How to delete partitions

[hermez1]

Hi
I am in difficult situation. I am working on a client hard disk which is having Linux and windows 7 installation. Disk has invalid partitions & I can access hard disk by any means. So far tried following -

1) UDMA -- does not detect partitions properly , NTFS search has recovered corrupt data.
2) UDMA cant mount hard disk as a task.
3) Dos boot - system does not come to prompt.
4)Various live USB options like paragon /acronis etc.
5) Linux system Rescue CD v4.0
6) Hirens boot cd.
My query is how can I access hardsdisk & delete partitions?
Is there any live usb option which does not mount file partitions ?

Update to my post - Gparted live USB shows cloned disk having no partitions ( complete unallocated space)

1. You stated, you have ACCESS to HDD.
2. You stated, you tried to recover data.
3. You stated, you have no ACCESS to HDD & need to delete partition.

Do you know what you are trying to state?

It is obviously a typo.. he cant access the disk. There is obviously issues witht the disk that need to be fixed, if they are fixable. I think you need to outsource it.

If you simply want to delete all partitions and start again, and there is a problem with the disk itself, then easiest and cheapest is a new one.

If you want to recover data.. and you don't say you do AND it doesn't look like you do otherwise you wouldn't be deleting partitions.. then that's a different story.

Have you tried partition find and mount if you want to recover data?

please give some precise info on what you want to do, what your skillset/abilities are, how far you want to go with this "recovery", and at least the disk model...

cheers

@hermez1, you say you are working on a client's drive and that you have cloned it. This would suggest that you are trying to recover your client's data, so why do you want to delete partitions?

Instead, what I would be doing is examining your clone with a disc editor, eg DMDE (freeware).

Dear all thank you so much for helping me out in this weird case.since there is confusion about the case here are details
1 this is data recovery case,
2 disk is accessible :- no firmware or any other issue.Disk sectors are accessible and it is cloned.
3. I have tried most of the tools suggested, I have dmde pro. But is does not boot even in dos mode.
4.deleting overlapped partitions may solve this issue and I can do logical recovery.

I need a bootable media which does not try to mount Microsoft file system.ideally Linux boot should have been done this but 2 rescue disks refuse to boot.
Thanks again

hi, you can unmount disks with diskpart(the REMOVE command), maybe have a read of:

and things like:

thinking out loud:
can you??
- clone each partition separately and restore just 1 at a time?
- do a physical to virtual disk of each partition separately

I don't understand why, if you have cloned it, AND you cant recover data.. you assume there is nothing wrong with the disk either phy or firmware.

3. I have tried most of the tools suggested, I have dmde pro. But is does not boot even in dos mode.

why not try all the tools suggested. Have you tried partition find and mount?

Dear Haque
Thanks for your suggestions.

As I have mentioned ,I cant even boot from DOS when this disk is connected.
Since tools mentioned by you needs some OS , they are of no use.

******** Cracked the Case *************
Though this was not critical recovery , I was unable to access hard disk by many tools.
Finally I have erased first 10 sectors in UDMA sector edit.This has cleared grub loader and partitions ,so I could mount disk as a task in UDMA ,to run any DR software.

Thanks all
