Win7 system startup item problem solving

First of all, how do I install win7, I did not use the CD to install, because I did not have the tools to engrave the CD. 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 PE, run virtual drive from the booted system, and then install win7; 2) After the installation is completed, delete the 7777 directory of C drive, this The directory is the directory of pe; delete it directly; the problems encountered are: 1) Every time I boot, there is still a startup item PE, I found a lot of methods on the Internet, one of which is to use bcdedit to manage win7 Startup item, you can use bcdedit to delete the extra startup items; I used it to successfully delete the windowxp startup item; however, there is no content about pe in bcdedit; there is no way to delete this; 2) I think: bcdedit can't find it inside The startup item about pe 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: So that win7 does not use boot.ini to boot the series, 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.
