Lmao, well considering when you go out in outer space, and there's a new entity in front of you whom you know nothing about, are you gonna say hi to it first or start attacking at it.
I don't know, probably I would have already seen that entity coming thus having the time to post on the NASA board for advice.
The point is that I would be expecting that those actually familiar with outer space had some actual solutions to the problem at hand, not a generic "If the Apollo entity-recognition software didn't recognize that entity it is safer to nuke him/her/it and everything else in two-three light-years range around it ".
Now, seriously, a PBR can usually be re-built just fine, particularly in your case most probably the BPB (Bios Parameter Block) is just fine as you can access the files on that volume, so it is a matter of making sure of this and then use a simpler tool to write to it "standard" code, such as bootsect.exe can do with either the /NT52 or /NT60 switches.
At this point the PBR should normally be valid and BootIce would recognize it and allow you to further change it to some other code.
If you want you can dump your current PBR (and being a FAT32 some more sectors), upload it to any free hosting site and post a link to it and I'll have a look, only to make sure that the data is valid.
I would need the MBR (to check data in the partition table is coherent with the BPB data) and the PBR+15 sectors.
You can use the HDhacker to dump the data:
You want first sector of the Physicaldrive (save to mynicembr.bin) and first 16 sectors of the Logicaldrive (save to mybadbadpbr.bin).
Then make a zip or 7z archive, upload to *somewhere* and post a link.
Is it safe?
