Method of installing Win7 under PE and Status: 0xc000000f solution

Everyone knows that all files in win7 have more than 2 G, and it is very troublesome to use DVD burning.
Here, I would like to tell you a good way to install WIN7 on a hard disk under PE without using CD-ROM:
First, make a bootable U disk with PE function inside; (If you computer If you have an optical drive, you can use the CD with PE to enter the PE.)
Second, extract the Windows 7 CD image file you downloaded to the D drive, such as D:\\Win7. Then right click on your computer's C drive to select the format, ready to copy the file;
Third, copy the bootmgr file and the boot folder in D:\\Win7 to the root directory of the C drive; and D:\\Win7\\sources directory Copy the boot.wim to the sources directory of the C drive (you need to create a sources directory yourself);
Fourth, start - travel - cmd into DOS, switch to C drive, run C:\\boot\\bootsect.exe /Nt60 c: The last line after the carriage return is successful, which means success.
At this point, take the U disk or CD-ROM drive out, restart the hard disk to start the installation state;
(If you can't execute it, you can execute it three times. The following is the code executed three times. After executing one line, press Enter to execute. Next line)
DOS code
c:
cd boot
bootsect.exe /nt60 c:
5. After rebooting, automatically enter the Windows 7 installation interface, select language and other preferences. Click Next to enter the installation Windows interface;
Six, do not point to "Install now", but point to the middle of the lower left corner "Repair the computer" ”! Then select the first item in the “System Recovery Options” <; use the reply tool that can help solve the Windows startup problem...”, then select the last one in the next “command prompt”;
Seven, after the pop-up DOS window, we switch to the D drive, and run D:\\Win7\\sources\\setup.exe to enter the normal installation.
(If you can't execute it, you can execute it four times. The following is the code for four executions. After executing one line, press Enter and execute the next line.)
DOS code

setup.exe
Eight, select the first partition in the partition state that comes out is C drive, then click the format below, then click Next to enter the normal installation state of Windows7. Then follow the prompts to complete the installation of Win7 very easily, and the whole process is basically over.
