Hello,
After installing MX 23.6 on my PC, Windows disappeared from the boot menu.
I have only MX 23.6 as boot option.
Here is the output from the lsblk -f command of my PC:

It would be nice if somebody could help me to add Win to the bootmenu.
In any case I enjoy a lot using MX Linux, but I have some Win applications I want to use.
Best regards,
Marcel

Post QSI "Quick System Info" to be found within the menu or with the MX Welcom Screen , so we know what system is involved.
Also do post text output of commands within as code-block, so it is better readable. use [</>]tag button with the full post editor.
You can edit you first post an enclose/wrapp the lsblk out put into a code-block

OK, power off. Wait some seconds. Power on and hold the Fn-key to boot into th UEFI-boot options list
I think it is F12 (?) maye another key. Normally you see the key mentioned at the bottom of the screen during POST (power up)
Within the UEFI Boot options list select Windows ... .
If you can't boot into UEFI-boot optiion list, use MX LiveUSB
and select boot at LiveBoot menu -> Boot Rescue -> search for "efi loader"
(or maybe it was a separate entry for "window efi loader" ...).
When booted into windows, disabled fast-startup, or hold the Shift key when selecting power off.
Or create a Windows shortcut Icon with:
Code: Select all
name: Full Shutdown
command: shutdown /s /t 0
When done re-start (power off and start again) into MX Linux and recreate GRUB menu with:
Does it find Windows? Will the generated entry boot into Windows?

Hi fehlix, i tried everything, I can go to the BIOS boot menu but it is impossible to boot Windows. I also tried to boot from a USB Stick but that didn't help.
At one point I got an error: Secure boot violation but I could change the setting in the BIOS to deactivate the secure boot and then the MX Linux boot menu came again....uff!
I also saw the BIOS boot menu while pressing the F8 button, but independently of the different boot choices I could only boot MX Linux from the disk and not from the USB Live Disk.
Any idea what I could try else?
Thanx in advance...

Not sure what you done, "at one point" doesn't tell me much.
Your QSI above shows you have not booted with secureboot, Ohterwise QSI would show "Secureboot enabled".
So why suddently you have a secureboot violation which is only after you have enabled secureboot.

I don't know what a "BIOS boot menu" is, you may mean "UEFI boot options" list?
Anything else you have "adjusted somewhere"?
And are you saying Windows does not boot from "UEFI boot options" list w/ or w/o secureboot?

Not sure I understand. Are you saying you can not boot anymore from MX LiveUSB. Otherwise be a bit more spelled out.
You can only boot the install MX Linux through LiveBoot Rescure menu with disabled secureboot.
When you say something like "cannot boot" what does it mean? Not errors only blank black screen?
Does the rescue menu not find anymore any grub*.efi files? Or it does, but when select what happens ? No errrors?
Or does the MX GRUB menu shows up but no further boot will work etc pp. Please explain bit more.
Also, When you select search fro GRUB cfg menu files, what happens here.

Boot into MX Linux, run "UEFI Manager" and add the /EFI/Microsoft/Boot/bootmgfw.efi as a new entry.
Which may be show up with UEFI Boot Options list.

After installing MX 23.6 on my PC, Windows disappeared from the boot menu.
Also what does this mean? What boot menu was it, before installing MX Linux.
I mean WIndows normally offers not a boot menu.

I also think that we need to know what install method you used.

I don't know how to upload the pictures I took, so I will try to explain in more details.
1) Pressing F8 Key during start up:
An ugly Boot menu appeared with the following choices:
a. Windows Boot Manager: (P1: SanDisk SSD Plus 480GB)
b. MX Linux (P1: SanDisk SSD Plus 480GB)
c. MX23 (P1: SanDisk SSD Plus 480GB)
d. UEFI : JetFlash Transcend 16GB 1.00 (this is my USB Stick with the MX Live Boot image)
e. Enter setup
Independently what I choose, a-d, the LINUX MX Boot menu appears.
Only choice e, brings me to the BIOS setup menu of my PC
2) after entering the BIOS setup menu of my PC, I go to the Boot - Menu.
There I have the following choices:
a Bootup NumLock State =[On]
b Quiet Boot [Disabled]
c Set Boot Priority:
option 1: USB Key: UEFI: JetFlash
option 2: USB Hard disk
option 3 Harddisk: Windows Boot
Note: I can change the ordering, but the boot behavior is the same,nothing changes, (I also opened the PC, changed the CR2032 battery..._)
d UEFI Hard Disk Drive BBS Priorities
option 1: Windows Boot Manager
option 2: MX23
option 3: MX Linux
option 4: UEFI OS (P1 Sandisk)
e UEFI USB Key Drive BBS Priorities
option 1: UEFI: JetFlash
I hope this helps...

I have done a new USB Boot stick with the Ventoy tool on another computer and I could successfully boot with that stick.
After booting with the MX LiveUSB stick I select Boot Rescue and then "Boot Rescue Menus".
Then I have the following options:
a. GRUB EFI bootloader
b. GRUB menus
c. Frugual menus
d. Windows bootloader
e. Reboot
f. Power Off
g. Reboot into BIOS/UEFI Setup
After choosing the d option, I get the message "No Windows bootloader found."
Any idea what I can do next?
Thanx in advance for your help!

First question, when you select find "a GRUB EFI bootloader", will it find "MX Linux" efi's and would it boot into MX,
This is just to make sure your Ventoy setup works?
Next, let's see what the ESP and UEFI-NVRAM looks like.
Boot normally into the installed MX Linux:
Now run below commands which gives terminal text output.
Do copy the commands and the text output and paste here in the form within code-block tags like this example looks like: [
code]paste text here[/code
].
And do paste for each command + text output separately:
Open terminal as normal user:
First post again slightly modified partition layout including part-uuid:
Next, have a look into the NVRAM to get the UEFI entries:
both above may help to see what's wrong.
Now the command to see the efi-files on the ESP:
Maybe there is something out of order with the win-efi files.

Good evening fehlix,
Hi.
So what about my first question within my last post?

Hi had to reboot for answering your first question.
It looks like this:
====> EFI Bootloader <=====
boot @[fat] (hd1,2)/EFI/boot/bootx64.efi
Boot @[fat] (hd3,2)/EFI/boot/bootx64.efi
mx @[fat] (hd3,2)/EFI/mx23/grubx64.efi
mx23 @[fat] (hd3,2)/EFI/mx23/grubx64.efi
rootMX23 @[ext](hd3,5)/boot/grub/x86_64-efi/grub.efi

..and yes, if I select the last entry, the MX Boot menu appears and I boot from my harddrive...

OK, those 4 entries are related to the installed MX Linux::
Code: Select all
====> EFI Bootloader <=====
Boot @[fat] (hd3,2)/EFI/boot/bootx64.efi
mx @[fat] (hd3,2)/EFI/mx23/grubx64.efi
mx23 @[fat] (hd3,2)/EFI/mx23/grubx64.efi
rootMX23 @[ext](hd3,5)/boot/grub/x86_64-efi/grub.efi
The last one is on the root-partition "rootMX23", which boots- so you have good fallback.
The other three are on the internal ESP on /dev/sda2.
Please try also all other three. This may help to give indication about the "health" of the ESP.
Do ignore the first entry :
Code: Select all
boot @[fat] (hd1,2)/EFI/boot/bootx64.efi
, that's probably the ESP on the ventoy USB-stick.

With all three the MX Linux Boot menu appears, exactly as with the last one. I just booted from there my system...

OK, mayb the ESP is not completely corrupt:
On the ESP the find command lists three efi files related to Windows and some input/output errrors:
Code: Select all
176 159 -rw-rw-r-- 1 root root 162192 Jan 26 11:43 /boot/efi/EFI/Microsoft/Boot/SecureBootRecovery.efi
310 1344 -rw-rw-r-- 1 root root 1376240 Jan 26 11:43 /boot/efi/EFI/Microsoft/Boot/memtest.efi
find: ‘/boot/efi/EFI/Microsoft/Boot/pl-PL’: Eingabe-/Ausgabefehler
find: ‘/boot/efi/EFI/Microsoft/Boot/pt-BR’: Eingabe-/Ausgabefehler
But the efi-file bootmgfw.efi is missing. This bootmgfw.efi is needed to boot into windows, and would look on the esp like this:
Code: Select all
/boot/efi/EFI/Microsoft/Boot/bootmgfw.efi
indicated also within NVRAM entry as such::
Code: Select all
Boot0000* Windows Boot Manager HD(2,GPT,9054db71-437d-40c1-954d-5551f76d817b,0x109000,0x31800)/File(\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI)WINDOWS
So looks like somehow the ESP is corrupt.
To fix;
Boot a recent Windows or WInd Recovery DVD and naviagate within the DVD-Boot menu to the place
where you can re-create the ESP/EFI for windows.
Windows may recreate the ESP or may just add the missing files.
You would always have a backup by using the Live-Boot Rescue menu to boot into MX.
When the Win ESP is working, power off from windows with holding Shift-Key when clicking on power-off
or disable windows fast-startup permanently.
When booted into MX, recreate the boot menu with:
Good luck.

noursle,
This may be of value (or not). At times I've had to reinstall and the Windows menu has disappeared. What I have found success in is boot into MX. Grab from mxpi if you haven't already got it installed, Grub Customizer. Run GC and you very well may find (as I've done) the errant Windows menu. Good luck if the later suggestions in this thread don't solve your problem.

Grub Customizer can't customize what isn't there. Just sayin.

So, after 2 hours I gave it up to reinstall WIN ESP.
I followed the instructions I found on the internet, but I fail at the last step:
1) Boot with Win USB-Stick
2) Repair your Computer
3) Troubleshoot
4) Command prompt
5) diskpart
6) list disk
7) sel disk 1
list part
9) sel part 1 (Fat partition SYSTEM)
10) assign letter=y
11) exit
12) format y: /fs:FAT32
13) bcdboot c:\windows /s y: /f UEFI
and here I get the error message: "Failure when attempting to copy boot files."
I restarted my PC with the MX Boot-USB Stick and recreated with the MX-BOOT-Reparatur the MX-LINUX BOOT menu.
And here I am again...long live MX LINUX!!

This means your choice of the drive letter C:\Windows was incorrect. Yes, it is the main drive letter when Windows boots normally.
What was likely not clear in the directions you were following as to how to identify the Windows main 'drive' for bcdboot.
Look for a volume of 48 Gb to 62 Gb in size (or more) as that will be it. BTW you don't have to use C as the drive letter, it can be any letter other than y and will work fine.

The diskpart utility can be really beneficial here. Not only does diskpart have the power to perform the format action directly ("format fs=fat32 quick") but after assigning a letter to the EFI partition one can also list all volumes on the disk ("list volume" or "list vol"). This is an easy way to figure out where things are in a Windows rescue session and pinpoint where common drives like C:, D:, and X: ended up being put.
It can take a little guesswork if you've partitioned the disk in a unique way ("I want a 50 GB Windows partition and a 50 GB data partition on the same disk") and has to be done for every disk in the machine because diskpart only inspects one disk at a time, but for most users who follow Windows setup best practices, you'll only have one OS Disk and only a couple of partitions on it. Giving your Windows volumes sensible labels ahead of time can also help identify them later.

Dear all,
many thanks, I could reinstall a correct Windows-EFI Boot Partition after changing the letter to E: instead of C:.
I could find the correct partition name with the diskpart command: "list vol".
Then I have done an "exit" from the diskpart-tool, changed to E: and checked with "dir" if I could find the Windows directory.
And yes, there it was!
(y: is my empty boot partition, see step 10 from post #22)
Back to "X:\source" and then I entered the command: "bcdboot E:\windows /s y: /f UEFI"
and voilà, no error code and the EFI Boot Partition could be created.
I restarted my PC and I could boot to Windows (since end of january 2025).
After running the Windows updates, I made a Shortcut "Shutdown.bat" with the following code: "shutdown /s /t 0" and clicked on it.
Then I restarted my PC with the MX-Linux Boot stick, bootet my MX-Linux and opened a terminal and entered the following command:
"sudo update-grub"
Then I restarted my PC, clicking the F8-button (on my PC, on yours it could be F-12) to enter the UEFI bootmenu.
There I was able to select an entry to start WIN or MX-Linux.
I learned a lot of your all, many thanks!
This issue can now be closed.
