MkCDrec
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
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 the pure installation of Ubuntu is complete, no boot device (nobootabledevicefound) is output at the end of the screen instead of entering the GRUB interface. Apparently, the UEFI boot settings are screwed up. No boot device is available after Ubuntu is installed. I will tell you how to fix it on Acer.
Usually, I will install and start both

Update-binary is a binary file, which is equivalent to a script interpreter and can recognize the operations described in updater-script. After compiling the Android source code, this file is generated by out/target/product/tcc8800/system bin/updater. You can rename updater to update-binary.The name of the file in the update package is determined by the value of the macro ASSUMED_UPDAT

The first step to establish a bootable CD recovery is to download mkCDrec. When I write this article, the 0.6.7 version of the software has been published and can be downloaded. The pen downloads the mkcdrec_v0.6.7.tar.gz package and stores it in the/home/slowe

Just download the latest version of Lubuntu from the official website, make a USB or Live CD, and use it to start the system.Lubuntu 16.04 is supplied with PCMan File Manager (PCMANFM). As soon as you open the File Manager, all the partitions are listed in the sidebar. Now open the partition and copy your important data to any external hard drive or USB drive. That's it!Download URL

In general, the "boot sector that actually starts executing" is fixed to the 07c00, and the idea is to say a real boot sector.For a hard disk, there will be a primary boot sector, which then controls and other boot sectors, such as grub control Windows,linux, and so on.The primary boot sector is then loaded at 0600h, and the real bootable sector is loaded into the 07c00h when other

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
