The boot flags can be viewed by pressing F5? F6? (one of those) on the
setup boot screen and then navigating to the boot line with cursor keys
and adding the boot parameter below before the double dash at the end of
the line.
The flag to disable the Hyper-V IDE drivers [ VVM: i.e. hv_storvsc not prefered ata_piix to work with IDE HDD ] is:

ata_piix.prefer_ms_hyperv=0

Detect hard drives:     [O]

but only IDE , not SCSI

P.S.

But _true_ solution is 

add the Hyper-V kernel modules ( as minimum,

hv_vmbus
hv_utils

hv_storvsc
hv_netvsc

)

to initramfs of installer .ISO
