Fix GRUB boot

When I came back on May 1, I found that my colleague's computer could not be normally guided by grub and automatically entered the command line status of gurb. It is estimated that someone has moved, but fortunately, my colleagues have not been on duty, so they have time to fix it.

Run the kernel and initrd commands to boot the system into Linux and find that the system can be accessed normally. This indicates that it is only a boot problem. Then open grub. conf under/boot/grub.

I can't see anything. Apart from hiding menulist, I commented out the sentence and restarted it. the problem persists.

Later, it was inferred that the grub boot was broken and had to be fixed, so the grub command line was started.Root (hd0, 7)Here different machines will be different), and thenSetup (hd0)Restart ~
