Vista Home Prem 32 bit and Win 7 Pro 64 bit boot error

Postby dfwtx » Wed Apr 11, 2012 2:12 am

I have a two boot system with two distinctly different drives - one for Vista Home Prem 32 bit and a second one for Win 7 Pro 64-bit system. The Win 7 was JUST upgraded by Windows Anytime Upgrade from Vista Home Prem 64 bit to Win 7 Home Prem 64 bit; followed by a further upgrade to Win 7 Pro 64 bit.

I purchased DualBoot Pro attempting to install a boot menu for both OS's. Instead, it ALLOWS my Vista 32 bit to boot (default and initial pre-installed drive;) a second item, identified as the Vista 32 bit recovery boot (although I've not tried this one;) but no possible boot to the Win 7 Pro 64-bit system...no matter what I have tried...even after reading the helps and FAQs. It appears it cannot find the drive with the Win 7 bootloader (if that's what it's called) and there is only ONE partition for the Win 7 HD.

I am able to boot to either harddrive on "intial" computer startup or restart (in my case, using the F-12 key) when I "select" one drive or the other from a list. However, if I use the created menu with DualBoot, the Win 7 selection goes to an erroneous error; apparently not able to find the Win 7 drive (under Vista 32, the Win 7 drive is recognized as "I-drive." Of course, when I am in Win 7, it's recognized as the "C-drive.")

I read all about dual boots when you "first" install Win 7 from scratch but this isn't my case...it's an upgrade...thoughts, suggestions or ideas? Thanks...

You can try repairing the boot manager by booting from the Win7 DVD & choosing startup repair.

Thank you...I did try that but there was no affect.

Again, it seems that the Vista 32 bit side cannot find a Win 7 "bootloader." I am not certain that's what it's called. By default, it'll boot to the Vista 32 HD but no matter what I've done, the Win 7 Pro 64 HD is not recognized for booting from the created menu item...more thoughts or suggestions?

If I can't get it to work, I suspect I'll have to request a refund (if that's possible?)

Sometimes what I suggested has to be run twice to work.

Try this then W/ DBP go to:
Make sure all the drives are plugged in.
System bootloader tab
Check the windows Vista or Windows7 button
& All Drives
Install Bootloader
Restart the PC

Thanks...

I did try your suggestion AND from both drives this time -- that is, both from the Vista 32 AND the Win 7 Pro 64 OS/HDs. The Win 7 side did indeed install a bootloader (and menu) and then I further installed a second boot for the Vista 32...all works THERE on this second drive (the Win 7-64 OS.)

However, the Vista 32 drive (which is the original HD and installed OS) still does not allow me to boot to Win 7 on the second installed drive. Here's what I get: Error code 0xc0000428 - "Windows cannot verify the digital signature for this file." This is what I have seen throughout on the Vista 32 HD, whenever I attempt to boot to Windows 7 Professional. It further states that I can temporarily disable this function but that sounds just a bit dangerous in the long run.

But, indeed, the DualBootPro created a new boot menu for my second HD with the Win 7 Pro 64 OS, as the default, but I can only get to this HD and OS by using my system's boot manager (F12.)

Further thoughts, ideas or suggestions? Thanks for all your help thus far...
