can't boot to Windows 7 anymore (dual boot)

Apollo 13 · 02-01-09, 03:49 PM

So I had vista 32bit on C drive and had windows 7 32bit on F drive a separate drive. Well I formatted the C drive to put Vista 64bit on PC...now I can't even get to Win7 anymore. Can someone plz help me?

Sounds like you need to fix the boot sector but I'm not too sure on that, maybe another member here knows?

You could try Vistabootpro to fix the boot menu.
I've used it before with Xp/Vista and if Windows7 boot is same or similar to Vista's then it should work.

EDIT: If it's not working you have to reinstall windows7. The rule of thumb is install oldest OS first.

I believe you can boot from the Vista or Win7 CD/DVD and do the repair thing and it will fix it automatically. I know that's kind of vague, but I'm not sure of the steps. I did something like that in the past with Vista 64.

Boot from CD (win 7) select language and keyboard setup,

Click next, select repair your computer

it will look for win 7 installs

Then click on startup repair and it will scan for errors

and voila!! win 7 starup repaired, the images are from windows vista DVD but are the same settings on Win 7

I'm taking a wild guess.

Did you activate it?

when your computer boots, bios reads the first sector of the disk, which tells it what to do next.

for xp, it passes control to boot.ini, for vista/win7 it parses the "bcd store" (boot configuration database)

when installing multiple OS's, install your older ones first, then newer, then newest, to preserve backward compatability.

i havent worked out the details of repairing yet, but if you search for BCDedit you may find more useful details.

cheers!
