Not on a 7270 but on 5470, 5570 etc. etc. Which client version are you trying to install?
in general, make sure that SATA mode is set to AHCI in the BIOS (Windows will almost certainly need a reinstall if you need to change this) and that you are using the appropriate hotkey options - ideally from a recent POACFG file provided by Sophos. But at the very least, I suggest NOATA=1 as an installation parameter:
I'm trying to install 7.00.2.23 on a Win 7 Pro which was modified by adding the newer SATA storage controller driver which was required to install with this particular Dell model E7270.
The BIOS settings were configured as AHCI and set to Legacy Boot on. I tired running your suggested command line from an elevated command prompt, substituting the z:\02_SGNClient_x64.msi with my location\installer name but nothing appeared to run.
Try removing the /qn from the line above - that will give you the GUI version, modified with the appropriate settings.
Additionally, you could also add some logging options to get some really detailed output that you can send to Sophos for further analysis - see my answer to this post here
