Lost my Master Boot Record

Hello to all... hoping someone can help.
I was trying to install Bootcamp and the windows installation wouldn't complete (ie. never restarted under XP to go through the last steps of the install). Now I appear to have no boot record that the MAC recognizes.
I have restarted with the "X" key - nothing
I have restarted with the Option key - nothing
I have now restarted with my orig. install discs in the hopes I could use disk utility to correct the problem.
I can see both partitions but I cannot click on "Verify disk" or "repair disk" they do not become active.
Does anyone have any ideas how I can get my machine to recognize the start up disc again? Thanks!

Hi MtlJoe,
You will probably get a quicker response in the boot camp forum located here:

How do I install Lion on an MBP with Snow Leopard 10.6.8, Boot Camp'd XP and a Master Boot Record?

I think this is called "a pickle."
The machine is a 13" MacBook Pro, 2.66 GHz Core 2 Duo w/ 4 GB RAM and a 500 GB HDD.
The HDD has a Snow Leopard 10.6.8 partition, and a Windows XP partition, via Boot Camp. Its Partition Map Scheme, sadly, is a Master Boot Record. I need to reformat it to a GUID Partition Table scheme to install Lion, but when I attempt to boot it from the Snow Leopard 10.6.0 DVD to wipe the drive, it grey-screens. Dead end.
From what I can gather on the forums, I can't boot a 10.6.8 machine using a Snow Leopard 10.6.0 DVD. I can't find my grey DVDs for this machine – still looking for those – but I expect those won't work either, being Leopard-generation?
The machine works fine, for the most part, including the optical drive. Has occassional display and wake glitches. Its HDD is backed up on a Drobo via Time Machine. I also have a 15" MBP Core i7 (with the exact same problem: 10.6.8, XP, MBR) which I can use for Target Disk Mode via FireWire. If I try to wipe the HDD on the 13", using Disk Utility on the 15" via Target Disk Mode, will the 13" then boot successfully from the Snow Leopard 10.6.0 DVD?
I just want to wipe the 13" machine, reinstall a fresh copy of Snow Leopard, then update it to Lion and restore from Time Machine, and never touch anything Windows-related ever again. (And then do the same for my 15", for which I've found my 10.6.3 grey disc. Not sure if that's any more promising.)
Any help appreciated!

Sounds like something is wrong with your disk. Have you tried cleaning it?
The Snow Leopard 10.6.0 DVD is fine – it mounts on both my 13" and 15", and I successfully created an image of it on my 15". I also tried my wife's Snow Leopard 10.6.0 DVD, also clean, which produced the same grey screen result.
Have you tried to use boot camp to erase the Windows partition?
Yep, this is supposed to be the proper way to remove a Windows XP partition from Boot Camp, so this was the first thing I tried. I get the same error as everyone with a Master Boot Record scheme appears to get:
The startup disk cannot be partitioned or restored to a single partition.
Back up the disk and use Disk Utility to format it as a single Mac OS X Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.
So, if I can't launch the Disk Utility from the Snow Leopard DVD, my next best guess is wiping it from my 15" over Target Disk Mode. However, if I try that, and still can't get it to boot from the Snow Leopard 10.6.0 DVD, then I'm stuck with an MBP without an OS.
My conclusion – that 10.6.0 DVDs can't boot to 10.6.8 machines – was based on forum posts about downgrading from Lion. I was wondering if there's a way to create a "10.6.8 restore DVD," and try booting from that. Shot in the dark perhaps.

How Do I Set Up a Master Boot Record(MBR) for 3 Different OS's on 2 hdd's?

I am considering putting three or more OS's on my computer. Would someone show me how to set up a master boot record to give me a choice between Windows XP Professional Edition, Solaris 10 6/06, Red Hat Linux 7 (Fedora Core 5), and possibly Knoppix 5.0.1, Snappix, and Morphix? I want the boot record to be posted in both Windows' BOOT.INI file and in GRUB. Thanks in advance for any help from anyone who knows what their doing about this topic.

Disk Utility won't allow Master Boot Record?

Hello all -
I just purchased a WD MyBook 3TB hard drive for storing our movies on. We had our previous external hard drive (250GB) plugged into our Sony Blu-Ray player and it worked smoothly. But now, I plug in our new hard drive, and the blu-ray player doesn't recognize it.
I tried re-formatting the hard drive as FAT32 (same as the old hard drive), but that didn't work.
The only noticeable thing I see is that the partition map scheme of the WD hard drive is "GUID Partition Table", and the old hard drive's map scheme is "Master Boot Record". I went into Options in the Partition page of Disk Utility to try to change the WD hard drive to Master Boot Record... but it won't let me. It's greyed out. It's there as an option, but apparently not for my hard drive.
What gives? How do I get around this? Thanks in advance for your help!

Alberto you're right, but here's what Lacie answered:

Kindly[/QUOTE]
hi, if you already have the disks RAIDed from OSX then you can't re-RAID them in Windows. The only thing you can do is set it to a RAID, volume scheme and file system that both OSes are able to detect.
Otherwise yes, if you haven't already set a RAID mode on another OS then the disks can do RAID 0 and 1 in Windows.

Can I repair the Master Boot Record (MBR) or Volume Boot Record (aka Windows boot partition) for Windows XP using Windows Vista/7 commands?

I have an SSD drive whose file system is corrupt and unreadable and it's OS of choice is Windows XP SP3 32-bit. I don't have a Windows XP disc.
Is it possible to repair the Master Boot Record (MBR) or Volume Boot Record (VBR) using a Windows Vista or 7 Recovery Disc? What about a Windows PE disc?
I researched around the Internet and found a command in Windows PE called bootsect (http://pcsupport.about.com/od/bios-booting/ht/bootsect-nt60.htm) that can repair both older and new Windows Volume Boot Code (NTLDR or BOOTMGR). The link states that the
bootsect command does NOT fix the MBR. Even the technet site here lists a reference to bootsect and that it can repair the MBR of both old and new versions of Windows (which doesn't appear to be correct). Can I use bootsect to restore the VBR of XP?
If bootsect cannot help me, then what is its purpose? Possible ex: Someone has a dual-boot XP and 7 system, the user uninstalls XP, and then uses bootsect to write BOOTMGR to the VBC.
I would appreciate any insight. Again, I don't have an XP disc. But I do have a WinPE disc and Win 7 Recovery disc and I was hoping I could fix my XP MBR and/or Windows VBR with one of the two.
Thank you.

Master Boot Record is greyed out, so how to use?

How do I use Master Boot Record (in Mountain Lion, to partition an external Seagate Backup+ hard drive) when it is greyed out and I can't choose it? I tried turning off Time Machine, but that didn't do anything. I also tried installing various Seagate software (like HFS4Win.exe) because what I really want to do is use one partition on the drive as back up when I'm using the Mac OS, and the second partition as back up when I'm in Windows 7 (with maybe a third partition for storage for either/both - it's 3tb). I've spent a few days at the Seagate page and nothing suggested there works, but re-formatting the drive with Master Boot Recorded sounds promising, and it won't let me!
If anyone has a solution please let me know! I'm reasonably adept!

Hi Lee,
If "Manage Catalog" option is greyed-out, it may be possible that you are in the "eLive" room. As in "eLive", most of the File option are displayed.
Switch to "Media" room, the option "Manage Catalog" will be enabled.
Then, please follow the steps mentioned in the article to convert the catalog Elements Organizer Help | Creating and editing catalogs.
Please let me know if you need any other assistance.

How to set up Apple Partition Map not to be a Master Boot Record

Hi.
In order to copy Leopard install disk to a flash drive I need format the 8 G Cruzer (on which the U3 was removed) to set up Apple Partition Map not to be a Master Boot Record to be bootable on my Quicksilver G4. I never used partitioning before, step by step please.
W.W.

Hi, motsteve -
Forget booting USB on any G4
USB booting is possible on all G4s and later models starting with the G4 (AGP) models, per -
Article #58430 - USB Info and Benefits of Dual-Channel USB
I think I read somewhere (couldn't find it just now) that the earlier versions of OSX are not USB bootable, so booting to USB on G4s might need to be by using OS 9.
I've never tried USB booting. However, I have made a bootable Zip100 disk for my G4/500 (AGP), using its internal Zip drive. Did it just to see if it would work - it does. There's a fair amount of room left over on the 100MB disk, too.
Intel-based machines are also USB bootable, per this article -

Disk Utility wont allow me to check off "Master Boot Record"

Today I purchased a new Toshiba 3tb external harddrive, I am setting it up for use with both mac and windows however when i plugged it into my macbook (OsX 10.8) it came up as "Read-Only" So when attempting to format it in DU I continuously got an error saying "Invalid Request" I read around online and found an article which I thought was going to help me, which it partially did. I went into the partition tab options and changed it from MBR to GUID but now it doesn't show up properly in Windows without formatting it and when I try that it just goes right back to being Read Only for mac, is there any way to set it back to MBR or a go around to allow me to read and write on both systems?

The drive is setup as NTFS which is read-only to OS X. Do this:
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to MBR then click on the OK button. Set the format type to MSDOS (FAT32.) Click on the Partition button and wait until the process has completed.
Alternatively, you can purchase third-party software that enables OS X to both read and write to an NTFS formatted drive:
NTFS for Mac 10.0.2
Tuxera NTFS 2012.3.6

What is the proper way to record line numbers in Master/Detail records?

Guys and Gals,
Been thinking about this for awhile, but thought it best to ask the people who really know what they are doing.
What is the proper way to record & show line numbers in a Master / Detail record set?
For example, take Master/Detail relationship Orders and OrderItems. Orders has a column Document_Number and OrderItems has Document_Number, Line_Number. Line_Number should contain the row number 1,2,3,4 ... etc. for each row in a document.
Should I ...
<ol><li>Add a sequence and a trigger in the database? The FusionOrderDemo does this, but then the sequence never "resets" and I've got row numbers that keep incrementing. So one document has rows 4,5,6 and the next document has 7,8,9 when they should both have 1,2,3.</li>
<li>Programmatically take care of the row numbers? This seems like I'm asking for trouble. Anytime an insert or delete operation gets done, I'll have to iterate through rows and re-assign row numbers.</li>
<li>Is there a way to assign row numbers in a table iterator (or data collection?) to an entity?</li></ol>
Any suggestions would be appreciated. It's looking like #2 is my only option, but if anyone knows different I'd love the input.
Will

Thank you both guys.
As John said, I believe I'm looking for a gap-free sequence per master record.
The line number of the OrderItems table is the second half of the primary key. The first half of the primary key (DocumentNumber) is the foreign key to the Orders table.
Think of it like line items on an order or invoice. For example, if you were talking to someone on the phone concerning an invoice, you might say, "The pricing for line item #3 is incorrect." In this case, it's good to have a common reference. Or imagine a Microsoft Excel spreadsheet with no row numbers displayed! You'd never get anywhere if you had to explain something over the phone.
If this is tricky to perform, I take it using a sequence and trigger such as the Fusion Order Demo is the best way to approach the challenge for simplicity's sake?

Identifing duplicate master data records using the MDM Import Manager

hi all
I read the Topis "How to identify duplicate master data records using the MDM Import Manager</b>"
i tried to create import maps and to set rules. but when i import them it creates the new vendor records for each rule with rest of the fields blank.
when i import vendor data all the three fields i.e Match rate , match type and match group are blank.
My Question is :
I am getting vendor data from SAP R/3.
In which source (in lookup xml file or data xml file) do i have to include these above three fields and how all the rules will be reflected in repository?

Hi Sheetal
Here we go when do you Import any data (vendor master) please follow the following steps;
1. First of all apply the map to the source data
2. In the Match Record tab there are 3 possiblities
   a.[Remote Key] : Checks the current source rec with
     repository along with all the fields - This is
     default
   b.Remove [Remote key] - by double click the same; and
     choose any single fields like Vendor Number or
     name - Then the current record will be matched
     with the repository based on the field.
   c.Instead of single field you can choose combination
     also.
3. Based on the Match results, match class will be set
   automatically;
   a. None
   b. Single
   c. Multiple
4. Then Match Type
    a.Exact-All the individual value matches are Equal.
    b.Partial-At least one value match is Equal and at least one Undefined; no value matches are Not Equal.
    c.Conflict-At least one value match is Equal and at least one value match is Not Equal.
5. then chek the Import status and Execute the import.
Hope this helps you.
cheers

Master-Details Record

I have a Master and two details records. I need to generate report for the Master-Details record.
I need to include some details from the Master table and some details from each of the detail tables.
For example :
In Master table: Employee_Number
Employee_Name
Company_Code
Company_Name
In Application Detail table: Application_Code
Application_Name
In Non-Application Details table: Non-Application_Code
Non-Application_Name
I need to include Employee_Name, Company_Name, Application_Name and Non-Application_Name in my report. How should I go about creating the report?and may I know what type of report style should I use?Should I use Tabular or Group Above?
Thank for your help

hello,
you might want to start off with a regular master detail layout and then modify the layout manually to fit your needs.
when running throught he wizard, you just select whichever fields you want to display.

Master data records with one key

Hello All,
I have scenario that I need to load the master data records with one key.
For ex--
Cluster            Dcode               version
5000                 DC1                  2008
5000                 DC1                  2008
5001                  DC1                  2009
Could you please let me know possible ways.
Thanks

In your case if Cluster is the key then the underlying attributes data will be overwritten when the same cluster key comes.
as per you example data finally it loads only two records in to the target, since first two records key is same.
Hope this helps.
