10. Install GRUB. For example, to install GRUB in the master boot record (MBR) of the first disk, run
the following command:
setup (hd0)
11. Exit the GRUB shell:
quit
12. Unmount the mounted file systems and then reboot:
umount /mnt/system/dev/
umount /mnt/system/proc/
umount /mnt/system/boot/
umount /mnt/system/
reboot
13. Reconfigure the bootloader by using tools and documentation from the Linux distribution that
you use. For example, in Debian and Ubuntu, you may need to edit some commented lines in the
/boot/grub/menu.lst file and then run the update-grub script; otherwise, the changes might not
take effect.
6.3.11.2 About Windows loaders
Windows NT/2000/XP/2003
A part of the loader resides in the partition boot sector, the rest is in the files ntldr, boot.ini,
ntdetect.com, ntbootdd.sys. boot.ini is a text file that contains the loader configuration. Example:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional"
/noexecute=optin /fastdetect
Windows Vista/2008
A part of the loader resides in the partition boot sector, the rest is in the files bootmgr, boot\bcd. At
starting Windows, boot\bcd is mounted to the registry key HKLM \BCD00000000.
6.4 Validating vaults, archives and backups
Validation is an operation that checks the possibility of data recovery from a backup.
Validation of a file backup imitates recovery of all files from the backup to a dummy destination.
Validation of a disk or volume backup calculates a checksum for every data block saved in the
backup. Both procedures are resource-intensive.
Validation of an archive will validate all the archive's backups. A vault (or a location) validation will
validate all archives stored in this vault (location).
While successful validation means high probability of successful recovery, it does not check all factors
that influence the recovery process. If you back up the operating system, only a test recovery in
bootable environment to a spare hard drive can guarantee success of the recovery. At least ensure
that the backup can be successfully validated using the bootable media.
