Xfce windows 10 dual boot (wifi & unable to boot into windows issues)

Support
#1

I successfully installed xfce 20.2 on a hp 15 laptop with windows 10.

Issue 1- wifi connection not visible or working.

Issue 2- As a potential solution, I attempted to boot windows to disable fast startup/hypernation AND I was unable to boot windows

Issue 3- In attempting to show windows as a booting option, I created a .cfg file with the following contents:

menuentry “Windows (UEFI)” }
search --set=root --file /EFI/Microsoft/Boot/bootmgfw.efi
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}

AND when I rebooted I simply got a black screen. Stuck and not sure what to do now.

HALP!

Hello :slightly_smiling_face:!
One question for clarification: Are you still able to boot Windows 10 through your BIOS/UEFI right now?
If not, you might need to repair your Windows Boot Manager.
I’d also advise you to never change grub.cfg by hand as it is very dangerous and may in some cases like yours brick your linux install.

For the future: how to properly add a Windows10 boot menu entry in Manjaro

No warranty!
A better solution to detect Windows 10 would be to edit the file

/etc/default/grub

and set

  • GRUB_TIMEOUT=5
  • GRUB_TIMEOUT_STYLE=menu
  • GRUB_DISABLE_OS_PROBER=false

Make sure all parameters are uncommented
Afterwards, you need to run sudo pacman -Syu os-prober && sudo update-grub

In any case, could you boot up a Manjaro Live USB/DVD and post the output of the commands

inxi -Fxzc0

and

sudo fdisk -l

?
This would help us troubleshoot your system.
