I have a Dell OPTIPLEX 755 PC at work. It has a Crucial M225 SSD in it used for the OS and other programs. Currently it has firmware 1916. I'd like to flash it up to the latest firmware (2030).
However, when I go into the BIOS and turn ACHI off, the BIOS then fails to recognize the HDDs in the boot priority section. When I try to boot from CD (an iso image of the 2030 firmware) it doesn't recognize it and defaults back to the SSD and Windows starts.
Any ideas?
I've burnt the iso image using a CD-RW. Could this be the issue? Can you boot from a CD-RW or is there something about the formatting of this that prevents it?
Thanks in advance.
