Yes, I have installed Windows 8 CP, after this installation the problem begun.
In the NeoSmart Blog under "EasyBCD is ready for Windows 8 CP" at March, 6, 2012 "Shukree" gave me the advice "Just edit by EasyBCD any entry in BCD file and you will be reverted to old text-based boot menu".
This have I done.
Now I have again the old text-based boot menu, but when I choose the "Earlier Windows Versions" entry in the boot menu I get the message "Invalid boot.ini-file. booting from C:\Windows." This message is not true, the arc-pathes of my Windows XP partitions are correct. In the moment, only the first Windows XP partition is reachable.
Can EasyBCD here help?
