Requires Windows 7 and later. You shouldn't edit or modify this file, unless you are much familiar with GRUB2. A corrupted Grub boot loader makes a CentOS/RHEL system unable to boot and transfer the control further to Linux kernel. When you boot up your system and it stops at the grub> prompt, that is the full GRUB 2 command shell. But I have solved the problem and I could boot Live android-x86 on USB and installed android-x86 from Grub2 without changing to Legacy by putting following lines in /etc/grub. By the way, check in your /boot/grub/grub. You can start plpbt. Without kernel cmdline options, booting ISO images with GRUB2 will fail in the physical media check/test stage of the ISOs boot process. The Grml rescue system supports booting the Grml ISO from a hard disk. Creating a kicstart file from scratch on your own can be tricky so you have two options here. You can choose between Grub2 and Grub4Dos as the default boot loader. Dual boot systems which is having multiple OS running in a single desktop/laptop via logical partitions, often prone to GRUB issues. Like I already said we can configure boot loader settings from command line or GUI. You may need to turn the system off from the control panel and then back on to reach the GRUB boot prompt. For example, if you are completely paranoid and wish to have an option to erase your hard drive quickly, it is possible to set up something using DBAN.
