It's been 13 years but if anyone wonders... I had the same issue with a specific motherboard... confused me profoundly... turns out some few bios providers have an option in the SATA controller settings that says "AHCI mode: Automatic". Meaning, it switches between modes when it detects Windows XP vs. Windows 7. That switch causes restart during OS loading (and that includes the installation CD/DVD being inserted). Set it to "Manual" or "Enabled"... issue solved. That's also required if you want to install XP with slipstreamed drivers (else it will automatically default to IDE mode, always).

Encountering a mysterious crash while dual booting Windows 7 and XP can be perplexing. The simultaneous operation of these two operating systems requires careful configuration to avoid conflicts. Common culprits include incompatible hardware, outdated system files, or bootloader issues. To troubleshoot, check hardware compatibility, update system files, and review boot configurations. Use diagnostic tools like CHKDSK and examine Event Viewer logs for insights. Considering virtualization as an alternative can also provide stability. By addressing these factors systematically, you can unravel the mystery behind dual boot crashes and ensure a seamless experience on both Windows 7 and XP.

If anyone is curious, it has been 13 years since I experienced the same problem with a certain motherboard, which really perplexed me. However, it turns out that a small number of bios suppliers offer an option labeled "AHCI mode: Automatic" in the SATA controller settings. That is, it alternates between modes based on whether it recognizes Windows 7 or Windows XP. When the operating system loads—including when an installation CD or DVD is inserted—that switch forces the system to restart. Adjust it to "Manual" or "Enabled" to resolve the issue. In order to install Windows XP with slipstreamed drivers, you must also do that; otherwise, IDE mode will always be the default.
