Desktop computers, smartphones and other products of the core is actually operating system, platform competition is always the main melody of digital products. Whether it's windows or iOS, there are countless products that have tried to compete with Microsoft and Apple before they succeed, but they have certainly contributed to today's pattern, to see the 11 forgotten operating

ROOT is the command for GRUB to identify the hard disk and file format, telling GRUB what the Startup Device is and how to MOUNT the file format of the Startup Device. In the next step, you can find the GRUB configuration file and start the core, or start the imgfile.

While it's not surprising that Satrana della, the company's CEO Satya Nadella, announced Microsoft's liking for Linux at the Windows 10 Preview conference, this is still a bold statement for Microsoft, a company that sees Linux as a threat to its core business.At the same time, Microsoft also announced the free provision of visual Studio Community 2013.

of memory. Fifth, the popularity of software varies. Currently, 64-bit commonly used software is much less than 32-bit commonly used software. The principle is simple: there are fewer users using 64-bit operating systems. Therefore, software developers must consider the "input-output ratio" and invest limited funds in software for more users. This is also an important reason for the relatively high price o

That is, grub is used to select multiple kernels. Use software such as bootloader to replace the boot program in MBR or the boot program in PBR, such as ntboot loader in windows and Lilo and grub in Linux.
