    Bought recently SSD Vertex 40gb to put my system on it and leave my old Maxtor 250gb for the rest of my files. So I cloned my system partition (Win 7 64 bit) with Easus Disk Copy, was surprised how quick it was. The problem is I can't make the cloned partition bootable. I thought rebuilding bcd on new disk would be enough but no luck. I disconnected the old drive, made sure bios settings were correct, booted from Win dvd, tried fixboot, then rebuildbcd, but still getting "disk read error". I've read many different opinions on the subject, also saying it is not possible to make cloned OS partition bootable. Any advice much appreciated.

    I would boot from the Win7 media and see if it can see the cloned OS and it should offer the option to repair it. In which case, the boot files should be re-written to cope with any partition changes that may have occured.

    That's what I've done in a first place, Win dvd detected OS installation and automatically "repaired" it but the partition still doesn't boot.

    In which case, a fresh install seems to be the way forward :rolleyes:

    Might be worth booting with a GParted Live disk and double checking that the boot partition is set to active?

    Before you did anything I would use a Windows 7 disk, run a command prompt, run diskpart and check the drive that way, it could be that all you need to do is do an 'active' on the drive and that's it sorted.

    I did this as well, first formatted, made primary partition and marked as active within Windows, then booted from Win 7 dvd, went to command prompt, marked active with Diskpart, tried fixboot, fixmbr and rebuildbcd but no luck.
    I guess fresh install will be unavoidable...:rolleyes:

    Why not use a different product? You could image the current Windows install then image that to the new drive.

    The Acronis trial versions are fully functional, give that a shot, re-image it as Sparky suggests.

    I ended up doing fresh install on my new disk, imaging the old OS partition using Acronis (trial) and copying the image to the new disk. Everything is working fine and booting time is much much shorter:biggrin Thank you for all your replies.
