Windows 7 cannot start "bootmgr is compressed" SOLUTION

Today, I am unable to start because I have a problem with this document. When I start the system, I read the following black and white words: "BOOTMGR is compressed Press Ctrl + Alt + Del to restart ". I asked her what operations she had done. She said she didn't know. I 'd like to forget it. I came back to search for the dog.
Back, I searched for it. It turns out that it was caused by disk compression on the system disk. I wonder who promoted this bad optimization technique? The most simple manifestation is that the system runs slowly after the system disk is compressed, and other faults after optimization are not mentioned. Later, I confirmed to my colleagues that she made disk compression ...... O (Clerk □clerk) o
Now you know the reason, and you can solve the problem. There are several methods for your reference:
Fault description: The instance cannot be started after it is started. The error "BOOTMGR is compressed Press Ctrl + Alt + Del to restart" is displayed"
Cause of failure: Right-click drive C and select "compress this drive to save space". As a result, the hard disk partition table or Startup File is compressed incorrectly.
Fault Applicability: Windows Vista \ Windows 7
Solution
Recommended Methods:
Insert a Windows Vista \ Windows 7 installation disc and start it from the disc (you may need to modify the startup sequence settings in the BIOS)
Select a language, time, currency, keyboard, or another input method, and then click Next
Select "repair your computer"
Click you want to repair, select the operating system, and then click Next
In the "system fault recovery options" dialog box, click "command prompt"
Run the following command to restart bootrec.exe/fixmbr and Bootrec/fixboot.
Do not forget to uncompress the disk in the system. Otherwise, the system will compress the disk again after a period of time.
If the above method cannot be used for restoration, it is recommended that you try to use Win PE to enter the system and cancel the compression of the system disk.
Start the WINPE System, right-click "my computer", right-click drive C, and remove "compress this drive to save space". Click "OK". The system starts restoring drive C to compress, an error may occur during this process. Ignore the error and confirm the restoration.
Same as the second method, start the disc and open the "command prompt"
Enter the following commands in sequence:
Expand bootmgr temp
Attrib bootmgr-s-r-h
Del bootmgr
Ren temp bootmgr
Attrib bootmgr-a + s + r + h

Same as the second method, start the disc and open the "command prompt"
Go to the system32 directory (for example, c: \ Windows \ system32) of Windows Vista \ windows 7, and then "compact/u c: \ bootmgr"
Run compact/u/a/f/s: C: \ to decompress the entire partition of the system disk.
In fact, I got the first method .......
