I found no answer online for a long time !!
Let's take a look !! Can I retrieve linux !! Or you can send a linux statement in the MENU. LST file in grub! Or you can load files in linux.
First, you need to know the name of your Linux boot file.
For example, initrd *. img and vmlinuz *
Can be written in menu. lst
Title operating system name
Kernel (linux partition)/boot/vmlinuz * root =/dev/linux partition // change vmlinuz to the name of your file, which is generally started with vmlinuz and linux partition, change to the partition installed in linux
Initrd (linux partition)/boot/initrd *. img // change initrd *. img to your file name, which should start with initrd.
Boot

If you really do not know the name of your linux boot file, then when you run grub.exe on a soft disk, press c to enter the command line mode, enter kernel (linux partition)/boot/vmlinuz, and press tab. The name should be automatically filled. If not, if you press twice, a list is displayed, and the version number is the highest.
Do not press enter to continue entering the root =/dev/linux partition and press Enter.
Then input initrd (linux partition)/boot/initrd press the tab method and press the Enter key.
Boot press ENTER
So all input content should be

Kernel (linux partition)/boot/vmlinuz * root =/dev/linux partition
Initrd (linux partition)/boot/initrd *. img
Boot
Yes.


Press esc to enter the GRUB editing status.

If grub can be executed, you can solve the problem. Install windeft and press c to enter the command mode and enter:
Root (hd0, *) // change * to the partition location of your linux instance. Drive C is 0, drive D is 4, and so on.
Enter
Kernel/boot/vmlinuz * root =/dev/hda * // * replace all with you
Actual Situation
Enter
Initrd/boot/initrd *. img // * replace
Enter
Boot press Enter.

Ps. we do not recommend that you use Hongqi 4.1. I have used it in the company, but it has poor performance and many changes. We recommend that you use debian or gentoo, a version that is less commercialized, ubuntu is recommended for beginners.

Press the "e" key during startup. You may go to gruab.

If I want to use redhat, which version should I use? Also, isn't linux free? Why is redhat linux sold on the market?
Red Hat 9.0 is used most now. The so-called "free" means that if you download the system online for free, the software related to LINUX is also free, and the software you create is used by others for free, you can modify, use, and spread other people's software, that is, you cannot make money.
Selling in the market is a commercial activity, and they want to make profits using LINUX.
