Hi all, I hope some clever bod out there can help - I don't know what I'm doing so consequently am not getting too far. I have a PC with a hard disk that has 3 partitions - Windows 7, WinXP and documents. Each partition was getting a little full so I want to upgrade it. I bought a 1Tb drive, installed and partitioned. Cloned the drives across. All looking good. I now had 2 drives and 6 partitions - Drive letters from C to H (DVD drive unplugged at the mo). C,D.and E are the old drive and F,G and H are the new drive. I unplugged the old drive and re-started the machine and got an "NTLDR missing" error. Plugged the old drive back in again and all works on the old system. Did some scratching round and found that I had to copy some system files across to the new boot drive. When I investigated further I found the systems files were (for some odd reason) on drive E. I've copied boot.ini, bootmgr, NTDETECT.COM and ntldt over from drive E to drive F. I unplugged the old drive again and now it's complaining about changes of hardware and software. I'm guessing that I could be looking for a boot drive (maybe E) that no longer exists because it's labelled differently (F). I may have to edit bootmgr?? My worry is that the Disk Management window looks subtly different and I may have set things up incorrectly. Before I go to far down a dangerous path I wonder if anyone would have a look and give me some wisdom? I attach a picture of my Disk Manager (from Win 7) - I hope you'll be able to see what I mean. Bob PS - Actually this is my sons computer and I'm his dad trying to help but worried about messing it up for him!
