I tried already several way to create the usb stick.

Usb stick was already running on a different system.

I used Linux app to create new stick windows app.

I used Rufus I used the windows Media create stick I put a 2024MB partition on the stick.

Still only a black screen during boot.

Secureboot sure boot pre dma is all disable.

I did a bios reset to default.

Only disk currently in is windows 11 and Fastfood is disabled.

I would highly appreciate a hint what that could be.

I also clean the secure boot keys.

Thanks in advance.

Does it show the Unraid boot menu or not even that?

Also, post a photo of the BIOS boot menu

No boot menu from unraid.

Just a black screen after the post screen from the bios

I was able to boot into Ubuntu iso via ventoy

I tried three different usb sticks.

Also boot file file not helping.

This is not my first Linux I am trying to boot. No clue why hp makes it so difficult.

Assuming that last option is the flash drive, back it up and then try recreatint it this way:

Get the Unraid zip from https://docs.unraid.net/unraid-os/download_list/

- Open Rufus and change "Boot selection" to "Freedos"

- Set the "Volume label" to UNRAID

- set filesystem to FAT32

- click START

- once done, unpack the Unraid ZIP to the flash drive

If you are booting UEFI nothing else you need to do, if you are booting legacy/CSM, run the make_bootable.bat as administrator first.

If that works, you can then restore the config folder from the previous install.

Tried That with one usb stick. Same behavior. Also tried different unraid versions🙁

Does it boot with a different PC?

It amy also be worth trying with the Limine boot loader, in case the BIOS os not cmpatible with the stock one https://forums.unraid.net/topic/196349-black-screen-after-usb-boot-msi-x870e-carbon-ryzen-9950x-rtx-4070-ti-super/?do=findComment&comment=1607672

Yes stick was booting before on a self build pc without issues.

Wil try other usb sticks updàting bios a.s.o.

Cannot be that I do not get that running..

Also removèd windows ssd in case windows booțloader is blocking

Try the Limine UEFI bootlader, link above.

will give it a try thanks

it is booting with BOOTX64.EFI limine binary

hurrayyyy.

But why??????

Some BIOS, mostly recent AMD board, are incompatible with the stock syslinux bootlader, note that if you create an internal boot problem, it should no longer be an issue, since that uses a different bootloader (Grub)

thanks for your support. need to check about the installation on internal pool.

not yet familiar with this new concept.

Does this solution survive an update?

Or is this efi file never touched?

Yep, only the bz* files and changes.txt are updated.
