good night (at least in my country) I just recently booted my bbb with ubuntu with a 16GB sd card (thanks for the help) and it worked great so I decided to install a desktop but I wanted to do it in my sd card, I googled about it and read a tutorial about expanding the file system so I can use the card as a partition. Heres the link

http://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD

The problem is I followed the tutorial step by step but in the end I received the message bad magic number in super-block while trying to open /dev/mmcblk0p2 (the partition identifier) couldn’t find valid filesystem superblock

I tried again and again and always got the same message, maybe I’m doing something wrong so please can someone help me

Thanks again for your help
