Tedamp]

Hello everyone,

I have a problem on a dual boot (Win 10 / Kali). The computers are HP Z2 SFF G9 Worstation.

On my main computer there is no problem, I have a working “grub” and I can boot on each OS.

But after deploying the image, my other computer only boots on Windows. All the partitions are present in the Windows Disk Manager.

Any clue?

Thank you very much.

Hello,

I had the same problem during my dualboot deployments with Refind as boot loader. Even putting Refind first in the boot order on the master, when deploying my clients, Windows were almost systematically first (sometimes, multiple Windows entries). I solved the problem by creating a post-deployment script that recreates the BDC store with the desired configuration.

@glequeau Thanks ! I found a similar option.
I ran :

bcdedit /set {bootmgr} path \EFI\kali\grubx64.efi

on my master computer, and capture the image. I deployed this new image and after a reboot, I got my grub back.

@Tedamp Just to add to this topic: FOG does not mess with the EFI boot loader entries. You have to do this yourself. You might wanna read this topic as well: https://forums.fogproject.org/topic/16703/dual-boot-2-disks-unable-to-boot-grub/2
