V90 - no "main partition"

[LookToWinward]

Hey folks, trying to install the new cfw on a v90 for my kid. Using a spare 32gb sandisk sd card I had lying around but now i'm having an issue where the "main" partition isn't showing up on my system. Here's what my partitions look like on partition wizard:

Note: this is my second attempt - originally I tried allowing the boot wizard to automatically expand the "main" partition but then the "main" partition wasn't showing up instead one of the "other" partitions had expanded to fill the space. Example of that here:

Would appreciate some help! Loving how this cfw addresses unsafe shutdowns/the suspend options so I'd like to get this working.

For the 2.0 beta, Windows can't read the main partition natively, because we changed it to a Linux format, that's less likely to get corrupted (BTRFS). However, if you put the SD into the v90 and boot it up and enable MTP mode, you can connect it via USB cable, and windows can read the main partition through the v90. (Also, it automatically expands the partition on the first boot, so you don't need partition wizard.)

Alternatively, you can make a Linux live USB and boot your computer from that and then manage the SD card in Linux.

Here's instructions for how to make a Ubuntu live USB: https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview

(This method can be faster if you have a large rom collection that you're trying to transfer over.)

Perfect - thanks!
