i have created live media using disk image writer utility on debian based rebellin os
md5sum checked... no problem on booting and on live session ....
i am sorry but i dont know what bios or gpt setup... manjaro or debian based distros can be installed without any problem on my machine ( pentium dual core e5500 cpu and 2 gb of ram - WD hdd )
maybe kaos is not for me... better i chose another distro that works for me...
thanks.
