Black Magic with WinXP Boot.ini and Windows 7 boot file

Why Black Magic? Let me get to it.
I had a dual boot Win XP and Windows 7. One beautiful day last week, my Windows XP hard drive seized and is now as good as dead.
The Windows 7 Hard drive works, but Windows 7 won't boot.

I have already tried just about everything I could, so if you think of something, I probably tried it.

The bottom line is that the only documented way to fix this issue would be to go back in time and either install BCDedit on my Win7 drive or perform a clean install of win 7. Which is what I did on another hard drive, by the way.

Now, since my options are limited but I have a perfectly good win7 installation that won't boot, I found this tutorial:

Migrate to Windows 7 from an XP dual-boot configuration | Microsoft Windows | TechRepublic.com

which explains how to "properly" eliminate the WinXP partition from a Win7, WinXP dual boot.

One of the steps, unfortunately, is to copy the Boot.ini and other files from the WinXP partition to the Win7 partition, which I cannot do. Otherwise, there is little difference between my situation and the one in the tutorial.

This is where the black magic comes in: what if I go to another WinXP computer (say, my netbook or an old winXP I have) and copy the Boot files from there, paste tehm into my win7 drive and edit them to reflect a dual boot, then proceed with the same steps as the tutorial?

What do you windows geniuses think? Can it work?

Do any of you have a dual boot winxp/win7 boot.ini code you could post for me to copy?

Thank you very much for your help.

Do a repair from the W7 disk. W7 is not finding the Master Boot Record.

I have tried that numerous times. The win7 installation disk first says there is something wrong, then it says it fixed it. I restart, and nothing. Then I do it again, again is fixed. Now it just says everything is fine, still it won;t boot.

By now I have tried the repair with the win 7 disk no less the 12 or 13 times. It just won;t work.

Not only that, but by exploring all my disks with my Mac (mounted as USB drives) I did a fresh install of Win 7 on another disk and that only has one Boot folder under windows/boot

yet, my original win7 disk has 2 boot folders: one top level under C and one under windows/boot.

Believe me: if there is a solution posted anywhere on any forum, I have tried it, I have been at this for 3 days now. This is a real problem, but if you guys can take a look at the tutorial I mention above
Migrate to Windows 7 from an XP dual-boot configuration | Microsoft Windows | TechRepublic.com

you'll see that it covers pretty much the same situation as mine with the difference that in the tutorial the elimination of WinXP is intentional while in my case it's due to a disk failure.

However, I really think copying files from another Win XP installation may work but I would appreciate a second opinion from someone that has not been staring at my computer for 3 days.

Thanks.

You need to make the Win 7 partition active. Use a third party partitioning software, or boot to the Install DVD or Repair CD and run Diskpart. If you would like the commands for diskpart, post back.

After the Win 7 partition is active, a repair install should work.

As Saltgrass says, if you cannot get Startup Repair to write the MBR to Win7 partition after repeated attempts with reboots, then it is because it is not correctly marked active, or Win7 is damaged, or HD is not set to boot first..

Unplug the dead XP HD, set Win7 HD first HD to boot (after DVD drive).

Boot into Win7 DVD, select Repair, click through to Recovery Tools list to open a Command Line, type:

DISKPART
LIST DISK
SELECT DISK # (replace # with Win7 HD)
LIST PARTITION
Select partition # (for Win7 partition)
ACTIVE
EXIT

Now return to Recovery Tools list to run Startup Repair up to 3 separate times with reboots until Win7 starts.

You can also do this using free Partition Wizard bootable CD, which will Modify>Mark Active and Rebuild MBR with a graphical interface.
