I had a Windows 8 Preview USB Installer. It worked well. I wished to make it Live CD for Linux as well, along side, side by side. Now the Live CD Maker/Installer software like Multiboot or Pendrive did install the Live CD, but was it my mistake or the programmers' insight that the previously installed Win 8 bootsect was lost. Need to work on it without destroying data. Need to fix it with command line from syslinux or GRUB or anything other than Windows bootrec or fixmbr methods.
