Background
While REG ‘s Samsung 990 pro 2tb Keeps Crashing It have no choice to disable the Bitlocker and move the entire partition to backup. But when REG trying to reenable Bitlocker it comes with an error:
The System Cannot Find The File Specified.
Reasoning
What could cause this problem
- The corrupted system files
- The missing MSR partition
- The TPM
- The Unreadable ReAgent.xml file
Solutions
System files scan
First REG tried sys file scan chk
sfc /scannow
Since the sfc found error and fixed it, the problem remains
Create MSR partition
REG noticed that he didn’t create the MSR partition since he moved the system
so REG did this
On windows command prompt
Enter Diskpart cmd:
diskpart
List disk cmd:
list disk
Select your disk avec :
<!> replace “x” with your case
select disk x
before the next step make sure u have enough unallocated space like this
then create the msr with:
create partition msr size=128
the whole process looks like this in REG’s case:
C:\Windows\system32>diskpart Microsoft DiskPart version 10.0.xxx Copyright (C) Microsoft Corporation. On computer: DESKTOP-VOJR2AE DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 1863 GB 254 GB * Disk 1 Online xxx GB xxx GB * Disk 2 Online xxx GB 0 B * Disk 3 Online xxx GB xxxx MB * DISKPART> select disk 0 Disk 0 is now the selected disk. DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 System xxx MB xxx KB Partition 2 Reserved xx MB xxx MB Partition 3 System xxx MB xxx MB Partition 4 Primary xxx GB xxx MB Partition 5 Recovery xxx MB xxx GB Partition 6 Primary xxx GB xxx GB Partition 7 Reserved xxx MB xxx GB Partition 8 System xxx MB xxx GB Partition 9 Primary xxx GB xxx GB Partition 10 Primary xxx MB xxx GB DISKPART> DISKPART> create partition msr size=128 DiskPart succeeded in creating the specified partition. DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 System xxx MB xxxx KB Partition 2 Reserved xx MB xxx MB Partition 3 System xxx MB xxx MB Partition 4 Primary xxx GB xxx MB Partition 5 Recovery xxx MB xxx GB Partition 6 Primary xxx GB xxx GB Partition 7 Reserved xxx MB xxx GB * Partition 10 Reserved 128 MB xxxx GB Partition 8 System xxx MB xxxx GB Partition 9 Primary xxx GB xxxx GB DISKPART> exit Leaving DiskPart... C:\Windows\system32>
we have just crete partition 10 a 128m msr partition
but REG still got the problem remains.
Chk the TPM
tpm.msc
seems Nothing wrong.
The key to this problem: The ReAgent.xml file
Things seems no way out Untill REG find this blog:
Solution for BitLocker Error: โThe system cannot find the file specifiedโ
so REG renamed
C:\Windows\System32\Recovery\ReAgent.xml
to
C:\Windows\System32\Recovery\ReAgent.xml.old
and restart the computer
Then it works!
And windows recreated this file:
How does this even work?
What is ReAgent.xml ?
ReAgent.xml is a system configuration file used by Windows Recovery Environment (WinRE). It contains information about:
- The location of the recovery image
- Recovery environment settings
- BitLocker recovery support details
Why this happens to REG’s case ?
As mentioned earlier REG has moved his system partition to a backup and restored it .
While BitLocker tries to reference ReAgent.xml and itโs misconfigured. Causing the problem.
Further tips
enable bitlocker via cmd
this helps to identify the problem
manage-bde -on c: -rp
In REG’s case, theoretically it will get the error code 0x80070002 which help find out the problem quickly
