○ problem of bcd area
・ "Computer Management"-> "Disk Management"
It is necessary to check the "System reserved" area on the left side of the C drive.
As a confirmation method, assign it to the Z drive etc. and check free space from Explorer.
On the PC at hand, it says "capacity 99.9MB" "free space 30.7MB".
Although it seems that there is a small amount of free space, it is impossible to expand the free space,
Discard this partition and follow the steps to create another partition
・ Make space on the disk containing C drive
Right-click on drive C and select "Reduce Volume"
Make a vacancy because it should be about 1GB.
Allocate the free space you created to Z drive etc.
Execute the following from the command line
Bcdboot.exe c: \ windows / s z:
Diskpart
Select volume z
Active
Now, from the viewpoint of "disk management"
The characters "mark partition as active" in the original "system reserved" area can be selected
When you right-click on the Z drive, the characters "mark partition as active" can not be selected because it is outlined
It has become.
If you look at the Z drive in Explorer,
of "$ RECYCLE. BIN", "Boot", "System Volume Information" and "bootmgr"
You can confirm that there are files and folders.
It is safe to delete the Z drive assignment.
Confirm that it can be restarted as final confirmation.
※ "bcdboot.exe c: \ windows / s c:" in bcdboot.exe and it may be together with the system drive todo
※ It is not a disk part but from "Manage Disk" to "Mark partition as active" It may be todo
○ Backup
"Control Panel"-> "Backup and Restore"-> left pane "Create System Image"
Select the backup destination USB disk etc from "On hard disk" and "Next"
As a point of doing this correspondence, before work
"System reserved" area was checked for backup,
It is not in the state now.
Instead, the area worked as Z drive is checked as "(system)" and is not removed.
Make sure that "(System)" and "(C :) (System)" are checked and can not be removed
Click "Next".
At that time, if the original "(System)" is checked and three checks are entered and it does not go away
There is a possibility that the work of bcd is not done well.
If you understand the theory, you just have to do it,
You want something to be a bit more convenient.
It's also a bit scary to change the bcd area.
