照理来说不可能 看看你的光碟机是不是真的有在跑 就算出现问题 应该也是lilo出现错误 也就是你安装完成以后开不了机

It is not related to linux. Once you set the cdrom boot first, you should boot up the winxp cd at least. No matter what OS / bootloader in your harddisk.

1. Make sure your winxp cd / cdrom works and readable (no scratch)
2. cdrom is set to the first boot device
3. boot up your pc with the winxp cd in your cdrom drive
4. “Press any key to boot from cdrom …” - press enter when you see this sentence

Hope this can help.

重灌LINUX前你可以不重灌XP也可以重灌，这要看你个人的情况了
