A block list is used for specifying a file that doesn't appear in the filesystem, like a chainloader.ĭuring the installation of a Windows operating system a bootsector is written to the first sector of the partition on which it is installed (more than one sector might be used if the partition type is NTFS). The "+" symbol is used to specify a blocklist - in this case +1 is the first sector of the device (hd0). Where (hd0) is the whole of the first disk, (hd1) would be used to boot the MBR of the second hard disk, etc. The following menu.lst entry for example.
After entering the last command you will also need to run the boot command (this is not needed in configuration file entries). To run from the command line omit the title command entry. NOTE - all of the following examples are configuration file entries, however they can easily be amended to run from the command line interface. Load Windows NT/2K/XP Recovery Console (cmdcons).For chainloading devices refer to the following sections -ĭirectly chainloading OS files has an advantage over chainloading the device, as a partition or floppy (or partition/floppy image) with a corrupted boot sector can still be booted (as long as the filesystem remains correct). By chainloading the device Grub4dos can be used to boot unsupported partition types, as long as the operating system uses the MBR and/or partition boot sector as part of the bootstrap process. Both methods involve using the chainloader command, one to boot the device, the other to boot the operating system kernel or bootloader file(s).
Grub4dos utilises two different methods for booting operating systems - both of which can be used via command line or configuration file entries. Grub4dos Guide - Boot Options Grub4dos Guide - Boot Options
