This problem has been plagued recently. I installed Ubuntu 10.04 in win7 and formatted the Ubuntu partition. However, a hard-to-delete system startup Item is left in the system, which is troublesome. Every time you start it, you have to wait. If you want to reinstall it and use wubi to uninstall it, it will not work. It is useless to find something on Baidu for a long time. How did Baidu do it. It took me so much time to find a solution. I really don't know how stupid their crawlers are. They always like spam websites.
Now let's share this solution with you!
A. Right-click "Start> attachment> command prompt" and Right-click and select "Run as administrator" to open the command line program as administrator;
B .enter "Export bcdedit.exe" in the "command prompt" and press Enter. You can view the specific content of the two (or more) menu items, and find the code similar to {items} in the resumeobject line in the obsolete system.
C. Enter bcdedit/delete {code} to delete the obsolete menu.
This method also has a simpler operation method: Enter cmd in the run box, then bcdedit/delete {ntldr}/F, and press Enter.
