bootable chkdsk

1. Linux startup Process AnalysisThe boot process for the Linnux system is as follows: Load BIOS hardware information and self-test, and obtain the first bootable device according to the setup; Read and execute the boot loader (i.e. grub, spfdisk, etc.) of the MBR in the first boot device; Loading kernel,kernel based on boot loader settings will start detecting hardware and loading drivers; After the hardware driver succeeds, kern

storage devices are in the computer, we take the hard drive as an example, the BIOS will be based on the user's settings to obtain a bootable hard disk (or USB flash drive, disk. The BIOS can set the boot order) and go to the hard drive to read the first sector mbr location . MBR This only 446 bytes hard disk capacity will be placed in the most basic , when the BIOS becomes full, And the next is the MBR in the boot management program work. Thi

block in the first sector of the first bootable device, which contains the boot loader. boot loader (boot loader): a software that can read kernel files to execute. Kernel file: Begins the functionality of the operating system. 4. Primary boot partition (MBR) 　　 Bootloader (boot loader) is a set of software installed on the MBR of the operating system, this program is small and perfect. The main tasks of this boot loader are the followin

BIOSThe basic input output system, which we refer to as the fundamental inputs and outputs, is generally stored in the BIOS chip on the motherboard.The first thing that runs when the computer starts is Bios,bios is responsible for checking the hardware and finding the

We open the soft disk pass (Uitraiso) software, and insert the CD into the optical drive.2, because is the installation system disk, so we have to make the CD boot file (not the correct boot file made out of the ISO is not bootable), we choose "Start", "Extract boot files from CD/DVD".3. Select the optical drive of your computer system (confirm

partitioned and formatted. We can boot the system through bootable discs, such as the win98/me boot CD, or floppy disks with bootable features. If your system does not yet support this startup mode, go to the BIOS setup program and modify the first boot Device to either the ATAPI CD-ROM Drive (CD drive boot) or floppy Devices (floppy boot). Use the Fdisk command to partition with CD or floppy boot system,

Windows XP has a much higher security performance than the previous Windows 9X, and we can protect our secrets by setting up a password for individual users, but what if we forget the login password one day? Is there no other way besides formatting the HDD reload system? Let's look for the secret to recovering Windows XP logins. 1. Create a bootable floppy disk to repair the user's password Microsoft in Windows XP provides us with the ability to cre
