After a long time, I finally made up my mind to change my laptop system from Win8 to ubuntu13.04 ..
But after the installation, there was a small problem... Several partitions in the original system cannot be entered ..
The error is similar to the following
PS: Forgot. The general meaning is as follows: Error mounting/dev/sda6 at/Media/CJ/new volume: command-line 'mount-T "NTFS"-o "uhelper = udisks2, nodev, nosuid, uid = 1000, gid = 1000, dmask = 0077, fmask = 0177 ""/dev/sda6 ""/Media/CJ/Add volume "'exited with non-zero exit status 14: The disk contains an unclean File System (0, 0 ). metadata kept in Windows cache, refused to mount. failed to mount '/dev/sda6': operation not permittedthe NTFS partition is in an unsafe state. please resume and shutdownwindows fully (No hibernation or fast restarting), or mount the volumeread-only with the 'ro' mount option.
I found the cause on the internet, saying that it is a problem with Win8's default fast shutdown, resulting in "metadata kept in Windows cache, refused to mount.", so that "the NTFS partition" is in "unsafe state ".
You need to go back to the original Windows system and shut down the system completely... (For quick shutdown problem reference: http://www.itt168.com/kuruantuijian/8009.html)
However, my original Win8 system is already in the format .. Overwrite the installation... I will never reload Win8 again...
After thinking about it, I made a win7pe. after entering the system, I opened all the partitions, shut down them normally, and then went into the newly installed ubuntu!
(I don't know if winxp pe can be used. I didn't test it)
