generate boot tapes so that the tapes contain an image of the root volume group. This is also a storage method for a single disk system. When the disk fails, it provides a rapid recovery method. Of course, the mksysb image used for restoration should be newer. You can also use mksysb to install another machine, which requires some configuration, such as IP address, because almost everything on the original machine is copied to the tape. Back up the system image: # Smit mksysb The following page

Source: China Computer Education News For those who do not have a soft drive installed, most of them will choose a virtual soft drive, but unfortunately the capacity of the virtual soft drive is too small, so they have to be limited in terms of functionality. ISOEMU is an interesting software. After installation, you can use the ISO image file on the hard disk to guide the system, so that you do not need to use a dial when installing Linux. The principle is to use GRUP to boot the ISO file on th

in the active partition (bootable windows). The second windows may not be installed in the active partition, but its boot file must be in the active partition. The general order is: Grub --> windows?> Find the boot file-boot loading-start windows Grub --> linux-> Find the boot file (/boot)?> Boot-start linux If grub is installed on another partition, isn't it MBR? This is the primary partition where grub is installed. It must be set as an active part
