HI,On my new PC : WINDOWS 7 64bit, 3 HHD are installed 2x 500G SATA and my old 250G IDE.The 100Mo has been installed on D disk and the start part and OS is on C disk.For me it's a problem because i wanted my D disk to be a backup, if i lost the D disk every thing is lost : the backup and system to.Is it possible to move this system partition to the c disk ? I would not like to reinstall everything.Thanks for your answer.

Hello, To move the Boot Configuration Database from 100MB partition to disk D, follow these steps:1. Click the Start button, then in the "Start Search" box, type CMD but DO NOT press Enter yet.2. In the list above, under "Programs" right-click on CMD that appears above and choose "Run as Administrator" and click "Continue". 3. In the open window, type the following command and press Enter:diskpart select disk 0 \\ I assume that the 100MB partition is in the first disk. list vol select volume 0 \\I assume that the 100MB partition is installed in " volume 0"inactive select volume 1 \\ I assume that the OS is in " volume 1"active Then exit the diskpart and Run CMD as administrator once again, type in:C:\windows\system32\bcdboot.exe C:\windows /s CIf it prompts that the command line is successfully. Restart the computer. Then you are able to boot the computer without the 100MB partition. You can also delete this 100MB partition.

I had trouble with the last line. C:\windows\system32\bcdboot.exe C:\windows /s C Did not work, however C:\windows\system32\bcdboot.exe C:\windows /s C: Worked fine.
