unknow hard error c00000135

Blue screen with the message “STOP C0000135 unknown Hard Error”. 
Anti-virus deleted some essential files in windows system and caused this problem. Normally, the loss of advapi32.dll, Gdi32.dll, Kernel32.dll, or/and User32.dll will show this message. Try to copy the files from other computer to fix it.

Another case is the file c:\windows\system32\csrsrv.dll was detected by some antivirus but it is false positive. Please restore the file from virus vault or from other computer.

The problem is caused by the HP1020 or HP1080 Printer Driver. I had not find a solution for that until now!

IBM / Lenovo Rescue Recovery Factory Restore Media

If you encounter this message. you can try this below:

“You can have only one copy of the Microsoft Windows operating system. The Product Recovery Media Creator will exit now.”

Open FactoryRecovery folder and look for service_done.ini. Copy this file in a different place just to have a backup file. After that, open the original one FactoryRecovery\service_done.ini and change the string done=1 to done=0.

After that , you can make the recovery media once more. Good luck!

ddrescue

Command for ddrescue

using rescuecd
----------------------
ddrescue -b 4096 /dev/sda1 /mnt/windows

using ubuntu live cd
---------------------------
sudo -i
start update manage and enable univise
apt-get install gddrescue

ddrescue --no-split /dev/sda /dev/sdb --force

--force * sometimes will be needed to force it to write on the target drive. Use with care. It will erase all data on the target harddisk.

*** Remarks

/dev/sda is the source & bad drive
/dev/sdb is the new & empty drive

*** Some examples procedures

First you copy as much data as possible, without retrying or splitting sectors:

• ddrescue --no-split /dev/hda1 imagefile logfile 

Now let it retry previous errors 3 times, using uncached reads:

• ddrescue --direct --max-retries=3 /dev/hda1 imagefile logfile 

If that fails you can try again but retrimmed, so it tries to reread full sectors:

ddrescue --direct --retrim --max-retries=3 /dev/hda1 imagefile logfile
