Anyone konw how to make EISA Partition???
You probably need the EISA utility from your OEM since these are usually recovery partitons.
I have seen some claims that Paragon Hard Disk Manager Pro can do this or at least make a backup of this partition but I have not personally ever tried this.
I prefer a regular smaller 8GB-10GB partition on which I throw a good know clean Acronis image backup and just use that to restore from if ever needed in the future which has Windows along with every program I need installed on there and registered with all small tweaks here all personalized to my liking… works like a charm and has saved my butt quite a few times as well.
