Why is my OS after recovering from Acronis-image different from the OS before recovering (when it was the same)?
To clarify: I had a certain configuration with installed software and settings yesterday on 14th September that worked very fine. The laptop was quick, internet quick, startup decent. I immediately made an Acronis-image of this.
During a few hours after that configuration, I installed too much software and begun to get trouble with too slow startup and slow OS. So I decided to recover to this perfect Acronis-image to get back this perfect OS I had a few hours ago.
Took a while, but then I was greatly disappointed: I thought the OS would be exactly the same. Immediately upon bootup, I got a black screen for a long long time, and finally had to press the power-button to restart it. Even then extremely long bootup (without any external devices/hard drives attached), longest ever, until I finally got the Desktop displayed. Particularly the second part of bootup (after entering login credentials) took very long time.
I begun to get problems also here, after the whole system had started, with quite (not much) slow machine. After a while (maybe 10-15 minutes) however, the only difference to the perfect OS I had earlier was that the bootup is very slow (without any attached hard drives during bootup).
I wonder what the reason can be? Shouldn't the imaged OS be, and "behave", exactly the same as the perfect OS I had just before creating the image?
When I recovered, I remember I was given the option of selecting the partition with this perfect OS on (C:) PLUS another drive that was presented as something "subordinated" to C:
I'm not sure what this subordinated was, but didn't select it (only selected C:). Can this be the reason? Should I have selected this subordinated drive?
My OS is a Windows 7 Ultimate 64-bit. The imaging software I use is Acronis True Image Home 2012.
