I've had a test system running for over a month now. I wanted to install XP on a second drive. The XP installation got through everything i needed to before rebooting. Upon reboot, the Vista drive responds with "error loading operating system".
I tried to run the Startup Repair utility from the Vista DVD and it claims it can't fix the boot sector.
I'm about to go ahead and backup my stuff and just install XP first and Vista 2nd, which I know works, but this is really not a very good outcome. Installing XP on an entirely different drive should never corrupt the c-drive vista boot partition.
Installed Vista Beta 2 then XP, Vista now broken
XP always writes a new master boot record on install as will Windows 2000. In essence, you could view it now as XP is installed first and reinstall Vista and you'll have your first second scenario. A repair install may be an option given to you once in setup. "David Cornelson" <David Cornelson@discussions.microsoft.com> wrote in message

If you are attempting to dual boot then you need to partition your primary system drive into two partitions. Use one for the installation of an older operating system and you need to do this first. Then boot your VISTA CD and choose the option in the BIOS to boot from DVD/CD and then install vista into the extended partition. Then you can easily dual boot which is what I am doing now.

You can try this:
Windows Vista no longer starts after you install an earlier version of the Windows operating system in a dual-boot configuration

I get why all of this happens, understand how it would work, and have tried the repair in that support article. "bootsect.exe -nt60 all"
The repair did not work. I think this is the flaw. Maybe Vista needs to automatically backup the entire bootmgr info somewhere where XP couldn't damage it and then have a tool that can easily undo what XP does. Maybe that's what bootsect is supposed to do, but it's not working on my machine and it sounds like from reviewing other people's comments on this problem that it hasn't worked for them either.
If nothing else, I would expect MS to have a detailed tech spec on what has happened and how it can be undone by using disk tools.

Standard practice - always install the "older" OS first in a dual boot situation - repeat "older" first. Install Vista from within XP - select custom install and designate drive/partition for Vista - results in dual boot setup. Setting BIOS to boot from CD(DVD) drive and installing Vista may result in drive letter designations being reversed within Vista - no problem a as long as you are aware of the change when using Vista.

I think that's clear. Since discovering my problem, I have learned the way I was supposed to do this. But I'm in this little hell we call Vista broken by XP and I want to know if there is a way out _without_ reinstalling everything from scratch.
So my Vista drive is overwritten with XP bootldr stuff.
Is there a way to restore the Vista boot manager or not? 1) Tried bootsect -nt60 c: without success 2) ? 3) Reinstall XP first, then Vista.
That's my question.
It will take you longer to fix it (when you figure in the time spent waiting for replies to these posts) than to just do it all over again the right way.

Try this:
X:\boot\Bootsect /nt60 ALL
Where X is yor CD\DVD drive. That should put all back into the BCD store.
