Stop at grub

Boot stops at grub-general Linux technology-Linux technology and application information. The following is a detailed description. This article briefly introduces the solution that dual-system cannot be started and stops at grub!

Grub usage:
Grub is a multi-boot management tool that can be used to start many operating systems. It is a boot program independent of the running operating system. Unlike Lilo, which relies on linux for configuration and maintenance, Lilo also provides command line mode similar to Bash, allows you to set Grub more conveniently.

The dual-system cannot be started: it cannot be accessed when it is stopped at grub>.
The reason is that the grub. cong file is damaged.
Solution:
1. windows Recovery:
Grub> rootnoverify (hd0, 0)
Grub> chainloader 1
Grub> boot
Note: run the rootnoverify command to make grub not mounted (hd0, 0) Partitions. You only need to know that the system on this partition will be started soon;
Chainloader 1 means to specify the first sector on the partition to start the system;
Boot with the boot command.

2. Start linux:
Grub> root (hd0, 7)
Grub> kernel/boot/vmlinuz root =/dev/hda8 ro
Grub> boot
Note: the hard disk partition location of the following parameters will be mounted after the root command;
After mounting is complete, the kernel command loads the system kernel with its parameters,
(The linux kernel is usually named vmlinuz under the/boot directory );
The last two parameters are transmitted to the loaded kernel.
Root =/dev/hda8 indicates that the root directory of the kernel is located in/dev/hda8, and the mounting is required to be read-only (ro );
Finally, run the boot command to start the installed linux system.
