help.. how not to grubinst


Best Answer DavidB , 21 March 2015 - 08:59 AM

Well, I was able to recover the unaccessible partitions by using MiniTool Partition Wizard Free 9.
In its interface I right clicked on the disk and selected "Partition recovery". I then choosed "Full disk" and then tried with "Quick scan".
You can try with "Full scan" if "Quick scan" doesn't find them.
After that right click on partitions and assign them letters.

If it's unsuccessful you can also try with TestDisk.

Hi guys ....Aaaaagh... I've managed to navigate down sh*te street without a paddle somehow!

Experimented (fool) with 500GB NTFS USB seagate drive hooked-up with "grubinst_gui.exe"
thought I'd install grub4dos to secure FAT32 10GB partition (was secured by password)
now opened.... (was)

After sucessful install the virtual Z:10GB FAT32 drive disappeared and the NTFS drive
now is RAW prompting me to format it!!

It would be a shame to lose the 200GB(?) of used data from it.
It might be possible to retrieve data using salvage software.

With help (please) from your good lovely Reboot.pro members I'd rather find a shorter
solution that will stop me pulling my hair out!

... hmmm have a good laugh at the pic lol (can'nt believe I did this)

One option will be to try to restore the original MBR, using grubinst_gui.

Just tick on "Restore the previous MBR" and click on Restore button.

 

If it was restored, disconnect and reconnect the disk.

I'm afraid I had already messed with it prior by using another setting to NTFS the pic in my first post now reads as:

 

FDD  NTFS 0.0MB and is still raw

Can you explain clearly what the disk partition arrangement was.

Did you use grubinst_GUI or something else (why show a screenshot of something that is not grubinst-GUI (bootice??).

What exactly is this secure FAT32 password-protected partition? How was it made?

Before you do anything to the drive, please explain more clearly...

hi Steve6375 the pic is from Bootice app only (not used) used as it showed a difference

 

The hidden partition was made from a security app that throws the partition to virtual drive once passworded

the security app is now toast in the RAW section all I have is the password I do not even know what is is called I have loads of other "giveaway" apps I saved over years on there too lol

 

(if  possible) I was going to de-activate the password unhide  partition then boot the FAT32  with grub then access the NTFS if all worked well!

(I wo'nt be doing that again ...be safe... still need your help pretty please)

Since you know how to use Bootice: open it, select the disk, click on sector edit and then on "backup to file".

Set it like in the screenshot:

Click on backup. Save a copy of the file in a safe location and also post it here.

hi  guys I do appreciate your help sorry about the delay MBR bin file here (saved 0-4 sectors)

hope you find out what the problem is ....this realm it sort of new to me thank you! 

 

I'm not too bothered about the 10GB FAT32 drive partition I found that I could retrieve data even though it was meant to be secure, using FAT recovery software!

Looking at the file, seems to be a PBR, not a MBR.
What's weird is that it's got only 1 sector (512/0x200 B) of data. For a long time the Grub4Dos NTFS PBR is 4 sectors long (2048/0x800 B).
What's again weird is it seems to be a "generic" PBR (no info about the partition). So no wonder the OS can't read the data from partition.
Can you show us each step you did in grubinst_gui?

What tool have you used to partition the disk? Was it "disk management" from Windows? If yes, which Windows version? If not, in that tool have you used GPT or MBR?

 

Late edit: 

I was able to get similar results as you by doing this:
I created a 465 GB virtual HDD, mount it, used MiniTool Partition Wizard to create a 455 GB NTFS partition + a 10 GB FAT32 hidden partition; I then "forced" Grub4Dos installer to see it as a NTFS partitioned floppy by using NTFS instead of AutoDetect at FileSystem.
At this point both partitions are unaccessible.

  Thank you DavidB for helping me, it was years ago when the drive was partitioned, my memory does not serve me too well it may of been formatted using xp. I did have many partitioning software at the time.

  Come to think of it I believe perhaps the security software (name escapes me) created a 10GB secure area FAT32 (size by choice) then it formatted the drive as all data would of been lost at this stage. Yes, then all files were then added.

  The secure area software was a "giveaway" and worked OK; but I found I could access/recover files from that area without a password, it served a purpose at the time; meanwhile I had many files in the unsecured NTFS section.

  Removing the secure area may of affected the NTFS partition files so I kept it!

 

  Your (Late edit:) seems to decribe what I had mistakenly done, I thought the secure area Z: (10GB FAT32) partition was selected to install grub but it may of been "whole disk"(?)

   Realising the error I then turned it to NTFS using grub whole disk (another error) yep I goofed big time!
