Ok, I'd like to start by saying that I have read MANY posts in this forum related to the problem I'm having, but each post I read seems to have one little variable that doesn't pertain to my situation. I've read many great posts from Brian K and MudCrab etc, but I'm hoping there is one good solution I need to go with here. My problem is the inability to boot into an OS after cloning. Here's the deal: I'd like to start by saying that my laptop is dual boot. I have Windows Vista Ultimate on my C: partition, data on my D: partition, and Windows XP Pro on my E: partition. I use a free app called VistaBoot Pro which gives me the choice of which OS to boot into when I start up the pc. The screen to choose the OS comes up right after the laptop's splash screen. All the Vista Boot Pro info, and boot files are on the C: partition. Also, there a small 4GB "hidden" recovery partition that came with the laptop. This recovery partition has Vista recovery on it since Vista is what came with the laptop. I have no idea whether any of the above information causes any additional problems to what issues people are having with just cloning a single OS hard drive. So anyway, I tried to clone this original 80gb SATA drive to my new WD 160gb SATA drive. I did this by putting the new drive into a USB enclosure. I run TI 10 (build 4942 I think... the latest one) from within XP. I did manual clone mode, kept the data in my old drive intact, and chose proportional allocation. The process finishes successfully (although when it tells me to press any key to shutdown, no key will shut it down. I have to eventually press the power key). So I remove the old hard drive from the laptop, replace it with the new one that was in the enclosure, and turn on the laptop. I do get the screen where I can choose my OS (I thought I was successful) but ALAS, if I choose XP, I get the NTLDR error. If I choose Vista, I get the Vista error (winlog.exe if I recall??) Shoot. I put the old harddrive back in... everything is fine, boots up normally. Attempt #2 - format the new drive, and try again but this time using TI from within Vista instead of XP. Should that even make a difference? Probably not, but just trying anyway. Same result. Finally, I tried, based on reading some threads, to create a bootable rescue media CD and do it from within there. Only problem there is when I try to boot into Acronis with the boot CD, it hangs on my onboard audio (Realtek HD) and will not go any further. So, there you have my issue. Right now I have the new HD sitting here, ready to reformat it for the 4th time to try something else, but before I do that, is there something I should try to fix the boot issue? Any implications of the fact I have two OS's on there? I've read so many things to try to fix the boot issue, I don't know where to start! I did look at the boot.ini file and it says that it boots WinXP from Partition 3, and sure enough, XP is on Partition 3 on the new drive, but still get the NTLDR error. Please help! By the way, I have no idea if this will help, but I have two other pc's available to me and several USB enclosures if anyone thinks I should try hooking both drives up to an entirely different pc. I would think no because we wouldn't want the other pc to assign any drive letters to the drives, but, what if I did it with the acronis boot disk? (which WILL work on my other PC's) Thanks everyone!!!
