Linux cannot be booted in virtual machines

Article Title: Linux cannot be booted in virtual machines. Linux is a technology channel of the IT lab in China. Some basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open source, have created a virtual machine, which also drives the learning of peripheral students, after installing a linux system for them, the system often fails to boot after powe off. This is because the grub boot program is not found, then we will fix the descent. Here we still use redhat9 as the column.

First, enter the virtual machine, press F2 at the beginning of the boot screen, enter the bios configuration, select the disc, use our installation disk, and insert the first one, press F5 at run time to enter the prompt linux-rescue press enter (Press enter all the way down), enter single-user mode, # enter the command, enter cd/mnt/systembin here and mount the file like/boot, and then enter the sbin file # Run cd sbin. /grub-install/dev/hda)

Run grub./grub and enter it in the grub command line.

Restart to see if it can be loaded.

In this way, at least you can find the grub program and solve the problem later. You have to study hard.
