Reset Partition Table for Nexus 7 2013 (Flo)

To cut a long story short I wanted to make the system partition larger on my tablet PC as it's far too small to do anything practical on. I used ADB push to put Parted into the root directory and proceeded to resize some of the partitions, but it has failed terribly to the point I have bricked my tablet. I have luckily enough found some guides on the internet to after I got QHUSB_BULK in Windows Devivce Manager. At the moment I have managed to execute the command fastboot boot twrp-3.2.3-0-flo.img but this is temporarily running from RAM as I'm unable to flash any of the partitions as they are "missing". This is the my original partition table:- https://pastebin.com/rhhjZtef From some reading on the internet Linux can only have 4 primary partitons. I'm no expert in Linux. I know some basics but partitions is out of my area of expertise. All I know is that I have 30 partitions that I need to re-create and I don't know what partition type to set them to; primary, logical or extended. I've played around with the three partition types but I get an error message saying "Too many primary partitions". Could someone shine some light here please? Many thanks Will
