Win7 system startup item problem solving

win7 system startup item problem solving
First of all, how do I install win7, I did not use the CD installation, because I did not have a CD-ROM tool. I used pe to install Win7 under the recommendation of my classmates. The method is as follows:
1) Install pe under XP, then restart the computer, choose to boot from the PE, run the virtual CD-ROM from the booted system, and then install win7;
2) After the installation is complete, put the C drive 7777 directory is deleted, this directory is the directory of pe; delete it directly;
The problem encountered is:
1) Every time I boot, there is still a startup item PE, I found a lot on the Internet Method, one of the methods is to use bcdedit to manage the startup items of win7, you can use bcdedit to delete the extra startup items; I used it to successfully delete the startup items of windowxp; however, there is no content about pe in bcdedit; there is no way Deleted;
2) I think: bcdedit can not find the startup item about pe, it will be configured in other files. Decisively open the boot.ini and find that there are related settings for the PE, delete it. Restart the system, there is no PE startup item;
3) Summary: Although win7 does not use boot.ini to boot the series startup, but setting the startup item in boot.ini will also affect the startup of win7. Do not build everyone to use my way to install win7, Jianyi use CD to install, first delete the C disk data, so the installation of win7 is the cleanest, if you do not delete XP first, C disk will leave a lot of XP files.
