Recently I had permissions problems with Windows Search, then I run Permissions Time Machine to restore the permissions to default (according this topic)
After this, I receive a blue screen on startup, with the 0xC000021A code.
In Advanced Startup Options, I receive an "access denied" for all files that I try access in command prompt!
However, I can access all these files by Ubuntu Live CD. There are a way to recover the permissions without reinstall Windows?
Try
sudo chmod -R -f 777 (your hard disk path)
on the Ubuntu Live CD (after mounting your hard disk)
(your hard disk path) would be, for example, /media/live/disk/*
rather then C:\
or /dev/sdb2
.
But BE WARNED: 777 applies read, write, and execute to the files. Some Windows files are not supposed to have these permissions (in Linux permission style, they would be closer to-rwxr-----
then -rwxrwxrwx
).
I have not tested this command but your system should boot afterwards.
