This problem happens on both an IBM blade & HP blade 

I installed Linux 5.X on my HP blade from a PXE server. Linux installed successfully from the PXE. 

I changed the HP Blade boot order so "hard drive" is before the "PXE NIC" order
so Linux will boot from the hard disk.

Although "hard drive " was before "PXE NIC", HP blade still boots from the PXE and not from the hard disk.

Note I disconnected the PXE LAN and the Linux booted successfully from the hard disk (but I not want to remove the PXE LAN from the blade)

Example of HP boot order after successfully installed linux 

```
 CD-ROM
 Diskette Drive (A:)
 USB DriveKey (C:)
 Hard Drive C: (*)
 PXE NIC 1 (**)

```

example of HP blade boot order before I installed linux (downloading linux from PXE server)

```
   PXE NIC 1 (**)
   CD-ROM
   Diskette Drive (A:)
   USB DriveKey (C:)
   Hard Drive C: (*)

```

Can anyone suggest why this is happening?
