Hello I'm trying to do the dual boot with your program but Ican't. First let me say I have a Dell laptop with Windows 7 Home Premium and a2nd hard drive from another laptop which is exactly a clone of this one and Idid that with Acronis true image just to backup this drive in case somethinggoes bad and it shows on My Computer as OS(E). I swap the hard drives inside the laptop to see if it works and It did fine no errorsor anything just like the other one, but when I add the HDD with this program itgive the blue screen telling me "A fatal error occurred 00000x0 and windowwill shutdown" I cannot run the repair Cd because I can't never boot from the OS(E) as is recognize on my laptop. Question on the Add New Entry, on top it changed the name toMicrosoft Windows 7 then I choose letter E and on the bottom it shows " Portable/ ExternalMedia" then Hard drive, Iso, Win Peetc. I guess I shouldchoose Disk Image but what type should I check? I did Raw Hard Disk Image is thatok? On the Edit Boot Menu it show OS(C) Windows 7 and second Os(E) MicrosoftWindows 7. Honestly I don't know how to do this so any help will be greatly appreciated.
