dell latitude 5580 not show usb in bios

It won't show in UEFI setup.  With it connected, press F12 a few times and select it from the boot menu.

If it doesn't show there, was it correctly prepared (preferably using the MS Media Creation tool)?

@ejn63​  i made the usb stick with rufus 

what is the reason bios dont see the stick ?

By default, UEFI does not boot from an external device (which is the reason for the boot manager that F12 allows).

If the boot menu doesn't see the drive as bootable, it's not prepared with UEFI compliance.  You can do this with Rufus, or you can use the MS Media Creation tool to do the job.

@ejn63​ in the link you send me about rufus some say that the usb moest be fat32 en others say that it must be formated ntfs what is the correct way ?

Thats normal that in uefi mode windows boot manager 

Technically FAT32, but that supports Windows install images only up to 4G in size -- practically speaking it needs to be NTFS, since anything Windows 10 and up will be larger than that.

@ejn63​ the win11 iso is 7gb i have formated first as fat32 but rufus automatic changed it to ntfs 

Rufus can be temperamental with UEFI -- use the MS Media Creation Tool, which will work.

@ejn63​ no mate i did usb with mediacreation tool but stil dont show in boot menu damn

Since this system does not have a CPU that supports Windows 11, you will need to use a CPU check bypass to get Windows 11 to install -- a default ISO/installer for Windows 11 will sense the unsupported CPU and halt the installation.

@ ejn63 i have already installed 100 laptop that are " to old" for win11 with a modifed win11 iso 

its the bios that not reconise the usb stick windows have not started yet so i dont think thats the reason why the bios not reconise the stick

Have you tried a different USB port and a different flash drive?

@ejn63​ yes my friend i tryd all ausbports and i have used 5 different usb stick with rufus media creation tool win11 iso win10 iso even ubuntu and a tiny linux live usb nothing works i think the ports dont work because some usb stick have a smal led light and that dont works when i put the stick in the port

If so, the mainboard needs to be replaced, or you'll need to put an install image on the SSD or hard drive and use it to do the installation.  

Bear in mind the system is worth about $100 before you commit to a mainboard replacement.

@ejn63​ its from a friend of me the laptop it work perfect with win10 on and he tryd to put win11 on and then he gets the tmp device not detected so i am almost sure the usb ports also workd the dell support is al very nice and good so long your service tag is ok once its over you must pay to have a chat with someone 

and ok the forums are also good but their are so many peopel with a problem lol
