Windows 7 boot manager on wrong drive

Disk 1 is assigned the c: drive and is partitioned to the full space of the disk in a single primary partition.

Once up in the OS, the old drive is the d: drive. Both disks are basic. This was discovered in process of installing a larger drive with the intent of cloning the c: to that. Since it has been working fine, I wasn't aware that the boot manager was installed on the "wrong" disk.

I haven't had to touch this since XP and had no idea it wasn't a simple boot. I'd like to resolve this non-destructively, keeping in mind that my goal is to have a 3rd disk in the system if that helps with any scenario. I could then clone to the 3rd drive keeping the boot manager intact. So any tool , Information on how I can fix this would nice. This thread is locked.

I have the same question 7. Report abuse. This is usually an issue those with multiple drives encounter. This generally happens because the computer may not know which drive has the bootloader by default. There are plenty of third-party tools out there that can do the same job as the first method, only with fewer steps.

One such tool is MiniTool Partition Wizard. By following any of the two steps, you should be able to change the boot drive of your PC without any issues. Perform a system restore.

Restart your computer and boot from the Windows installation disk. Click Repair your computer. Choose the target operating system. Click Next in the System Restore wizard. Select the proper restore point and click Next.

Confirm your selection and click Finish.
