Steps to get a Linux distribution installation system: First, the power-on self-test post is naturally Self-test completed according to the BIOS set boot sequence in turn to find a bootable (bootable) device, this is set to CDROM Load the MBR of the disc and then load the menu according to ISOLINNUX.CFG load Isolinux.bin to provide an option to install the operating system, select the appro

, and the extended segmentation cannot be formatted.--In a Linux system, the IDE hard disk has a maximum of 59 logical partitions (5-63), and the SATA HDD has 11 logical partitions (5-15)--extended split up to only one (OS limit)(3) main start record area (MBR) and boot processThe boot program, in addition to the MBR, can also be installed in each partition slot in the boot sector (boot sector), so that the multi-boot mechanism. The execution process for the Boot manager (multiboot) is as follow

For any system, booting is not just a matter of switching on the power, many things will happen in just a few seconds or a few 10 seconds, knowing that the complete process will be the precondition to solve any boot problem or increase the boot speed. Next, let's look at the Linux boot process in detail:1. Load the BIOS hardware information and self-test, and according to obtain the first bootable device;2. Read and execute the boot Loader (such as gr

UltraISO Soft disc is a powerful and convenient and practical CD-ROM image file production/editing/conversion tool, it can directly edit the ISO file and extract files and directories from the ISO, or from CD-ROM to make a CD image or the hard disk to make the file into an ISO file. At the same time, you can also process the ISO file startup information to create a bootable CD. With UltraISO, you can create/edit/convert disc image files as you wish, w

tables, so the executable code in the MBR is less than 512 bytes, and this code is not much. Note that each disk (or even floppy) contains executable code in its MBR, even if the code is only sufficient to output a message, such as "non-bootable disk in drive A: (There is no bootable diskette in drive A:)". This code, which is loaded by the BIOS from the first sector, is called the first stage boot loader

Mac EFI (which is often said on the PC BIOS) does not have a graphical interface management, generally through the startup of the combination key or hotkey to implement the modification function. In general, there is no need to modify it because it is the optimal setting. You can use the following startup key combinations on intel-based MAC computers Hold down the C key at startup-Boot from a bootable CD or DVD disc, such as a randomly shipped MAC O

First Category: Enable shortcut keys Press the key or key combination until the desired feature appears (for example, hold Option down during startup until the startup manager is started, or hold down shift until a "safe boot" appears). Tip: If the startup feature does not work and you are using a Third-party keyboard, connect the Apple keyboard and try again. Keys or key combination functions; Option Displays all bootable volumes (startup manager)
