published March 8, 2018. The new virus has been attacked in various forms since it was discovered in early April. If this virus is infected, it will bind to the server and start launching the Salomon mining program called "Kkworker". 4. botnet is still active in the event of device restart Security researchers found the first IoT zombie virus that stops the system after a device restarts, and it remains on the device after attacking the system. This is a major change in the IoT zombie v

The MkCDrec (Read-Only CD for building a recoverable System) command is a tool for establishing a disaster recovery CD in Linux. It supports most file systems, RAID (cheap redundant disk arrays), and optional tools for System Fault repair. These tools include partition management tools, memory detection tools, and data recovery tools. In addition, mkCDrec supports most of the currently released Linux systems, including Red Hat 8.0 and Mandrake 9.
Start stage
after introducing the principle that UEFI starts Windows, take a look at the "UEFI-enabled PE" authoring method. The traditional PE previously provided by this blog is not bootable on uefi computers, why? As you can guess from the previous article: The EFI file is missing. And according to the previous article, 32-bit UEFI environment can only start 32-bit PE , 64-bit UEFI environment can only start 64-bit PE. The current computer is basically 64-bit

flag for this partition to on. For MS-DOS partition tables, only one partition on a hard disk is bootable. If you load LILO to a partition, the partition must be bootable (that is, you should set the boot tag of the partition with LILO installed to on ). For a PC98 partition table, all ext3 partitions must be set as bootable. (Parted will force this operation) '
disk partitions and to determine the active partition, which is responsible for handing over the boot to DOS or other operating systems on the active partition. This piece of program corruption will not boot from the hard drive, but can read and write to the hard drive from the soft zone or the light area.
The concept of extended partitioning is more complex, it is very easy to cause hard disk partition and logical disk confusion; the fourth byte of the partition table is the partition

Fixed the error where no boot device is available after Ubuntu is installed.
Usually, I will install and start both Ubuntu and Windows systems, but this time I decided to completely eliminate Windows pure installation of Ubuntu. After Pure Ubuntu installation is complete, no bootable device found is output on the screen instead of entering the GRUB interface. Apparently, the UEFI boot settings are screwed up.
No boot device is available after Ubuntu
The ext4 file system is always used for emmc storage devices. "Device" must be the path of the block device.
Emmc
An original eMMC block device is often used for bootable partitions, such as boot partitions and recovery partitions. Therefore, it is similar to mtd. EMMC has never been attached, but the mount point eMMc is used to searching for devices in the partition table.

Vfat is a FAT file system used in Block devices. This usually refers to
