How to boot the Ubuntu file from the hard disk to DOS

Article Title: How to boot DOS from a hard disk in Ubuntu. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

We recommend a file system for Ubuntu, which is good for everyone. For example, let everyone know about the file system required for Ubuntu, and then give a full introduction to the file system required for Ubuntu, the purpose of writing this article is to release how to boot DOS from the hard disk without overwriting mbr.

Currently, DOS is used most often in Ghost. You only need to enable the hard disk to start with DOS. Therefore, vFloppy is not required (this is a frequently used one, however, we found that we could not use the compressed NTFS disk and threw it away.) First, we declare that all the files required for Ubuntu are from the Internet.

2. After downloading, release the boot directory and grldr to the system boot partition (usually a drive C );

3. edit boot. ini in the root directory of the system boot partition (deselect "Hide protected…" in the folder options required by Ubuntu... ", Select" display all files required for Ubuntu... ", And then cancel boot. ini read-only attribute), in the boot. add the last line in ini: c: \ grldr = "Start GRUB" is actually using the grub boot DOS image (here the system boot partition is a drive c ), "Start GRUB" can be changed at will, just as you can understand it.
