Grub loading Stage 2..... while booting

by Joseph Moore In reply to Grub loading Stage 2..... ...

GNU GRUB (GRand Unified Bootloader) is a program that installs a boot loader to the MBR, which exists at the beginning sectors of a disk. It allows you to place specific instructions in the MBR that loads a GRUB menu or command environment, permitting you to start the operating system of your choice, pass special instructions to kernels when they boot, or discover system parameters (such as available RAM) before booting.

x86 Boot Process
When an x86 machine first starts up, the BIOS of thesystem checks for particular system parameters, such as the amount of RAM in the machine, the date and time, disk devices present, and the order in which those disk devices should be checked for bootable media. Usually, the BIOS is configured to check the machine's floppy disk drive or CD-ROM drive (or both) before attempting to boot from the hard drive. If no bootable media can be found in those removable devices, the BIOS usually turns to the first few sectors of the first hard drive for instructions on where to find and load an operating system. These first few sectors, commonly called the MBR, start the process of bringing up a pre-selected operating system, a GRUB menu of operating system options, or a GRUB command line interface to execute special options

Grub loading Stage 2..... while booting

The process of loading GRUB, and then the operating system, involves several stages:


Loading the primary boot loader, commonly called Stage 1.

The primary boot loader must exist in the very small space allocated for the MBR, which is less than 512 bytes. Therefore, the only thing the primary boot loader accomplishes is loading the secondary boot loader, due to the fact that there is not enough space in the MBR for anything else.

Loading the secondary boot loader, commonly called Stage 2.

The secondary boot loader actually brings up the advanced functionality that allows you to load a specific operating system. With GRUB, this is the code that allows you to display a menu or type commands.

Loading the operating system,such as the Linux kernel, on a specified partition.

Once GRUB has received the correct instructions for the operating system to start, either from its command line or configuration file, it finds the necessary boot file and hands off control of the machine to that operating system.


Note
Some filesystems, as well as filesystem configurations, may require a Stage 1.5 file that essentially bridges the gap between the primary and secondary boot loaders.

For example, if your Stage2 boot loader file is on a partition using a filesystem that the Stage 1 boot loader cannot access, it is possible to direct the Stage 1 boot loader to load additional instructions from the Stage 1.5 file that allows it to read the Stage 2 boot loader file. For more information, consult the GRUB info pages.

So, the whole point of that is that GRUB is a Linux boot loader thing. Did this system have Linux on it at one time? If so, sound like it is still there.

Here is the URL to this article on GRUB:

Thanks for the response and the LINUX / GRUB link. The operating system on the PC has been completely rebuilt, so cannot sniff for an LINUX connection at this time, but there is a strong possibility knowing who worked on the PC prior to the problemthat some pieces of LINUS may have crept into the Windows PC. Thanks again for taking the time to respond. I have copied your answer into me Key Word list.
