Setting up Dual Boot on an HP Spectre

November 8th, 2025

I have a HP Spectre and due to the BIOS on the system, it is tricky to get it to dual boot properly.  Here is what ultimately worked for me:

On my HP laptop I did as follows, step by step:

1 - Boot into Mint with F9

2 - Check where Windows boot loader is located

sudo efibootmgr -v

In my case /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

3 - Backup .efi file:

sudo cp /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi /boot/efi/EFI/Microsoft/bootmgfw.efi

4 - Replace original .efi file by the ubuntu one (the trick):

sudo cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

5 - Add windows 10 menu entry on grub. In my case, I wanted this to come first to match my other boot machines.  Create /etc/grub.d/27_ssz_custom with the following lines:

 

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.

### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows Boot Manager SSZ(on /dev/nvme0n1p1)' --class windows --class os $menuentry_id_option 'osprober-efi-DAF7-1754' {
savedefault
insmod part_gpt
insmod fat
search --no-floppy --fs-uuid --set=root DAF7-1754
chainloader /EFI/Microsoft/bootmgfw.efi
}
set timeout_style=menu
if [ "${timeout}" = 0 ]; then
set timeout=10
fi
### END /etc/grub.d/30_os-prober ###

 

 

6 - Save 27_ssz_custom and:

sudo update-grub

7 - On bios Disable Secure Boot (I'm not sure if it is needed)

8 - If everything went right, it will boot on mint by default and windows 10 will be another option on grub.

Samsung S32D850T Monitor

November 8th, 2025

I have a Samsung S32D850T monitor with some issues - the power light LED will flash and the monitor will not turn on.  The problem is definitely in the power supply board (confirmed with swapping in a known good board).  Unfortunately, a replacement is not readily accessible.  Below are links about the monitor and board information.
