so in a long story involving me unplugging my USB device and hightailing it during system shutdown, it seems my BT3 no longer boots correctly

I reformatted both the FAT and EXT2 partitions and retrieved only my data, replaced the contents of the USB .iso and went through the whole persistent changes stuff and the problem still occurs...only this time, the syslinux.cfg appears blank in linux not in windows.

it stops and gives me a funny error message during startup saying it had a problem with "union" and it should never happen please cntrl+alt+del to restart.

this only happens when I apply the persistent changes.

im confounded... please help
