Hi, You don't say what operating system you are using so this will be for Win98SE. Should be about the same for others. I have several versions of MaxBlast and have cloned many drives with no proplems. On one occasion, for unknown reason, MaxBlast did not move the "Operating System". This does not refer to the whole of Windows, just the files necessary for booting. If you have a startup disk for the Windows you are using, boot from the startup disk and type from the A:> prompt "sys c:" and enter. That will load the necessary files. Hope this helps. Luck, Jim
EDIT: True, newer Maxblasts only work on Maxtor drives. Older ones, up to about version 1.01 and maybe later, work on all drives. If I remember correctly the time that Maxblast did not move the OS files was when the new drive was setup as slave for the cloning. Slaves don't normally have to boot so the files are not necessary. My original suggestion still stands. More Luck, Jim
