Testdisk is the one! It was on the bootmed Ubuntu disc that Yousuf pointed
me to (Thank you, man).
It's recovered all the partitions, and they are all as right as rain.
One problem; I get "missing boot manager" when I try to boot into the Win7
partition.

How do I create a MBR for it, bearing in mind that I'll be working from
either Win8 or some Linux live CD.

You can try a Startup Repair after booting with your Win7 install disk, if
you have one.

I had dual-boot on my computer until recently. Win7 and the Win8
development preview.
I guessed you missed the part that read in GIANT letters that it *will*
destroy the contents of the drive.

All I can suggest is a partition recovery tool, or even a file recovery
tool like Recuva. You messed up man.

Bootrec or bootsect would be available in the system repair environment.
That can be accessed by booting a Windows installer CD...

http://techpp.com/2009/11/11/download-windows-7-iso-official-direct-download-links/

or by using a 200MB repair CD.

On my Acer laptop, I received two prompts early on. One was a prompt
by Acer, telling me to get busy and make a 3 DVD plus 1 CD set of
discs, used to return the laptop to factory state.

But in addition, I also received a prompt from Microsoft while the
laptop was running, to burn a repair CD. The repair CD should then
match the installed version of OS (32 bit repair for 32 bit OS, 64
bit repair for 64 bit OS). That CD is roughly a couple hundred megabytes
and doesn't even occupy a full CD. It gives you a command prompt option
for example, where the bootrec and bootsect would be available.

You're also prompted to make a repair CD, after running an
image backup.

Now, what's interesting, is I can't find bootrec or bootsect on the
Windows 7 filesystem itself. The implication, as near as I can tell,
is the set of utilities is built into the repair CD. I was hoping I
could steal one, and run it from another Windows OS. But that
doesn't look like it's going to work out.

I was able to put the 32 bit repair CD for Windows 7 in my CD drive,
open the .wim file with 7ZIP and find both bootsect and bootrec.
Bootrec doesn't appear to be that happy about running on WinXP
(and I'd better be careful not to make it too happy :)). Bootsect
on the other hand (which I think fixes the MBR), appears to be standalone
and also ready to run in WinXP. I haven't tested it, but at least
it would give detailed help when I ran it.

So right now, I see the options as:

1) See if you burned the 32 bit or 64 bit repair CD already. Your
OEM computer should have prompted you within the first day or two
of usage, to do so.

2) Look for a torrent of the Win 7 32 bit repair CD. Using an archive
of the neosmart page, you can get a link.

http://web.archive.org/web/20091101....net/blog/2009/windows-7-system-repair-discs/

(The downloaded file contains torrent information. You need a torrent
tool to complete the ~200MB download. First one is 32 bit. Second one
is 64 bit. (Note - the md5sum of these does not match the md5sum of legit
repair discs. Caveat emptor. This could be related to the build version
for example, rather than being suspicious. Use the MD5sum values below
in a web search, for details.)

http://web.archive.org/web/20091106...cellania/Windows 7 64-bit Repair Disc.torrent

Looking in my archive, this is what I've got from that era.

Windows 7 32-bit Repair Disc.iso 150,194,176 bytes ed53ff0a3acb103a9f6137f76c60e2ff
Windows 7 64-bit Repair Disc.iso 274,247,680 bytes 8dff9265a39a2e0119c8d015e601f8b4

I can't be 100% sure where I got those, because I didn't bother to include
source information when I made up file names... I never expected to be
vetting them I guess.

So the best bet right now, might be to try the techpp link above,
which was suggested indirectly by another poster. It's a
bigger download, but less dodgy and less physical work.
(The download is from sites selling Windows.)
Burn a DVD and then boot with whatever one of those
links on the page is working.

Write your own bootsector. Run bcdedit.exe from a command prompt or
google up EasyBCD.

NOTE: I really can't recall what you need to do to fix your boot with
bcdedit.exe but EasyBCD is pretty self explanatory.

Hi Paul.

I have three disks that I burned immediately after getting this Acer
machine; they're labelled "System Repair disc", "Acer Bootable disc" &
"Acer Backup Manager disc". All of them boot and go through the same
process;


Loading SMARTDRV

Detection RAMDRIVE

Set COMSPEC = C:\COMMAND.COM

SCANNING DRIVES LABELS

HDD = NO_HDD:

BACKUP = NO_BACKUP:-

COPYING OS ONLY MASK FILE

Extracting MSTOOLS

Checking CDROM DRIVE

CDINST Version 3.00

Checking for ATAPI Drive



and machine freezes.

Apparently they can't find a hard drive, and then they look to the ATAPI
dvd drive; whereas Win8 and Linux Live find all the partitions,
including the recovered ones; and BIOS shows everything ok.
I have two theories;
1. I have the Win8 partiton currently set as active. Maybe if I unset
that and set the Win7 one as active, that'll do it.
2. It's a similar problem to one I had with Win7 SP1, caused by the fact
that I had totally restored the hd from a backup about a week after I
first got it.

I'll be looking at those.

I also have some other things to try; a borrowed Win7 disc, programs
like EasyBCD and MBRFix. And then, of course, the last resort of
restoring the whole hd from a full backup made a week prior to last use
(together with a few bits and pieces such as latest game settings,
address book taken from the recovered partition).

One possibility comes to mind. Well, to my mind, anyway.

If the rescue disks have no drivers for AHCI, and the BIOS is set to use
AHCI, then the hard drive is invisible to those disks.

The solution would be to enter the BIOS and set the hard drive interface
to use IDE mode, according to my motherboard manual.

There are other possible modes here, such as RAID or SATA Off.

The above might not be the problem, but it seems worth checking, since
it won't take long. Don't confuse this with "Oh, yes, I'm looking over
here because the light is better".

Problem solved with a Windows 7 installation disk. The Repair function
worked superbly well and quickly. It rebuilt the boot details for both
OSs, put Win7 back on C drive and set the partition as active boot.
Whether it would have worked without me having rebuilt the partition
tables using TestDisk, I can't say. I suspect not.

One interesting point is that the Win8 partition hasn't been allocated a
drive letter under Win7 and doesn't show up under My Computer, but is
fully accessible to Disk Management. Under Win8, however, the Win7 one
has been allocated a drive letter. I suppose that is fully rational,
given that Win8 must be regarded as an improvement (?upgrade) on Win7,
and people would want to reach back for old files.

Thanks for all your time and guidance. It's much better to go exploring
in company, and yours is very helpful and giving. I'm going to post a
short summary of the two simple steps out of the problem, for others to see.

Welcome, Gene, to the frontier-busters' thread. We're treading where
angels fear to go; in the footsteps of Ernest Shackleton, Christopher

All aboard that's going aboard! This ship is not the Titanic!

I've changed from AHCI to native IDE and tried the recovery disc, but
same problem. The BIOS settings all look as they were when I bought this
box and burnt the discs.

P.S. Main problem solved. See above reply to Paul.

You are so full of it. You did not get back your partition and that is as sure as I
am typing this. If you did then you are way smarter than all the MS people
(Engineers) in Building 3 at the Campus who are working on the Win 8 project. You
wanted to look smart and good and not give in after all your posting in this thread.
Once a partition is eaten up by installing Win 8 you CANNOT get it back period.

Post the log created by Win 8 when you got back your partition and not a new one
that you are able to set. I want to see that. You probably cannot because it did not
happen and never can happen if Win 8 ate your partition which it did.

It didn't "eat" any partition. It merely deleted the table. But I know a
thing or two, so I left the space untouched until I could research
restoration.
If you want to thank anybody then thank Paul. He not only stuck by me
but he held my hand and guided me through.

It was restored not by Win8 but by TestDisk + a Win7 installation disk.
You tell me where the logs of those things are and I'll gladly post them
here.

I have been in a position where I lost stuff and was able to recover it,

I'd done until the time when I knew I was going to get it back. I'll
