Let’s see how to solve a particular problem, changing mother board and find no IDE connections, losing a hard drive with the boot sector, partition of /boot, and the CD–DVDs, but trying to keep the other hard disks and the system as it was.
Like all devices one day one of our computers fall down. The heat of summer can be a good reason for this. If the motherboard is very old, we will have to change: motherboard, processor and memory. The problem is that the new mother boards are usually not lead connections to IDE disks but only for SATA. If DVD drive is IDE we can not do all this from a bootable CD, although we could create a USB stick, this time we will not do so.
