I use two removable drives in my PC. One has Windows 7 Professional installed and the second has Windows 7 Home Premium installed. Both of these contain fully licensed copies of Windows 7. The Windows
7 Professional hard drive started as a Windows 7 Home Premium drive before it was upgraded to Professional. I use each drive for various purposes.
For most of the last year I could place either drive in the computer's removable drive slot and use either one without any problem. Then, beginning, I believe, after a Windows 7 update about 4 months ago, each time I replace
one drive with the other in the drive slot, Windows 7 will not start. Instead I received the following error message: The heading at the top of the error window reads, "Windows Boot Manager". Then the following message is displayed, "Windows failed
to start. A recent hardware or software change might be the cause." It then requires me to insert the original Windows 7 installation disk and select "Repair Computer" for it to "fix" the Boot Manager. The "repaired" drive works normally
then, no matter how many times I restart my computer. However, when I replace the "repaired" drive with the other drive, the problem starts all over again until I "repair" the replacement drive.
Additional information on the screen is as follows:
On a separate line the following is displayed, "Status: 0Xc000000e"
Then on the bottom of the display, the following is written, "Info: The boot selection failed because a required device is inaccessible."
How do I stop this from happening? Each time i change hard drives, I have to "repair the computer" using the Windows installation disk. This is a pain in the ass and I'm concerned that there is some function counting the number
of times I'm repairing the operating system and after a while it will tell me I cannot do it any longer. There seems to be nothing about this on the Windows website.
