Black screen, blinking cursor, 'asking for cache data failed';after Ubuntu update
New to linux, ubuntu, and this forum.
I have enjoyed ubuntu for the past few months, but after my last update installation ubuntu would boot to a black screen and blinking cursor. If I let it sit for a while it would give the following:
12.3456789 sd 6:0:0:0 [sdb] assuming drive cache: write through
.............................asking for cache data failed
It would then repeat the lines above but the numbers would get higher.
It would never boot.
I tried a live backtrack and knoppix usbs, and when trying to access my ubuntu files I get:
THIS DIRECTORY HAS BEEN UNMOUNTED TO PROTECT YOUR DATA.
From the graphical desktop, click on:
"Access Your Private Data"
From the command line, run:
Running the above in a terminal gave me this:ERROR: Encrypted private directory is not setup properly
I would ideally want to solve this problem and boot back into ubuntu, but if not, I really want to get my files off the hard drive so I can save them before I wipe and reinstall(yes, I should have backed up:()
I have tried to edit the grub with nomodeset and rmmod the ums_realtek, and a few other things I have found with google. None have worked so far.
Any suggestions on how to get my files back or even fix this?
Thanks a million from a newbie.
