Hi @Nizar6 

probably the disk is damaged, when turning on the device press the F2 key several times, test the disk and see if it passes or gives a failure ID.

I tried 3 different disks witch when diagnosed give no errors

When I try to execute my bootable usb on any hdd it gives me an error that sais could not locate target partition

the USB that you create has the windows operating system to be installed on the disk ?

[Nizar6]

Yeah i used rufus to format it with windows 10

Leave only the installation disk, remove the other disks and then delete all partitions and install windows on the remaining partition.

I recommend using Microsoft's media creation tool.

Ok use RUFU , but leave only the installation disk, remove the other disks and then delete all partitions and install windows on the remaining partition.
