Windows 7: lost dual boot with vista after windows 7 install

lost dual boot with vista after windows 7 install


I just installed windows 7 ultimate on my pc.
i already had xp32 and vista 64 business on a dual boot on the same HDD before installing windows 7.
during windows 7 install, I selected the xp32 partition, formatted it and installed windows 7 over the top as I no longer wanted xp32.

When the windows 7 install was complete I expected to see a dual boot screen with
option 1. windows 7
and option 2. vista64

unfortunatelty i have no dual boot options, the pc now just goes straight into windows 7. It doesnt sem to know that vista is there.

i would appreciate assistance in getting a dual boot set up with vista64 and windows 7

Vista & Windows 7 RC

Hi Phil,
I've same problem as you but had vista 64 already installed,
then installed windows 7.

But for some reason I don't get dual boot option to boot into windows 7.
System loads straight into Vista as usually.

Would EASYBCD sort this issue out, and how easy is it to use?

Vista + Windows 7

another way is to go to msconfig in Run, but this will only let you choose the default OS to load

Install EasyBCD 2.0 beta after doing quick registration to use beta, add the missing OS in Add/Remove by name, type and correct drive letter.

If the missing OS shows up in EasyBCD but won't boot, remove it and Add again.

If this fails to set up your dual boot correctly, please post back a Screenshot of your full Disk Management drive map and listings, as well as EasyBCD listings. Use Snipping Tool in Start Menu, attach file using Paper Clip in Reply Box.
