New: HDHacker Portable 1.4 (MBR and boot sector manager) Released

Am I missing something? How do I restore the MBR using this utility if I can't boot into Windows? (Hi John. Did try to post under Support, but no entry as yet for this app)

My freeware Avast! AV warned that this "app" was rated dangerous/suspicious and asked if I wanted to download and run it "sandboxed"...although I also have the freeware app "Sandboxie" installed in my now ancient Sony VAIO P4 1.8 GHZ 1 GB RAM desktop computer with Win XP Pro installed on one of the 4 PATA HDD partitions. I can't afford a new desktop or laptop computer, (that include newer and better SATA, HD-DVD, internal IDE slots for graphics cards instead of just ONE AGP slot, and USB 3.0 and Firewire 400/800 connections) and is primarily due to my now being disabled and relying on a small fixed income, so I am always looking online for free Windows-related tools, apps, and software programs that I can install instead of directly into my Windows OS and/or into a separate NTFS/FAT32 formatted and created partition, and then they most often ALSO insist or require that they are included starting up immediately upon boot, as well as accessing and installing themselves into the Windows registry, but MUCH preferably those that can be configured or are already pre-configured (Portable Apps .paf for example :-)) to install instead into a thumbdrive, CD, DVD or external HDD to save on/ or reduce the use of physical RAM, virtual and pagefile memory, and best of all, they run ONLY when I WANT to run them.

Despite being able to run this app sandboxed at first, and checking it out, I instead decided to remove and delete the download and did not install it, b/c of installing either or both LILO and Grub bootloaders corrupting a MBR or maybe a user with or using admin/root privileges, somehow messing up a Windows MBR can often be repaired, that is, IF one knows how and what to use to do it. All you need is a downloaded version of the live Knoppix OS (calls itself the "Swiss Army Knife" of Linux-based distros) then burn the ISO file to a CD or DVD and use the OS to repair the MBR that included a Windows OS boot file record that likely was corrupted by installing a different Linux or Unix-based distro after a Windows OS was installed beforehand. It happened to me recently when I installed a variant version of the Free BSD (Unix-based) OS into the same HDD but into a pre-formatted and completely separate partition, which for some reason, corrupted a previously installed Linux OS LILO, that did detect and include a boot option into my WinXP Pro OS.

After running a live Knoppix DVD, (that operates and loads itself solely and only into RAM, (although the OS can be installed as Debian Linux into a HDD partition) and then completely disappears w/o a trace after shutdown) I was able to repair the LILO boot-loader and once again boot into Windows.
