I have installed XP after the installation of Windows 7. Now I can not boot Windows 7.
LifeH20, you'll need to use EasyBCD even if you like it or not.
First use EasyBCD to reinstall the BCD bootloader (manage Bootloader->reinstall Vista bootloader->Write MBR) (which brings back win7 but 'vanishes' XP) then reboot into win7. In EasyBCD in win7 ADD a entry for XP (go to Add/Remove Entries, select Windows NT/2k/XP/2k3 in the dropdown box, select the drive letter for the drive that XP is on, then press Add entry.
Yes you are right, i tried it after steves Suggestion even when i was afraid of it. And wohaaa it solved my problem.
Check out these articles on how to set up dual boot. Maybe you missed a step somewhere.
I am currently working in Windows XP, Windows 7 is also installed already in i: drive.
Previously there was a dual boot menu because i installed Windows 7 after XP, but then XP got some problems and i simply formated c drive and reinstalled XP.
Now there is no menu to dual boot.
I have once tried the Easy BCD and i am afraid of this tool, by using this somehow i became able to load windows 7 but Windows XP boot vanished. I did all that shitty stuff again (reinstalled xp and then windows 7).
