One-click ThinkPad restoration in Linux

Fault description:

After the Linux system is installed on the Thinkpad T43 notebook, "Access IBM" may fail to boot the system to restore the partition, and the error "missing operating system" may be prompted ".

Solution:

If the restored partition is still stored on the hard disk, it can still be accessed. After Linux is installed, restore the partition to a hidden inactive partition, which is why it cannot be started. If the system is a dual-boot, Boot windows XP, click Start> run, and type c: \ ibmtools \ utils \ bmgr32/fbootmgr. bin/m2/ibm/r, and then click <OK> restart the computer to restore the system. When the system is started, click Access IBM to start restoring the partition.

If the pre-installed ibmtools folder is lost, you can copy the bmgr32.exe and bootmgr. bin files under the c: \ ibmtools \ utils.pdf paths from other T43 laptops to the local machine to perform repair operations according to the above parameters.

Bmgr32 is the Rescue and Recovery pilot Manager Control Program, which is located in the directory c: \ IBMTOOLS \ UTILS. Some parameters are described as follows:

Bmgr32 parameter description

/F mount the RRE Master Boot Record Program
The/M2 Rescue and Recovery environment is located in the DOS service partition and is only pre-installed in IBM)
/The IBM System is an IBM Computer
/R reboot the computer

Note:The above operations are personal experience. Explanations are taken from the IBM website documentation.

This method is not necessarily good for hard disks installed with LINUX. When I first had LINUX, it was hard to delete the boot program of LINUX in MBR, enter A:> FDISK space/mbr in DOS boot with boot disk with fdisk tool. The reason may be that IBM does not support LINUX.

Use the Fdisk command to fix

Fdisk is not only a partition program, it also has a very convenient function to restore the primary Boot Sector, and it only modifies the primary boot sector, other sectors are not written, therefore, it is undoubtedly an ideal Partition Table repair tool for those who are still using Windows 9x. When you use Fdisk to restore the primary boot area, first start the system with the Windows 98 boot disk and enter the "Fdisk/mbr" command at the prompt to overwrite the primary boot area records.

Tip: the "Fdisk/mbr" command only restores the primary Partition Table and does not re-build it. Therefore, it is only applicable to the destruction of the primary boot partition record by the boot partition virus or the loss of the primary Boot Record code, however, the primary partition table is not damaged. This command is not applicable to clearing all Boot viruses.

Use Fixmbr to repair boot records

In Windows 2000/XP, we generally use some enhanced commands integrated in the fault recovery console, for example, Fixmbr is used to repair and replace the Master Boot records of the specified drive, Fixboot is used to repair the boot sector that knows the drive, Diskpart can add or delete partitions in the hard disk, and Expand can be extracted from the specified CAB source file. retrieving lost files and Listsvc allows you to create a service list and display the current startup status of the service. Disable and Enable are used to Disable or allow a service or hardware device, respectively, enter the "help" command to view all the control commands and detailed explanations of the command.

For example, you can enter the "fixmbr" command to check the Master Boot Record of the current system on the console, and then "are you sure you want to write a new Master Boot Record ?" Enter "Y" later to confirm, so that the repair of the Master Boot Record is completed.
