Sorry for top posting.
Let me give you a clearer idea.
1. My regular boot freezes after loading is completed.
2. I read on the internet that sometimes due to an update in VirtualBox,
this error might occur. To rectify it, I must re-install VirtualBox's Guest
Additions. For this, I require booting in a Single User Mode.
3. For that, I followed the correct steps as given here (
https://www.centos.org/docs/5/html/Installation_Guide-en-US/s1-rescuemode-booting-single.html).
But still the system froze on that same point.
4. Then I read about an Emergency mode which is even lower level to that of
Single User mode. I was able to log in and see the files that I
created/modified as root. I could not see any file/folder that related the
local user "cloudera" on which I used to work. This is where I thought of
seeing the contents of the Image using vmxray.com and found that a large
part of the dick is not visible. This part contains that files related to
"cloudera". I felt as if any information related to "cloudera" user has
been lost.
I basically need to access files that I made as "cloudera" on CENTOS and if
possible re-install the Guest Additions that ma solve this issue. But for
this I need to be able to boot as a Single User.
