Hello I read much news but didn't find a solution on a dual boot problem. I did the following: from two old disk, one with XP and the other with Win7 , I made with the help of Matrium Reflex two image backup. Both OS was installed on the first partition. Restored the images on a new external HD (USB). Fist Win7 and WinXP on a second partition. Removed all hard disk's and installed the external disk inside the PC. Started the PC. To start Win7, I have had to use the repair CD from Win7 for the first time. Download EasyBCD 2.2 to create a dual boot to start XP on the second partition. I see this this partition from Win7 and all files. Mapped to G: from win7 But WinXP won't start. I get the error : <Root windows>\system32\ntoskrnl.exe is missing. I think the problem must be that WinXP was installed on the first partition on the old HD. My question: it is possible to resolve this problem with the help of EasyBCD? Many thanks for your help. Otto PS: Sorry for my poor english.
