Windows 7: Problem starting pc with dual boot XP-Windows 7

Problem starting pc with dual boot XP-Windows 7

Hi everyone,
First of all please forgive me for my English as is not my native language.

Yesterday I installed Windows 7 on a hard drive which had XP previously. During the installation procedures everything went OK after I updated and installed some programs to test the new OS including a couple of games. After that I tested booting the previous OS, that is XP. Everything worked fine as well, even switching both Operating systems a couple of times during the rest of the day.

The problem began today when I turned on the PC for the first time and the black sceren with the option to select an OS wouldn´t respond until Windows 7 booted itself. But after a couple of minutes the PC was frozen, including mouse and keyboard, so I had to force restart the pc and it all worked fine ´till I turned the PC off.

After a couple of hours when I started the PC back on the exact same situation happened again. Pc no responding at first, just after restart.

One thing to add, which I don´t know if is relevant, is that I have 2 hard drives, one for the operating systems and another just for data.

Any kind of help will be very welcome. Thanks in advance!

It would be better to install the OS's to separate HD"s booted by the BIOS, unplugging the other HD when installing.

However for now mark the Win7 partition Active, then boot the Win7 DVD System Recovery Options or System Repair Disk to run Startup Repair - Run up to 3 Separate Times until Win7 starts and holds the System Active flags.

Then install EasyBCD (free Download at bottom of page - no name or email required) to Win7 to add XP on the Add OS Entry tab, by name, type, let drive letter autocomplete, accept boot files, reboot.

Thanks gregrocker. I will try that fix as soon as I have the time.

However I have one more question. Given that, as I mentioned before, both OSs seem to work well after restart, is it advisable to go on using the pc like that or will the problem get worse by doing so?

Since it's booting now please post back a screenshot of your maximized Disk Management drive map and listings:

1. Type Disk Management in Start Search box.
2. Open Disk Mgmt. window and maximize it.
3. Type Snipping Tool in Start Search box.
4. Open Snipping Tool, choose Rectangular Snip, click New, draw a box around full drive map and all listings.
5, Save Snip, attach using paper clip in Reply Box.

Tell us what is on each partition.

Hello gregrocker.

Here is the image. Problem starting pc with dual boot XP-Windows 7-hd-map.png

As yesterday, today on first boot the pc would not respond on the black screen where you choose the OS. Only the countdown went on untill windows 7 booted and worked fine, the pc did not freeze. When restarting from the (shoot down) menu both operating systems seem to work fine. So it seems the hang only occurs after first system boot and on boot manager screen.

I asked you to tell us what is on each partition.

From what I can see you have Win7 on C and likely have XP on D which holds the System boot files for both OS's.

Complicating things is the Disk1 is clearly a former factory OEM OS HD which still has the OEM partition which was not wiped or deleted before being used as a data drive (correct?). E is also marked Active as though the OS might even still be on there. Is it? I would immediately Mark Partition as Inactive which you can do from Win7 Elevated Command Prompt.

After that if the problem persists power down to open the case and pull the data cable plug from Disk1 to see if the problem goes away.

Sorry, forgot to tell you the content of each partition.
Partition marked as C has windows 7, partition D has XP and E has mostly files, music, movies, games, etc. and a previous OS that I used on another PC which, as you pointed out, was not removed as I though that wouldn´t matter. So perhaps that is the culprit.
So according to that, shall I proceed as you recommended or that leads to another method.

One thing to notice is that when I´m on XP the letters of the partitions change, that is, C for XP, D for files and previous OS and F for windows 7.

That's correct - since WIn7 was installed last it was able to also claim C when booted into it.

Yes, perform the steps I gave in my last post and report back. This will help determine additional steps if necessary.

Well, performed both steps, marked partition E as inactive Problem starting pc with dual boot XP-Windows 7-capture.png and unplugged the disk but the problem pesisted. When I boot the system for the first time the boot manager screen will not allow me to choose an OS untill Windows 7 boots and from then on everything works OK, even restarting from Shut Down menu and then black screen for boot choice works fine.
So as you can see the problem is not that bothersome but what worries me is that it may get worse, but if you consider otherwise I would continue using the PC like that.

The problem , in my opinion , is because 7 is installed on a logical partition. It should have been converted to a primary partition before the install was done.

Did you make that partition yourself ? Or was it already there ?
