Run the following command on the grub command line

Grub > rootnoverity (hd0,0)

Grub > chainloader + 1

Grub > boot (hd0,0)

Command interpretation

Root

Usage: root [DEVICE [HDBIAS]]

Description:

Set the root partition. Set the root partition to the specified device (DEVICE), and then try to attach the partition to get the partition size (for passing in ES:ESI, as required for sector-chained startup). The BSD driver type is used to start the core boot of BSD), and to determine the PC partition where the BSD subpartition is located. Optional disk offset parameter for the BSD core to determine how many controllers are in front of the current controller. For example, if there is both an IDE and BSD disk, and the SCSI root partition is on the SCSI disk, then the disk offset is 1.

Rootnoverify

Usage: rootnoverify [DEVICE [HDBIAS]]

Description:

Similar to the `root' directive, but do not test to install the partition. This is used when some systems are installed outside the disk area that GRUB can access, but still need to set the correct root partition. Some parameters that require the installation of a partition to determine may be problematic.

Chainloader

Usage: chainloader [--force] FILE

Description:

Load sector chain loader. If the-- force parameter is used, the validity of the boot flag for the sector is ignored.

Boot

Usage: boot

Description:

Boot a loaded operating system or sector chain loader.
