Mbr corrupted?

Amd / XP2000
April 19, 2009 at 08:54:24
Specs: windowsXP, 1.6ghz/1gig
I think the Master Boot record is somehow corrupted on my amd machine. After the list of what is installed I get 'searching for Boot Record from IDE-0..OK
Boot failure from previous device..
searching for boot record from IDE-1--OK
Invalid partition table'
I was first trying to format a hd i had plug into the primary cable so somehow(i don't know how) it corrupted something. The drive i was trying to format was faulty and i wasn't able to format it so I unplugged and put the original primary drive back in. Then I saw some fix where you use a win98 boot floppy and use fdisk /mbr I think but that didn't work. I think I went into fdisk and maybe that is when the 'invalid partition table' error started to happen.
Can anyone help me with this silly mistake?
I have two hard drives btw.

"...and put the original primary drive back in..."

... does this drive have anything on it?

.. ie a "partition" ..? .... files..? ... an os ..?

... Fdisk /MBR ... will take out the Master Boot Record

... boot up with that disk again and type FDISK [press ENTER]

.... (Y) ...yes

... then select "option 4" ..display partition information

... post the contents here

.......ps.... ....unhook the other drive for now

In addition to the above do you have a WinXP CD?

I have windowsxp(on the primary drive) on that computer. The secondary drive is just for storage. I don't think I originally partitioned anything. My knowledge of partitioning is nil so I haven't done it.
OK I am in fdisk and number 4 is selected. It says 'Display Partition Information
Current fixed disk drive:1
No Partitions defined
Press ESC to continue'

Other drive is unhooked!

Hi onthehill-I have the winxp cd but I can't seem to work out how to get the recovery/repair mode. I saw somewhere that you press R but nothing happens.

... ok you have "zippo" on that drive

... boot-up again with that disk this time select option 1

... create dos partition or logical drive

... let it do its thing "y"... use all space "y"...make active

... when it asks to give it a name just press [ENTER]

.... that will create one partition ...next boot-up with the xp cd
and "format" and "install" a fresh xp

The first link below expains how to use the recovery console. Try the command fixmbr. If that doesn't fix the problem then use testdisk from the second link bleow. Be sure th thoroughly read all the tutorial and help files before attempting to use it.

mavis007....what do you mean by zippo? Do you mean I somehow erased everything? I have windowsXP on it! Oh or do you mean there are no partitions? Gee i hope I don't have to lose my files? Sorry first time this has happened to me. I was tired when this happened. I don't know what I did exactly now.

OTheHill-OK will read the pages later today and see what can be done. It is not good to miss steps. Thats how I got in this mess in the first place.

... Current fixed disk drive:1
... No Partitions defined

... it is possible to to revive the partition again. but I ca'nt think of any "free" software "off the top of my head" that will do it!!

... there more than likely is !!

... so what do you think is best ? ... revive it or clean install?

... you got all the drivers?

.... boot-up with it ...and see if there is an undelete partition option.

...NOPE it wo'nt let you ....<<< edit

I have got the Ultimate Boot CD but I am not sure how to use it. I don't have enough usage to download anything big right now or really ever. My speed has been stepped down as I have killed the usage on my net connection which is easy to do in Australia. The UBCD has heaps of tools and maybe that is where I stuffed up with it. http://www.ultimatebootcd.com/ I probably have an old version of it too. Now that I have had enough sleep I think I erased my primary drive.....silly me. I do have all the drivers as that is the only computer I ever bought new. All the rest of my machines I got from people who were upgrading. Fun really building machines and you don't have to worry if you stuff up as everything is free.

Refer back to #5. As I stated, if recovery console can't fix the mbr then testdisk should be able to.

If you have no defined partitions then fdisk will not show any. That only makes sense. Doesn't mean there isn't any data there.

... there is no need to worry about "MBR"

... the fdisk /mbr ... is ok @ this stage infact make sure it was done!

... a clean xp install will be ok with the mbr "zapped"

If you are not trying to recover any files then as mavis has said just install Windows.

I know everyone is trying to help me a lot but I have tried another way. I put in another hard drive as a primary(it's not one of the drive I have discussed above-from a spare machine I had sitting around) and hooked up what was formally my primary drive and it is now a slave. I haven't put the jumpers in and wasn't sure i had to. I think it is like a cable select situation? Anyway I installed windowsxp on the primary and left the secondary along in that process. Now I am in 'disk management' and the secondary is there as Disk 1 and is unallocated. It is not listed at the top where the New Volume (C) partition is so I am not sure where to go from here. Do I have to format the second hard drive or can I view/transfer files off the drive? I have been googling to find out but nothing seems to match my situation.
Sorry I have taken so long but had to get my linux machine back online as my modem died. Too long a story that one but it is good I am online again!

You are still in the same situation. Try testdisk, recovery software, or simply partition and format. For recovery software look at the link below courtesy of aegis1.

PC Inspector (freeware)
http://www.snapfiles.com/get/pcinsp...
Zero assumption Recovery
http://www.z-a-recovery.com
The demo is limited
It will only recover 'up to' four folders per run
But you can make multiple runs
IMO the best, but not free
GetDataBack

I decided to download pc inspector anyway as it is only 6mb or thereabouts. Trouble is I am not sure how to use it and it is telling me the drive is not mounted so it is useless to me. In the system info section it is not showing the secondary drive. The select drive section was confusing to me as it says:
New Volume on fixed disk #1
New Volume on windows drive C:
I suspect there are two partitions on that drive I made primary for now. On the drive it says it is 80gig yet when I was formatting for the install of windows it only mentioned 32gig. Geez I am getting no where.
OH I just found another section of pc inspector that shows something different:
fixed disk #1 (31.49gb)
fixed disk #2 (38.29gb)
windows drive c: (31.49gb)

Ah so that sounds like there is another partition. Yet when i used 'disk management' in windows it didn't show it. It is showing a diskO and disk1 so maybe that is it.
