Problem with bittboy 3.5 cfw installation

[o_chen]

Hello.
I have 2 sd card for my bittboy. I tried to install cfw on my new sd card (A) using guide here https://github.com/TriForceX/MiyooCFW/wiki/Custom-Firmware-Setup . But after finished writing .img to sd card, there's no 'main' partition to put the game rom

And now, my computer doesn't detect "main" partition on my current sd card (B) that i use on bittboy, after the installation. I can still play game normally, but don't know how to access main partition to add new game. Previously, i can access it and see other partition. But now, they doesn't appear.

I use windows 10

Please help

You may need to assign a drive letter to the main partition so Windows can find it. You can use Mini Tool Partition Wizard to do this. Right click on the main partition and assign a drive to it.
