When trying to install from ISO I was forced to use the basic graphics option in the troubleshooting menu. I discovered that the kernel options appended in the isolinux.cfg specify the wrong disk label.
See here the correct append parameter. Specifically the \x203\x20 in the label
label linux
menu label ^Install Rockstor
menu default
kernel vmlinuz
append initrd=initrd.img inst.stage2=hd:LABEL=Rockstor\x203\x20x86_64 quiet ip=dhcp ks=hd:LABEL=Rockstor\x203\x20x86_64:/ks.cfg
Then in grub troubleshooting menu both the vesa plus the rescue install have \x203.0\x20 and the correct label is simply 3 not 3.0
label vesa
menu indent count 5
menu label Install Rockstor 3.0 in ^basic graphics mode
text help
Try this option out if you're having trouble installing
Rockstor 3.0.
