Why does Premium Security NOT scan/offer to fix corrupt boot sector.

In the “old” days, viruses attacked the boot sector (of floppies then, but HDDs later on), The latest Premium Security AvastPE version Rescue Disk does a marvelous job scanning and pronouncing every file (that is FILE SYSTEM file) as clean. No mention of the actual boot sector, or even the Master Boot Record (MBR, I understand the distinction), which, like British Royalty, have no names. Can someone please explain this to me, and maybe point me to a version (or even another product) that does this? I’ve been down due to an (NTFS) INACCESSIBLE_BOOT_DEVICE stop code for four days and had hoped AvastPE would address this.

Thanks very much,

Ironically, I will have to boot with the Avast Rescue Disk in order to even read any replies. This while I’m l searching for something to repair my corrupt BOOT SECTOR…
