| Hi Shane,
|
| The problem occured because the volume on the sata drive was designated
as
| the active one. By temporarily removing it, the system was forced to
install
| the bootloader elsewhere. All you really needed to do was change the
active
| partition before doing a startup repair.
|
| Keep in mind that only one volume can be designated as active, and it
| doesn't have to be the one that the OS is installed on. When the BIOS
passes
| control to the hard drive (boot device), it goes to the active volume -
this
| is regardless of where the operating system is installed. It is the
| bootloader here that tells the computer where the system files are
located -
| which volume on which hard drive - and then loads the appropriate file to
| start the OS (io.sys, ntldr, winload, etc.).
