我想把win7换成xp,结果出现了上面这个

大致翻译：
系统发现了一个问题,windows已经将系统关闭以避免对你的电脑造成损坏.如果这是第一次看到这个错误警告,重启你的电脑,如果再次出现,照以下步骤做：查杀电脑病毒,移除任何新安装的硬盘或者硬盘控制器,检查你的硬盘以确定硬盘被正确的配置.运行CHKDSK /F来检查硬盘损坏然后重启电脑.
win7到xp是新版本到旧版本安装,比较麻烦
解决方法:
1:请确认最近有没什么硬盘改动,有没加新的硬盘,或者对硬盘做一些更改等,或者有没对电脑安装新的驱动,软件.
2:开机按F8,选择,最后一次正确配置,或者安全模式,如果能够进去系统,把你最近对电脑的更改还原,如删除最近安装的软件.
3:考虑是否硬件故障,如硬盘等.
