Thanks jaclaz for pointing that for me and realize that they both refer to same root, and excuse me for i am new to all these usb stuff . root (hd0,0) kernel /syslinux/vmlinuz0 ro rootfstype=msdos root=/dev/sdb1 quiet liveimg rhgb initrd /syslinux/initrd0.img ilko i did not get your drift, did you mean to create a folder in my root named fedora and then change the entry or what. and for the the knowledge what do these enteries(hd0,1)and (hd1,1) refer to.
