and thanks for answering, so you mean windows recognizes where it was installed by leaving a "mark" on the motherboard right?
Not a mark on motherboard!
An OEM license belongs to that type of computer. Chipset, cpu, etc. You can't use an image of another computer anyway! Most of the times it work (in 95% of cases). For example if you buy a new computer and restore the image to it. But only if Windows 7 understands it. It has totally different hardware so Windows 7 is confused and has to remove drivers and install new ones. If Windows 7 boots it can be fixed easily.
Most important is the sata driver. The standard Windows 7 sata driver works always.
Once again please post screen of disk management.
Assume you have 3 computers in house to backup. Total used space 800GB in total. Backup will be 600GB (compression). Buy a 1TB external usb disk. (or even larger)
Put backups in Q:\backups\pc1 and Q:\backups\pc2 and Q:\backups\pc3
in pc1 you put backup of pc1. Q is drive letter of usb drive...just an example of course. That letter is different and may vary on each machine!
