Hi Folks, I'm posting this to illustrate how I replaced\removed XP from my system in favor of Win 7. First some background. I've been using Win 7 since the beta as part of a multiboot setup on my Acer laptop. The other MS OS was my old XP install. My old XP was located at the physical start of my drive. To install Win 7 beta, the subsequent RC and finally the Win 7 Home Premium retail I simply had created an appropriately sized NTFS partition at the physical end of my HDD. As each release became available I simply performed a clean install to the same partition. I also have 4 Linux distros in the space in between the MS OS's. I've been using the final release of Win 7 for about 9 months now and have been very happy with it. I recently began experiencing minor but annoying issues with Win 7 so I figured it was time for a re-install. Since I haven't used XP much since starting my adventure with Win 7 I decided to jettison XP and recover the disk space. My plan was to ultimately install Win 7 at the start of the drive in place of XP. I knew that the XP install contained the BCD info needed to boot Win 7 so to save time and hair pulling I decided on a safer although somewhat round about way to do this. Here is what I did. I had a spare drive laying around so I partitioned it with 2 NTFS partitions. The first partition created was the same size as the original XP\Win 7 partitions (23069 MB). I did this so I could clone the new install to my drive later. This was because Clonezilla, my prefered imaging program will only restore an image to a partition the same size or larger as the cloned partition. The 2nd partition, actually the rest of the space, I made NTFS also. This partition would be used to install my apps and programs after instaling Win 7 to the first partition. This keeps the Win 7 footprint fairly small, around 10 GB, (having a small footprint makes it easier to create clone images later). I next installed the spare drive into my laptop and installed Win 7 to that first partition. Several Windows updates later I was ready to install any needed drivers (2 actually) and install my programs and apps. I had previously created a folder on my other NTFS partition to install these programs in. I had named the new folder "Program Files", the same as the default folder in C:\. I then instructed the various program installers to install to the U:\Program Files folder. While I was at it I relocated my C:\user library "special folders" to U:\Program Files. These folders included the My Documents, My pictures etc. libraries. I would later restore the data to these folders from backup. I had a similar arrangement originally but it was a bit haphazard since it evolved over time and had program files from both XP and Win 7. When everything was setup like I wanted I did a disk clean up and defragged C:\. Next, using the Clonezilla Live CD, I created an image of my new Win 7 install saving it to a USB flash drive. Now came the "risky" part. I reinstalled my old drive and manually copied the data\program files from the new drive's U:\Program Files folder to the corresponding folder of my old drive. I used a Hard Drive Dock to transfer the files\data. Next I booted Clonezilla Live and instructed it to restore the image I had created earlier of my new Win 7 install to the partition that contained my old XP install (the first physical partition) thereby replacing XP with my new Win 7 install. When Clonezilla was done I restarted my computer and success, I now had a fresh copy of Win 7 at the physical start of my drive. The Clonezilla operation removed my original boot menu so that I could only access Win 7. I knew this would happen. Popping in my SuperGrub CD and performing a GRUB restore fixed that. I can now boot Win 7 and all my Linux distros like before. The space at the end of the drive taken up by my old Win 7 install I reclaimed by formatting it to ext3 and installing another Linux distro. Everything works great now and the errors are history. The above may sound risky but it really wasn't because I had Clonezilla images of all my original OS's saved just in case. If I had messed up my original drive I could have restored everything in a matter of minutes. As it turned out everything went fine with no issues except for the expected, but easily fixed boot manager issues. In the event I ever need XP again I used Conezilla to restore my last XP image to the C:\partition of the spare drive I used to create my new Win 7 install. I only need swap drives to access XP. I probably will only access it to periodically preform updates. I have a Clonezilla image saved of my new Win 7 install to serve as a base image. The next time I find I need to reinstall Win 7 (because of "software rot" like now) all I need do is restore this image and update it. Total time about 5 hours.
