Problem locating: 1. environment xp and ubuntu dual systems, ubuntu for wubi installation 2. to access the ubuntu system, you can only go to the grub prompt 3. after entering the ubuntu file system in xp, I found that the E: \ ubuntu \ disks directory disappears or cannot be opened (My ubuntu is installed on the E drive, so the E Drive mentioned below refers to the ubuntu installation drive letter) solution process: 1. start xp-run-enter the command "chkdsk/f E:". after the command is run, xp will fix the ubuntu file and move the file to the found.000 folder on the edisk (if the edisk does not exist, in disk C ). 2. open the tool-Folder option, and find the hidden E: \ found.000 folder by selecting "hide protected operating system files" and displaying all files and folders without selecting "hide protected operating system files, in disk c) 3. cut the files in the E: \ found.000 folder back to E: \ ubuntu \ disks \ and E: \ ubuntu \ disks \ boot. After restarting, you can re-enter the ubuntu system. Www.2cto.com 4. run sudo update-grub in ubuntu
