I apologize in advance for the length of this post.
I have two computers. I recently set up a dual boot system with XP Home and Vista Business on Computer 1. Everything worked smoothly. (Both are 32-bit OSs)
Yesterday I attempted to set up a dual boot system on Computer 2 using XP Pro and Windows 7. In this case the XP Pro is 32-bit and the Win 7 is 64-bit. (The computer manufacturer's tech support said there should be no problem with this.)
Step 1. Create a second primary partition (using MiniTools Partition Wizard). The HDD is 300GB. I allocated 100GB to XP and 200GB to the second partition where I planned to install Win 7.
The partitioning appeared to go smoothly, but when I tried to install Win 7 the installation failed and I got an error message that said:
Windows could not start because the following file is missing or corrupt:
Please re-install a copy of the above file.
This computer was given to me along with a “reinstallation disk,” which I discovered does not have a Repair option. In the end, I was forced to reinstall Windows XP. However, when that was finished I was left with a weird situation. When I turn on the computer it acts like a dual boot system and goes to the “select OS screen.” Only the two selections are both Windows XP. When I boot from the first XP, things work normally. If I try to boot from the second XP, I get the error message telling me I have a missing or corrupt file.
At that point, there were two partitions – one had Windows XP installed on it; the other, larger partition, was empty. I used PartitionWizard to eliminate the second partition and return the first partition to 300GB. That went smoothly.
However, the dual boot screen still exists.
Does anyone have an idea of what went wrong? Is there a way to fix it or will I have to reformat the hard drive and begin all over?
Intel Quad Core Q6600 2.4ghz
Currently 2GB of DDR2 RAM installed (2GB waiting to be installed)
Windows XP Pro 32-bit
Windows 7 Pro 64-bit
The computer was manufactured before Windows 7 came out, so the onboard graphics and sound have to be moved to installed cards with Windows 7 drivers. Otherwise, the Windows 7 upgrade adviser and the computer manufacturer both said the computer should be able to run Windows 7 (both 32-bit and 64-bit).
(Note: I have DualBootPro, but I’ve no idea how to use it. I tried reading the “Help” file and it didn’t. I tried opening it to have a look and I received a warning that I hadn’t backed up my BCD Registry. When I tried to do that it told me;
-DualBootPRO was unable to save the backup to the -specified location. Some problems may include -insufficient disk space (NO), unauthorized access (No?), and/or a corrupt file (Is this the infamous “hal.dll?”)
DBP then asks if I want to open the error reporting screen, but when I click OK/Yes nothing happens.
My computer knowledge is simply inadequate. Any help or suggestions would be greatly appreciated.
