Recovery Scenarios

Fixing MBR after a boot virus attack

Let’s assume that the MBR (Master Boot Record) of your hard disk has been corrupted as a result of a boot virus attack,

thus your system fails to boot.

To fix the MBR of your hard disk, please do the following:

1. Start up the computer from our Linux/DOS recovery media.

Recovery Media Builder can help you prepare the Linux/DOS or WinPE recovery

environment either on a CD/DVD disc or a thumb drive.

To automatically boot from the recovery media please make sure the on-board BIOS is set

up to boot from CD/USB first.

2. In the boot menu select Normal Mode to use the Linux recovery environment (more preferable) or Safe Mode

to use the PTS DOS recovery environment (in case you’ve got problems with Linux). Moreover you’ve got the

option to boot into the Low-Graphics Safe Mode (PTS DOS safe mode) to cope with a serious hardware

incompatibility. In this case, only the minimal set of drivers will be included, like hard disk, monitor, and

keyboard drivers. This mode has simple graphics and a simple menu.

By default the Normal Mode will be automatically initiated after a 10 second idle period.

3. In the Linux launch menu select Boot Corrector. You can find it in PTS DOS as well.
