T40 dell no bootable devices found

Siol, 

I would start with checking the USB Boot Support is still enabled in the BIOS, under USB config,  as well as checking the boot order under Boot Sequence.

Let me know what you see.

I too get the same issue.  Could you please provide solution?

Hi,

Before installing the OS you have to boot to the SMTD media that will prepare the OS installaton with the PERC driver required.

Here is the related documentation : https://www.dell.com/support/manuals/en-us/poweredge-t40/pet40_ism_pub/options-to-install-the-operating-system?guid=guid-db302b10-5a20-4cdf-863c-d3a31758f970&lang=en-us

Regards,

Siol,

I had the same problem. I bought the T40 on Black Friday 2020. As a student, I installed Windows Server 2019, Windows 10, even Ubuntu Linux. However, I was not able to get the unit to recognize the hard drive as a boot device. I salvaged an older computer to run Windows Server and Hyper-V. Last month, I began studying in a Unix class. I came across a Linux distribution called Rescatux which diagnoses a system from a USB drive boot. I was curious, so I pulled the T40 out of storage and installed it. When the installation prompted me to remove the storage media and reboot, my expectations were rather low. I was astonished to see it boot from the hard drive. I do not understand precisely how it worked, but I was delighted to see my $400 Black Friday science project functioning. It is now running Ubuntu Server, administered via Cockpit, as a headless file server. I hope this might help you.
