I tried installing the windows 7 rc, which o downloaded from the windows homepage.
I want to install it on a virtual machine using the latest version of VirtualBox.
The host system is Windows XP sp3.
I mounted the iso file to the virtual machine and started it afterwards.
Then it said "windows is loading files" when it reaches 100 % the whole pc (including host system restarted).
I don't know why, or what i can do about it.

Hello Larth,

It seems like you are experiencing a problem while trying to install Windows 7 RC on a VirtualBox virtual machine running on a Windows XP SP3 host system. The issue you are facing, where the whole PC restarts when the Windows installation process reaches 100% in the "Windows is loading files" stage, can be due to several reasons. Here are a few troubleshooting steps you can follow:

1. Check VirtualBox Settings:
- Ensure that your VirtualBox settings are correctly configured, especially the system settings like memory allocation, CPU cores, and virtualization options.

2. Verify ISO Integrity:
- Check the integrity of the Windows 7 RC ISO file you downloaded. Corrupted ISO files can lead to installation issues. You can try redownloading the ISO or verifying its integrity using checksums.

3. Update VirtualBox:
- Ensure you are using the latest version of VirtualBox to avoid compatibility issues with newer operating systems like Windows 7.

4. Enable Virtualization in BIOS:
- If your host system supports virtualization technology (VT-x/AMD-V), make sure that it is enabled in the BIOS settings. This option is usually found under "Advanced CPU Configuration" in the BIOS.

5. Disable Antivirus and Firewall:
- Temporarily disable any antivirus or firewall software on your host system. Sometimes, security software can interfere with virtualization processes.

6. Try Different Installation Settings:
- During the Windows 7 RC installation in VirtualBox, you can try tweaking some settings like chipset type, graphics controller, or enabling/disabling hardware virtualization.

7. Monitor System Resources:
- Keep an eye on the system resources of the host machine while the virtual machine is running to ensure that there are no resource constraints causing the restart.

8. Check Event Viewer:
- After the restart, check the Event Viewer on your host system for any error messages or detailed information about the cause of the restart.

By following these steps, you should be able to identify the issue causing the restart during the Windows 7 RC installation on VirtualBox. If the issue persists, feel free to provide more details or logs for further assistance. Good luck with your installation!
