Boot issue with IBM Lenovo laptops

Description

After restoring a Reflect image your IBM Lenovo laptop will not boot.

Some older IBM/Lenovo notebooks use a system called 'IBM PreDesktop' to = handle system recovery. This essentially uses the BIOS to 'fake' the drive = geometry of the boot disk by reporting incorrect Cylinder/Head/Sector (CHS)= values. This leaves part of the disk 'invisible' to Windows and is where t= he recovery partition is hidden. The OEM MBR supplied with PC requires the = faked drive geometry values in the partition table in order to operate.

Solution

If you restore an image to the same disk attached to another PC or to an= external drive then the disk will have a different (correct) drive geometr= y reported and the restored image will fail to boot in the original PC. Thi= s is because the restore process correctly updates the MBR partition table = to correspond with the drive geometry on the restored disk.

To restore a IBM/Lenovo PC that uses PreDesktop you must have the boot d= isk attached to the primary disk controller of the same PC that created the= image.
