Thanks!
Hm, it seems you are now getting unsure about your first answer: "core.img is *the* part of grub 
which is installed in MBR gap"

Hopefully some developers are reading this thread. Maybe they could implement a new option, 
reporting GRUB 2's size in the MBR gap.

core.img is the part that is installed in MBR gap, but it does not mean
that it was this particular file. grub-install creates core.img
in /boot/grub and embeds it in the same run, but it is also possible to
directly use

grub-mkimage -o /tmp/foo.img ...
grub-bios-setup -c /tmp/foo.img ...

You wanted to be absolutely safe and sure. The only way to be is to
reinstall grub using grub-install.

Did you try any of script I mentioned? If they did not work we need to
fix them.

You mean, after I would have shrinked th MBR gap?
That's the problem!
What will happen, if the gap is too small?
For that reason I *before* wanted to know how much space is needed.

I'm thinking of a command like "grub-info", which should output such information.

I tried:
your bootinfoscript
--> bootinfoscript.txt
your findgrub
--> findgrub.txt
Ubuntu's boot_info_script from Ubuntu Software Center
--> RESULTS.txt

As you can see in the attachment, none of these provided the size of the used bytes in MBR gap :-(

All modern partitioners set the first partition to sector 2048, and for 512 byte sectors that's 1MB. Since the MBR consumes LBA 0, which is 512 bytes, core.img can be as large as 1048064 bytes.

If the gap is too small, then core.img can't be embedded in the space. Installation fails.

Never use the exact number for this. It changes e.g. between versions
and setting exact size would block any upgrade. It will also disable
Reed-Solomon. Just left 1M-1 sector. This is guaranteed to be enough and
results in nocely aligned first partition.

Ah thanks. I now understand what you wanted to say.
My focus  was only the question on how to determine the size of the used bytes in the MBR gap, not 
if they are exactly the same of /boot/grub/core.img.

Well, after installing Windows 7 + Ubuntu on a new big (500 GB) harddisk, I was "disgusted" about 
the waste of 2048 sectors ahead the 1st partition, which I respect, that could be seen as nitpicking 
;-) This lead me to the assumption, that GRUB could use more than 62 sectors of the MBR gap if 
available, to avoid some kind of 2-step loading. Theoretically there could be a possibility to use 
GRUB without any dependency on an existing Linux installation/partition on the disk.
My initial goal was to manually shrink the MBR gap to the "usual" 63 sectors to avoid this "waste".
A 2nd goal: reducing the size of my MBR+GRUB backup. As you know, installing whatever Microsoft OS 
will destroy that data. So why saving 1 MiB (=2048 sectors) if ~26 kB are sufficient?
3rd: To my knowledge, some old OS, e.g. MS-DOS, require the old CHS alignment of sectors on the 
disk, where the maximum for a cylinder is 63 sectors. I suspect, if it is possible to install MS-DOS 
on a 2048-sector-aligned disk.
4th: the remaining space could be used for some other sophisticated purposes. This is not of my 
current interest, but theoretically may be for other people.

1.) see above.
2.) I had installed Ubuntu on a USB-pendrive. There the MBR gap was only 32 sectors (=16184 Bytes). 
So I came to the assumption, that the hidden-sectors part of GRUB must be smaller than that, and the 
core.img file in the file system must be 2nd part of the GRUB bootstrap. And behind that, I wanted 
to check out, if I could additionally install Windows by help of Bart PE on the same pendrive, using 
GRUB as boot manager.

1MiB is nothing on the disk sized several hundreds gigabytes and it's
surely not worth the pain and the speed penalty.

Aligning on MiB boundary increases speed as well. And do you really care
about 1 MiB on 500GB disk?

Wrong. Windows rewrites only MBR. Also the only officially supported way
to install GRUB is grub-install

Only very old DOS may need something like that. Anything after ~1995
will work fine with unaligned partitions. And running anything made
before ~1998 natively on modern hardware is asking for trouble on many
levels. If you're interested in running such software, use VM, they're
very performant and save you loads of trouble when running dinosaurs

This space is to be used only by bootloader. Anything else should use
files.Files is how data is organised on modern computers. You need a
very good reason to use anything else.

Because if you need this info, then you're doing something very wrong.

RE: How many sectors for GRUB 2

[Elliott, Robert (Server Storage)]

Starting a partition on LBA 63 (historically common for MBR) or LBA 34 (historically common for GPT)  is a real bad idea for:
- HDDs implementing large physical sectors (e.g., 4 KiB)
- SSDs (page sizes are 4 KiB, 8 KiB, or larger)
- Logical drives presented by a RAID controller (strip sizes in powers of two ranging up to 256 KiB or even 1 MiB are common)

1 MiB is a simple choice that works well on all those types of storage.  You can retrieve more precise alignment tips from the SCSI Block Limits VPD page, but tuning the image for one drive could leave it non-optimal if image copied to another drive.

1 MiB may not be optimal for a RAID logical drive's stripe (with an "e") size, but that's a secondary concern to aligning to the strip size.
