The usb flash drive must support booting from it & you should have iso file of linux OS.
Then follow these steps:
- first you have to install “livecd-tools” package.
- now plug in the pen drive & search the node using dmesg command in terminal,then unmount the partition created by it e.g.:umount /dev/sdb1
- now use this command to make it bootable:
livecd-iso-to-disk –format –reset-mbr /home/folder/fedora15_32bit.iso /dev/sdb1
where /home/folder/fedora15_32bit.iso is path,where iso image is present & /dev/sdb1 is path for usb pen drive.
After the terminal shows 100% complete,your usb drive becomes bootable..& this pen drive will no longer show files on windows..
