MBR Master Boot Record. I think so because one of my oracle professor told me that master boot record is the source to the windows booting setup. not confirm i think so.
To fix the Master Boot Record on a Windows 2000/xp computer you must: 1. Boot to the install media 2. When prompted, choose Repair. ultimately, you'll access the Repair Console 3. If necessary, log into your Windows application 4. There is a utility on the install media called FIXMBR.exe, On the command prompt, type FIXMBR and press enter. When Windows is installed, it creates the Master Boot Record on the first sector of the first hard drive. It makes a second copy or backup of the Master Boot Record immediately after the original on the hard drive. FIXMBR copies this backup copy of the MBR to the MBR location. If you still cannot boot, repeat steps 1-3 above: 4. There is a utility on the install media called FIXBOOT.exe. on the command prompt, type FIXBOOT and press enter. When FIXMBR fails to restore the Master Boot Record, FIXBOOT will read the information of the install and rebuild the master boot record from scratch and install it on the first sector of the hard drive. It will also create the backup.
What is done immediately after the bootstrap finds the operating system boot record? The BIOS reads the boot record into memory, and then passes control to it. The boot record looks on the hard disk for the kernel, or a loader program (depending upon the design of the operating system). If it can't find it, it prints an error message and then hangs, otherwise the kernel or loader is read into memory, and control is passed to it. The operating system then begins its initialisation process.
You could boot it, but it would never get beyond the initial stages. The setup program looks for the CD after it starts so it can read the rest of the files. Since it does not know how to read a USB Flash drive, it will not find the files it is looking for and will fail.
The master boot record (MBR) on a floppy diskette is located in track 0, sector 0. This sector is at the very beginning of the disk, specifically at the top side when the diskette is inserted into a drive with the label facing up. The MBR contains the boot loader and partition table, crucial for booting the operating system. In DOS and MS-Windows environments, this sector is read first during the boot process to initiate system loading.
Yes. There are several options for this:MacDrive - a commercial program that can read and write HFS+ volumes.Paragon HFS+ for Windows - similar to the above,Apple provides free read-only drivers via Boot Camp.HFSExplorer - A free read-only program
/boot directory is where all the file to boot Linux are stored it include the kernel image , initial ram disk. This files are read by the boot loader at the boot time.
The boot program is typically stored in a specific area of the Read-Only Memory (ROM) known as the BIOS (Basic Input/Output System) or firmware. It is placed in ROM because this memory type is non-volatile, meaning it retains its content even when the power is turned off. Storing the boot program in ROM ensures that the system can always access it to initialize hardware and load the operating system when powered on, providing a reliable start-up sequence.
The GRUB bootloader gets it's menu off of the Ubuntu partition. Since you deleted the Ubuntu partition, it can't read the list or know what to do next. You have two options:1. Reinstall Ubuntu.2. Boot from the Window XP CD, access the Recovery Console, and runfdisk /mbrThis will rewrite the Master Boot Record, and shouldallow you to boot back into Windows.
A computer boots up by first running a program in Read Only Memory (ROM) that is built into the computer's motherboard. This program is called the Power-On Self Test (POST) and Basic Input/Output System (BIOS). After checking the hardware, the program consults a nonvolatile parameter memory (called "PRAM" or "CMOS" for historical reasons) that acts like Flash memory in that it can be changed but retains its information without power. From this parameter memory, the program in ROM decides where to look for the next step.Typically the next step is to read the first block ("boot block") off of the first hard drive into memory and run the program in it. Other options are to read the first block off the floppy, the CD-ROM, or from the network.In the hard drive situation, the program in the boot block figures out which disk partition is the active partition, loads the boot block from that partition into memory, and runs that program. This allows you to have different operating systems on different partitions and choose which one to run by changing active partitions.The second boot block program loads a more elaborate loader program from the disk, which in turn loads the operating system (finally!).Most PCs have a "BIOS screen" that you can get to by a key sequence (F1 or ESC) during the boot process. This BIOS screen allows you to change the nonvolatile parameter memory; however, it is possible to make changes that will keep your computer from booting, so be careful. For example, bad values in "RAM Timings" will cause serious problems.
