Virtual Machine systems cannot guide-general Linux technology-Linux technology and application information. The following is a detailed description. I got a virtual machine, which also led to the learning of the surrounding students. Haha, I installed a virtual machine and a linux system for them. As a result, the system cannot be guided after powe is off frequently, this is mainly because the grub boot program is not found, so 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
> Root (hd0, 0)
> Setup (hd0)
> Kerner/vmlinux _ you can press the TAP button to display a prompt (so you have to write down your system information)
> Initrd/initrd TAp (loading file system)
> Reboot
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.
