Hi [NAME],   Most probably Ubuntu 16.04 kernel does not contain PERC H750 driver, hence 16.04 unable to support H740. Refer to the same document that you screened shot, if you refer to page 5, H750 requires version 20.04.2 minimum. You can try using this article to install the HWE kernel but unsure if it works on PERC H750 [URL]   Do let me know if it does. 
I will install PowerEdge R740 with Ubuntu Server 16.04 but the hard disk cannot be detected, I have 2 hard disks with a size of 2 TB. Using raid or not the hard disk is not detected and only my flash disk is detected.  [IMAGE] I've tried installing Ubuntu 16.04 Server with HWE kernel, and using BIOS boot mode but the hard disk is still not detected. In reference [URL] PoweEdge R740 still supported Ubuntu Server 16.04: [IMAGE] I've tried the three versions above but the result is still the same. Has anyone experienced the same problem or knows a solution? I have to install it on Ubuntu Server 16.04 because the service that my application uses is maximum using Ubuntu Server 16.04.Thank You.
