I had a computer with windows XP in an older Hard Drive and Windows 7 Home Premium 32bit on a newer one. Windows 7 was installed after windows XP.
On startup, I got the dual boot screen, and I could choose between both.
I didn't want the old windows XP, so I formatted that old Drive (using minitool partition wizard). Result: no boot now from windows 7... I read on Microsoft website that I shouldn't have done that, since the PC uses the startup files from the older operative system to start the computer on a dual boot.
Now, what can I do to make my Windows 7 installation work? The Hard Drive has everything untouched, of course, and all my files are there. I can always install it again and move my files, but that's a lot of work.
Is there any solution?
