I have a 2TB hard disk with a 100MB boot partition and a large C: partition containing Win7. I added a 1TB SSD, and used EaseUS to copy the boot partition to it, and then copy and shrink the C: partition to the rest, which it did successfully during the reboot process.
I configured the BIOS to boot from the SSD, but it's still running the OS off the hard disk. Disk Management shows the hard disk with a 100MB "Active, Primary Partition", and a "Boot, Primary Partition" as drive C:. It shows the SSD with a 100MB "System, Active, Primary Partition", and a "Primary Partition" with a higher drive letter. So it appears the BIOS is indeed loading the boot manager from the SSD, but the BCD is still forcing it to load the OS from the hard disk.
Booting with the hard disk unplugged fails, and asks me to run System Recovery from the install disk, but I don't have a DVD drive.
I want to swap the new and old OS partitions, so that it loads the OS from the SSD as drive C:, and maps the old copy of the OS on the hard disk to a higher drive letter. It seems like "bcdedit" is the correct tool to use, but the information it displays isn't even remotely self-explanatory, and the help messages aren't either. I don't even see how to refer to the partition I want to boot from.
I don't want to add an entry to the boot menu, I just want to change the sole entry to refer to the new disk. That can't be hard. What commands do I use, and how do I tell it what partition to use? By a GUID, I would assume, but I don't even see how to find out the GUIDs of the partitions.
