Can't boot to USB device on Precision T7500
I have a Precision T7500 running Win 7 64bit.
I wanted to restore to an image held on my Windows Server 2012 Essentials machine.
The procedure involves booting to a USB stick that is created on the server. However when
I use F12 at post to select the USB device, the bios tells me there is no USB device available.
This is true for the front USB ports, and one of the rear ones (I tried several times).
I have the A14 bios, and the 15 and 16 revisions do not seem to have anything to do with this.
Any ideas? Can I somehow convert the USB stick to a bootable DVD? I know the T7500 boots to
CD.
Thanks,
Andrew

Are you connecting the USB device before powering the system on?
Have you looked in BIOS setup to see if there's an option to allow booting from USB, and that it's enabled?
Try putting USB as first boot device in BIOS boot sequence instead of or in addition to selecting USB from the F12 menu.

All USB ports are enabled as should and USB is the first boot dev. in the list. I plug the SanDisk USB stick in the front (tried both front USB ports) and power on the system. USB stick gets powered (its green LED turns on) but system still doesn't boot from the USB.
When I use F12 boot menu BIOS powers the USB (green LED turns on) but at this point BIOS doesn't recognize the USB stick as a drive/disk. My old Asus lists the USB stick on its boot menu by name "SanDisk USB drive".
I run latest Dell T7500 BIOS - A16.

All USB ports are enabled as should and USB is the first boot dev. in the list. Yes, but is there a separate option to allow booting from USB? (The online manual doesn't show BIOS screens so I can't see them.)

There isn't a separate option to boot from USB. There are only three USB options; "Disable", "Enable", and "Do Not Boot". "Enable" is selected.

Same issue. I have DOS USB drive that boots just fine on my old Asus but does not on the Dell T7500. Did you find any solution?
