Question: I am trying to install Windows 2008 server on a HP Proliant DL180 G5. There is no built-in DVD reader so I need to use my LaCie USB one.

When I put the CD in and boot from the USB DVD on the server, I get the error message:

Boot Failed! Please insert boot media in selected boot device.

So I tried with another Windows bootable CD and still no luck.

What I've done then, I copied the installation DVD on my 16go USB key. Again, impossible to boot from the USB Key. 

I have 2 147go SAS 15k HDD on my server. They are not showing in the Bios. I was wondering if this is a reason why nothing will boot on it.

I am trying to find a way to deploy Windows 2008 server on my HP server as soon as possible.

If you guys have ideas, feel free to let me know :)

Best regards,
David.

System Information:
HP Proliant DL180 G5
Quad-Core 2.5
4GO Ram 
2x 147GO SAS 15k

P.S. This is my first installation ever on SAS/SCSI HDD.

Thanks a bunch!

Edit:

Well, my bad! I purchased a new USB DVD and now I can install Windows 2008 server.

Thanks a bunch for your help!

Answer: 
You'll probably need to go into the BIOS and enable it to boot off the USB drive.
You need to make the USB key bootable first. 

You can do this by following these steps:  

--please note that this process will format the USB key  

1. Open a command prompt (an administrator command prompt if using Vista/Win7/Server 2008)  

2. enter diskpart by typing in the following command: diskpart  

3. find out which disk is the USB key by entering: list disk  

4. note the disk number of the USB key (we'll use [diskNumber] as a placeholder in the next step)  

5. select disk [diskNumber]  

6. clean  

7. create partition primary  

8. select partition 1  

9. active  

10. format fs=fat32  

11. assign  

12. exit 

Copy the files from the installation media to the USB key and you should be good to go.
