Well done. This is the kind of technical information needed for some of the more advanced users. Good work. :)

Great Tutorial. :)

The thing that always makes me laugh a little is that DOS is still useful as a command line language. :)

Hi.

Let me start from the beginning.
I've downloaded W7 RC 7100 wrom MS site.
I burned it to DVD and tried to instal but I was getting error every time (0x80070002).
So I searched the web to solve the problem and found Your solution.
I followed it step by sep and everything was great.
But after using imagex when I was trying to use the command "bcdboot ..." I got error.
It was offcourse because I was using Win XP at that time.

So I found a sollution (at least I thought so).
I restarted my PC, poped in the W7 DVD I burned earlier and when the setup started I hit "Repair the system".

Everything was going ok, W7 was found and repaired. Than it started with no problem but as it occurred - my "previous C" partition was kind of disabled (screen from diskpart below).

So what do I do to enter my Win XP partition and not lose data from it (I have some files there that would be nice if I could recover them).

Please help...

Open diskpart and lis vol again, I'm assuming that vol 1 is the old XP. If it is just sel vol 1 and ass. That will assign a drive letter to vol 1.

Thanks for the answer. Currently I am at work so don’t have possibility to try it.

But I am curious about one more thing – will that partition be visible in boot loader?
Or will I have to use bootcfg command?

OK - I will see when I get home and try :)

I'm honestly not sure about that, Luciak. I'm guessing that it will not be visible in the bootloader but I'm sure we can add it if you'd like...

Wow - had some problems but finally I booted my old XP :)

Your advice was very good and worked but as You also predicted, XP partition was not visible in bootloader.

As I assigned the letter to my old XP partition I wanted to change it back to C:
And I did - but it cost me faliure in W7 boot and no boot for XP.
So I was a little bit crushed.
I was fighting with it for few hours but it was worth it :)
Finally I managed to add boot sequence for XP and I have learnt a lot bcdedit commands :)

But it's working :)

And my question is - can I somehow clean the bcd?
Because as I understand it it is still in the system, just not visible from XP.
Am I right?

EDIT:

Ok - I managed to clean it with easyBCD.

EDIT II:

I have a little comment to the quote below, according to my recent experience.

Quote:

The only hard requirement is that you be running Windows 7 or Vista.

You can do this operation also under Windows XP. The only difference will be tah You will not do whole operation in CMD.

When You will get to this point:

Quote:

D:\Mike\Desktop\work>imagex /apply e:\sources\install.wim 5 h:\

ImageX Tool for Windows
Copyright (C) Microsoft Corp. All rights reserved.

[ 100% ] Applying progress

Successfully applied image.

Total elapsed time: 7 min 8 sec

You will not be able to do this step:

Quote:

D:\Mike\Desktop\work>h:\windows\system32\bcdboot h:\windows

So what You have to do is to use EasyBCD to make Your new Windows 7 installation bootable.
Very helpful here is this thread:
How to Do a Dual Boot Installation with Windows 7 and XP
Start from point 7. of Method II and just adjust it to Windows 7 instead of XP.

Hope it will help someone to avoid the problems I had :)
And once again thanks for support.

You can do the bcdboot command if you change directory to where the DLLs that it depends on exist. I just found this out and hadn't yet added it to the tutorial. XP has some of the same DLLs as 7 but they're the wrong version for bcdboot. What you do is CD to the dir (h:\windows\system32 in the example) then run bcdboot with that as the current directory. That will cause bcdboot to pick up the right DLLs and it will work OK.
