Vista, unrecognized partition table use fdisk to fix?

I have a NTFS Vista partition and when I boot into it I get a lot of white type on black screens telling me there is an unknown partition located and to use fdisk to fix.
Vista comes up and works fine but I'd like to get rid of those screens.
Any ideas appreciated ...
Thanks ... Ken

Two yrs going back to RC1 in Oct '06 and I've never seen, nor do I have any idea, what you did or have, and whether you have altered or touched the GPT or EFI partitions or USB device.
And I've got 4 internal NTFS drives, most with two partitions, some flash devices, FireWire 800, along with native SATA external.
And never even seen fdisk mentioned.
Maybe you should click on properties and schedule chkdsk for every partition you can and look in Computer -> Manage.

Unrecognized partition table for drive 80 error??

Currently running leopard on a macbook pro.
Formatted w bootcamp and running Windows Vista Ultimate.
Installation went fine reformated drive to ntfs 45gigs.
But when booting into windows I get this error message
"unrecognized partition table for drive 80"
Then the system boots into vista as normal but that error message is annoying.
Tells me to fix bootmgr using fdisk. How do I do that?
Thanks.

I previously had Vista installed under the beta with Tiger and there was no issues at all regarding boot times or error messages. (Boot times being quite nippy considering)
I did reformat the hard drive space partitioned in side Vista installation as NTFS. As I am only a switcher for a year or so I imagine there may be something I am missing but given the text when I try to boot into Vista, it looks to be the boot loader that is erroring and that looks the same as a GRUB loader failing.
I just do not get why a BETA product would work fine, then after a fresh installation of the new Mac OSX 10.5 with the final version of boot camp I would receive errors like this.
I have reclaimed the hard drive space and split the disk again but the same error persists. Previously I was showing off my Macbook to work mates showing how it handled Windows as well as the user friendly OSX. Now all I can show them is a 5 minute loading screen full of non booting Vista as they look at me like some kind of idiot. (Which depending on who you ask is possibly correct)

Ubuntu wrecked partition table. Help to fix?

(Macbook Pro 2013 15" Crystalwell 4 Core, 500GB SSD 16GB RAM)
I should have known that installing Ubuntu next to Bootcamp was a bad idea.
So here's what's up... Before this whole debacle began I had two separate partitions on my SSD. The primary partition was for Mavericks with 300GB. The second partition was to a Bootcamped Windows 7 with 150 GB of space. I left 50GB free between the two, which still left me at
disk0s1 for EFI, ~200 MB
disk0s2 for Macintosh HD, 300 GB
disk0s3 for Recovery HD 650 MB
disk0s4 for Bootcamp 148 GB
Here's where my problem began. Genius me decided to attempt to install Ubuntu via live USB onto the 50GB space in between. I have reFIT installed so this wasn't a problem. After loading into Ubuntu and realizing that it wouldn't load into the 50GB space, I rebooted and installed alongside Windows (through the Ubuntu live usb) following the install GUI Prompt.
The installation failed after it got hung on a CRON command and drained the battery from my unplugged computer sitting next to me in my bed (I fell asleep waiting for it to finish, even though it was at 100% battery when it started the installation). When I woke up my computer was dead, so I plugged it in. I started reFIT and booted into Windows after seeing that Ubuntu wasn't there. I was given the "Choose OS" prompt from Windows and Ubuntu wouldn't load, so I said screw it and went back to Mavericks. When I opened my Disk utility partitions table to see where it might have gone wrong....
Great Odin's Raven.
I now had ext4 partitions sitting above my bootcamp partition and linux-swap partitions below it. Absolutely no free space. I switched back to Windows, avoiding the failed Ubuntu OS, and uninstalled wubi from Windows (the universal uninstall for ubuntu, I used the Windows "uninstall application" application from Control Center), hopefully deleting the mess it had made of my drive table.
It didn't.
Since I couldn't delete the partitions back to free space around my bootcamp volume using Disk utility (insufficient hfs+ permissions or something like that), I decided to take a more agressive option. I installed partedMagic onto a live USB and once again rebooted my computer into the live USB. I went in and using gParted removed the partitions in front of the bootcamp volume and behind it reducing them to empty space. Good! Hoping for the best I went back to reFIT and booted into Windows...
"No bootable device -- insert boot disk and press any key"
Well crap.
After some more research into why this wasn't working, I was sure that somehow my EFI wasn't loading the right area of my hard drive. Then I think I found out what happened. I ran diskutil list from terminal and saw this..
IceMan-HomeBase:~ Tim$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            300.2 GB   disk0s2
   3:                  Apple_HFS Recovery HD             650.0 MB   disk0s3
   4:       Microsoft Basic Data BOOTCAMP                148.0 GB   disk0s6
disk0s6. There's the problem. Mac doesn't like anything beyond disk0s4, which is where Bootcamp was originally and where it should be now, at disk0s4.
If it were merely an issue of copying the bootcamp volume and repartitioning the hard drive, that wouldn't be a problem, but even WinClone doesn't like this volume. When I tried to do a copy, it threw an error saying "Invalid partition ID of 6"
Here is my question.
Is there a way to change the IDENTIFIER back to disk0s4 from disk0s6 and save my Windows 7 partition, is there some other way to save my files to a backup and clean install, or is he dead, Jim?
Sorry if this was a little long-winded, but I figured too much information would be better than not enough.
Thank you in advance for anyone brave enough to read this.
TL;DR
Partition table went bogus because of a bad Ubuntu OS install. Windows can't find a bootable device. Disk0s4 is now disk0s6. Possible way to change this?

Problem solved, I used iPartition to resize the partition back to its original size after which I could copy all data off.

Load Partitioned Table using OWB

The instructor of my OWB class said that OWB's partition exchange loading (PEL) requires all of a table's partitions to be in the same tablespace. This obviously is not a good thing for partitioned tables.
Does anyone know if this is true for the current version(s) of OWB (I'm using client 9.0.3.35.3)?
What's your work-around for this problem? SQL*Loader flat-file loading?
David

David,
At the moment there are a number of restrictions for Partition Exchange Loading (PEL). Indeed, one of the ones is the fact that all partitions have to be in the same tablespace. Partitioning also has to be on a DATE column.
If you want to implement any other type of PEL, you could do so... by writing everything into a procedure (use dynamic SQL). Alternatively, use ordinary loading... which of course is less fast.

Create a partitioned table using Round Robin

Hi,
I want to create a partitioned table.
My concern is that if I use round robin now, whether I can create a primary key for this table in the future?
Thanks!

You cannot use Round Robin, if your table has primary keys.
But as you must know , now we can create a HASH Partitioning on the tables with out primary key too, i thought ii would rather test once again and comment:
Please find the screen shot below which confirms that Round Robin cannot be done on table with Primary keys.
Where as the table without primary keys am able to use Round robin. Till here it was fine for me.
Now in the second case where i created a table with Round robin and then later i added the primary key using Alter statement, then am able to have Round Robin on the table with primary keys. ( don't know what does that means )

Partition disk with fdisk and windows can't be installed.

so I have been running ArchLinux for a few days, have successfully trashed my partition table once and lost everything on my systemdisk sh*t happens thats why I have one drive as system disk
Anyway, since all my partitions died I thought I could repartiotion the disk (I had been thinking of doing it anyway). So I booted the ArchLinux install disc once again and then partition my disk something like this:
/dev/sda1 - ntfs (for my windows xp)
/dev/sda2 - /
/dev/sda3 - /home
/dev/sda4 - swap
All partitions are primary since I only need 4. So off I go install Arch, config everything and so on. Then today I decided to install windows, so I reboot and insert my windows disc and press any key too boot from the CD and then Nothing. My computer just stands there black screen my CD spindowns and stops my HD is chewing away like crazy.
I have no idea what to do, thought my disk has been broken or something so I open my computer case and disconnect all disks attach my secondary disk as my only one just to see if the install starts and so it does (but I don't install because it is wrong disk ). Then I thought it might be the sata-cable who is bad (happend before) so I tried another one and my systemdisk again, but no luck. After that I boot archlinux installdisc and clear my entire partition table, recreate one 20gb ntfs partition make sure it has boot-flag and reboot. Still no luck, so back into linux and remove everything on that disk and reboots. And now the installation finally starts but instead of creating a partition during xp-install I reboot linux once again to create it in fdisk, and once again the installation doesn't start. So now I have cleare the entire disk from partitions again and created my XP partition during the XP install.
WHY can't I create my partitions by using fdisk in linux? and yes I did create ntfs filesystem on my partition (mkntfs or what the name was, exists on archlinux ftp install disc)

Yes I do know Windows will overwrite the MBR but that isn't the problem and overwriting the MBR doesn't destroy my partitions just uninstalls lilo (yes I use lilo, to lazy to learn using grub when lilo do the job god enough for me)
My problem is that I can't start the windows install. Here is what I did after ArchLinux was installed
1) Start my computer
2) insert windows install CD when computer is doing the BIOS startup stuff
3) Now I get a message to press any key to boot from the CD, this is from the Windows install CD and I do press the key.
4) Normally I would get into the Windows Install program here But now I Don't, NOTHING happens.
Then I started my search on what was wrong. I have installed Linux many times before windows and I have reinstalled windows lots of times without the need of reinstalling linux or repartition my drive.
In short, after lots of testing my computer does not start the windows install if my first disk has been partitioned with fdisk in linux (havn't tried other partition tools in linux).
EDIT: The windows install starts if I boot into linux and use fdisk to clear the entire drive from all partitions, yes no partitions at all not even one for windows.

Error while creating partition table

Issue with updating partitioned table

Hi,
Anyone seen this bug with updating partitioned tables.
Its very esoteric - its occurs when we update a partitioned table using a join to a temp table (not non-temp table) when the join has multiple joins and you're updating the partitoned column that isn't the first column in the primary key and the table contains a bit field. We've tried changing just one of these features and the bug disappears.
We've tested this on 15.5 and 15.7 SP122 and the error occurs in both of them.
Here's the test case - it does the same operation of a partitioned table and a non-partitioned table, but the partitioned table shows and error of "Attempt to insert duplicate key row in object 'partitioned' with unique index 'pk'".
I'd be interested if anyone has seen this and has a version of Sybase without the issue.
Unfortunately when it happens on a replicated table - it takes down rep server.

wrt to replication - it is a bit unclear as not enough information has been stated to point out what happened. I also am not sure that your DBA's are accurately telling you what happened - and may have made the problem worse by not knowing themselves what to do - e.g. 'losing' the log points to fact that someone doesn't know what they should.   You can *always* disable the replication secondary truncation point and resync a standby system, so claims about 'losing' the log are a bit strange to be making.
wrt to ASE versions, I suspect if there are any differences, it may have to do with endian-ness and not the version of ASE itself.   There may be other factors.....but I would suggest the best thing would be to open a separate message/case on it.

Partitioned table takes more time to load

Hi,
Recently I have been test loading a partition table (Datawarehouse fact table). However, I notice almost 2X to 2.5X jump in timing compared to the non-partitioned table.
The partition is on the TIME Key on the basis of monthly range. Since this key is not entirely consistent (less than 1% cases) and can change sometimes, I have enabled row movement.
Is there anything that you can do to improve timing when everything else remains same?
Regards
Prem

Hi,
When you load data into a partitioned table oracle has to check every record
to decide in which partition store it.
When you load data in a heap table oracle hasn't to check it. All records
are saved in the same segment.
You can save time when you load in partitioned tables using partition
clause.

Unique key on range-partitioned table

Hi,
We are using a composite range-hash interval partitioned table
Uses index - trying to make this have same tablespace as the partitions i.e. local but not liking it
alter table RETAILER_TRANSACTION_COMP_POR
add constraint RETAILER_TRANSACTION_COMP_PK primary key (DWH_NUM)
using index
LOCAL
ora-14039: partitioning columns must form a subset of key columns of a unique index
Without local then fine but doesn't have same tablespace as the partitions and don't want to make this part of partition key.
Tbale range partitioned - this is just a UK to prevent duplicates

[oracle@localhost ~]$ oerr ora 14039
14039, 00000, "partitioning columns must form a subset of key columns of a UNIQUE index"
// *Cause: User attempted to create a UNIQUE partitioned index whose
//          partitioning columns do not form a subset of its key columns
//          which is illegal
// *Action: If the user, indeed, desired to create an index whose
//          partitioning columns do not form a subset of its key columns,
//          it must be created as non-UNIQUE; otherwise, correct the
//          list of key and/or partitioning columns to ensure that the index'
//          partitioning columns form a subset of its key columns

Partition tables replication

Can anyone let me know how to replicate partitioned tables using goldengate.

Hi,
I have enabled replication for one of the partitioned table and inserted few rows which got replicated successfully.
Then i tried to update the rows at source, and i could see that this change didnt happen at target side. Similarly when i tried to delete rows my replicat process abended with an error.
Please check this link where i have posted the output and all. Let me know what can be done, we need to move to production implementation asap if this testing goes fine.
Replicat Abended while rows are deleted at source
Thanks,
Bharat Damarla

Vista, unrecognized partition table use fdisk to fix?
