I installed XP Pro on my new computer with a IDE-1 160GB drive and a SATA 120BG dive. The Windows was installed on the SATA drive which for some reason had a letter E: as its designation. Each of the hard drives has multiple partitions. All was working nicely until I noticed that the 160GB drive was only reading 131BG. I used Western Digital Data Lifeguard tool to enable the full 160GB on the IDE-1 drive. In the process I had to delete the only live partition on that drive and create new ones. Well, what that did, is bumped the letter of the boot drive down from E:\ to D:\. And now the computer does not boot! I can boot with the Win XP CD, I can run repair, restore and upgrade, but whatever I do, in the end, I cannot boot because the computer says it can't find a bootable device. Incidentally, when I run a repair facility from Windows CD, it displays--correctly, that a boot sector exists on D:\Windows. When I restart the OS, it can't find it though. Help!!! Any ideas appreciated. Much Thanks!!!

Check the bios settings I mean the setup Check the boot sequence whether d is there or is an option to boot from. Good luck
