I recently installed windows 7 on a secondary hard drive. After I was finished I took the hard drive out, and tried to boot back into my main system (also win 7) on my ocz revo ssd.
(The 1st boot option was set to the ssd my main hd)
On boot I was confronted with a boot menu, I selected option 2 (my win 7)I then was lead to the windows recovery screen (like what you get when you stick in the installation disk)
I tried all the options to no avail. Interesting note: When prompted to select an operating system, the list was empty.
Sticking in the 2ndry hard drive I was able to boot into the windows installed on that drive, from there I found an interesting article stating the problem may be something to do with the primary drive not being set as active in disk admin.
I followed to instructions and rebooted.
phase 2: This time no dual boot options show. Just this screen:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
(telling me in 3 steps to repair via install disk)
After that it shows the following:
Info An error occured while attempting to read the boot configuration data.
So I stuck in the install win 7 disk and chose repair. (still no operating systems displayed in list) and I tried start up repair at least 5 times in a row. (I hear it only fixes one thing at a time.)
