i have a server with a ga-ma790ftx-upd5 motherbaord. its OS boots from a flash drive set up with syslinux. i decided to try different software on a different flash drive but when i try to boot of it, after the mobo verifies the dmi pool is says "invalid partition table". the strange part is it boots just fine in another machine. ive tried setting up the flash drive again but have determined that there is nothing wrong with it. it has to be a mobo thing. anyone got any ideas? i updated the bios and the "legacy usb boot" option is enable and set to boot from usb-hdd.
