USB device Boot

[Arveno Santoro]

Hello,
I have the following problem.
After I have connected an external USB disk to a Proliant ML 150 g5 to make a backup, the system don't make anymore boot from HD, also when the USB disk is disconnected.

I must press F7 key and choose SCSI to make a correctly boot.

In the bios the boot order is correct.

Can someone tell me the voice in bios to disable boot from USB device?
Or give me the link to bios manual?

Thanks in advance.
Best regards.

The solution of problem is:
don't use USB disk for data backup.

The technical support told me to do not make backup on external usb hdd because there are not compatible usb disks with HP servers and the use of this support can make serious problems on servers.

To boot from HDD I had to clear CMOS and now I am able to correctly boot.

Sorry for my little english.

Bye.
