How do I flag a partition as bootable?

I'm trying to install Ubuntu on my old Macbook Pro. I can't get it to work.
1. This is what I did first:
I boot my portable up as a hard drive. I do this by holding down T upon startup, and see it as a hard drive on my working computer.
2. This is what I did second:
In the terminal of my working computer, after having created a disk image from the Ubuntu ISO, I typed sudo dd if=/path/to/downloaded.img of=/dev/rdisk3 bs=1m
After rebooting the Macbook Pro, it automatically launched the Ubuntu installation program and everything went smooth. Until it was time to install, where it (of course) failed due to the destination being the same partitition as the source.
3. This is what I did third:
I made two partitions on my Macbook. One 1gb partition and a second one for the rest. Now, I tried the same thing but put it on it's own partition. sudo dd if=/path/to/downloaded.img of=/dev/rdisk3s2 bs=1m
After rebooting the computer, I get a blinking folder with a questionmark on it. When I try re-booting and holding down the options key, nothing happens. It doesn't find any bootable partitions.
4. This is what I think I need help with:
Is there any way of flaging the disk3s2 partition as bootable, so that the computer boots from there just like it does when I have only one partition (see 1)?
Additional information:
I can not boot from a USB nor from a DVD/CD due to many hardware errors on my computer. It pretty much has no working ports except the one

Hi ..
Apple Mail does not support that feature.

Drive Preparation
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 GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

"no primary partitions marked bootable" partition error

Hey,
I tried Arch some time ago and liked it, then I became curious about other distribution and checked them out. Now, I'd like to return to Arch, but while installing, I had trouble partitioning my harddrives.
My whole sda is Windows, it's bootable and I don't want it to be touched.
On sdb ist looks something like this
sdb? a bit free space
sdb4 logically Windows
sdb5 logically Linux Swap
sdb6 logically Linux Swap
sdb1 Primary Linux ext 3
sdb3 Primary Linux ext3
I wanted to install the main sytem to sdb1, so I set the bootflag there. sdb3 is supposed to be my /home directory.
When I tried to write this, I got an error:
no primary partitions marked bootable. DOS MBR cannot boot this
What am I doing wrong? This problem didn't occur in the previous releases of Arch. Has it something to do with the 1024 cylinders boot limitation. I thought these times were over.
Can I solve this by setting the boot flag to the free space or the windows partition? Would that change anything on my windows partition?
I'm glad for any answer. I searched this forum, but couldn't find anything similar. Please help.

You can happily ignore this message, but it's still odd that you get it at all, since you have set sdb1 as bootable. How exactly did you plan to set up the boot mechanism for your system?

How to create a second partition on the harddisk?

Hello To All Members!
I recently got some viruses on my laptop. So I had to use my recovery cd to recover my system.
Now the problem is that I asked me for the partition where are the files which are being extracted. I marked it to 30GB.
So, windows is working fine but my Rest of 50GB will not be shown.
I thought that the recovery cd will make a new second partition as well, but it did not. Now how to make some other partitions?
Second question related to first one is how much time i can use this recovery disk. I mean will the windows remain genuine?????
For the partition problem i dont know of some possible solutions cause i needed three partitions, 1st of 30GB(Windows Default) and other two of 25GB.
The Best Solution coming in my mind is to make any windows ME or 98 bootable cd and run fdisk to create the remaining partitions.
But it is makes some new questions in my mind. Do i have to use a recovery cd again? If yes than I will not use this process again cause it will ask for partition to extract files of windows and i will choose 30GB again.
And again it will remove additional partitions.
Please help me and clear the questions coming in my mind..

Hi there,
do know for the UlltimateBootCD4Win? This from CD bootable WinXP-BartPEedition with additional tools gives you the ability to make such things like partitioning, backup or formatting your HDD.
It has many more applications which help you to maintain your system without booting your original OS.
So I think that this CD will solve your partitioning issues.
Heres a link: www.ubcd4win.com/
Just try it and tell me your opinion.
Nice weekend and greetings from the sunny south ;)

How big of a root partition should I have?

I am new to Archlinux and Linux in general. I recently installed my first Arch system but I have not yet installed a desktop environment for I am trying to learn the command line. I was planning on using this weekend to set up a desktop environment but I cannot decide which one to use, so I will try them all (or at least Gnome and Xfce). My question is how big of a root partition should I have to give me ample space to play around including having more than one desktop environment installed at once. I currently have a 20 GB hard drive with my root partition set to 4 GB.
Thank You
Morgan Smith

If you care, here is mine:
Name Flags Part Type FS Type [Label] Size (MB)
sda1 Boot, NC Primary Linux ext2 41.13
sda2 Primary Linux swap / Solaris 271.44
sda3 Primary Linux 39851.49
sda4 Primary Linux 39859.71
Where /dev/sda1 is /boot,
/dev/sda2 is swap,
/dev/sda3 is root, and
/dev/sda4 is /home

How to increase Boot Camp partition without harming both Mac and Windows partition

Hello Apple Support Communities.
I have made a Boot Camp partition with my Mac partition, but the problem is that I am running out of space on my Windows partition. (Darn you, Steam Summer Sale! )
Anyways, is there any way to increase the space on my Windows partition without harming both Mac and Windows partitions. I would prefer if I didn't need to delete the Windows Partition and do everything all over again, as I need to download and set up everything all over again. I also know that changing the Windows partition is a tricky and hard thing, and one step can harm my whole computer, but I think that it is worth the risk.
I really don't care how to do it, anything, from a bootable program, to anything. I just want to know how to do it.
So is there any way that I can increase the Windows partition of my Mac without harming both Mac and Windows partitions? Thanks.

This cannot be done using Boot Camp Assistant. But, you can try using Paragon Camptune X for Mac® – How it works.

How do I mount a partition at a specific mount point.

How do I mount a partition at a specific mount point? For example I see a Vol01 disk image, which is a partition of one of my hard drives, sitting on my desktop. Under the disk utility it says that its mount point is /Volumes/Vol01. How do I mount this partition as a file system at /Users?
Thanks, much appreciated.

why do you want to do this? it sounds like you want to keep your home directory on an external drive. this can be done without changing the mount point of the external. copy the home directory to the external. then in system preferences preferences->accounts, unlock the lock at the bottom, control-click on your user and select "advanced options." In the resulting popup change the location of the home directory to the external.
in general to change the default mount point of a drive see this link

I have recently purchased a hybred 750GbHDD as an upgrade for my MAC Book Pro (Intell Version) I have a boot camp partition to the original 500GB HDD. How can I expand both partitions to fit the new drive?

I have recently purchased a hybred 750GbHDD as an upgrade for my MAC Book Pro (Intell Version) I have a boot camp partition to the original 500GB HDD. How can I expand both partitions to fit the new drive?
I have tried bootcamp and have had no luck due to the fact that boot camp doesn't see the additional HDD space of 250Gb. What am I not doing?

Ouch, well there is a problem.
This is the stack of partitions on your old drive
EFI (hidden)
Lion (50GB say)
Bootcamp (50GB say)
Lion Recovery Partiton (hidden)
This is the same stack on your new drive imaged from the old one.
EFI (hidden)
Lion (50GB say)
Bootcamp (50GB say)
Lion Recovery Partiton (hidden)
Emtpy Space (100GB say)
This is what you want
EFI (hidden)
Lion (100GB say)
Bootcamp (100GB say)
Lion Recovery Partiton (hidden)
EFI has to be at the top of the drive and Lion Recovery has to be at the bottom of the drive.
And you only have four partitions.
You can't move the Lion Recovery Partition or Bootcamp partiton, however you can expand the Lion Partition into empty space below it. (but can't delete or move the Lion Recovery partition)
Your Duplicator duplicated perfectly, too perfectly Likely would work with same sized drives/partitions.
This is what your going to need to do.
You need to move the Bootcamp partition to a blank external drive using WinClone and disconnect. This is so you have two backups of it. (one on your old 500GB drive)
You will need a drive enclousre or IDE/SATA to USB adapter cable for the older 500GB drive and option key boot from it. (some enclosures can't be booted from so check first Other World Computing is good place to ask)
Download the free Carbon Copy Cloner, grab any new files off the new 750GB internal drive to the old 500GB your booted from.
Open Apple's Disk Utility and Erase with Zero option the entire internal 750GB drive and let it rip, this will map off as many bad sectors and improve reliability.
Now use Carbon Copy Cloner to clone the 500GB Lion + Lion Recovery Partitions to the internal 750GB, it will "fix" things and place Lion Recovery at the bottom of the drive where it belongs, give all the extra space to OS X Lion.
Next your going to have to follow WinClones instructions to restore your Bootcamp, likely you will have to recreate the Bootcamp partition first (in Bootcamp) to the size you want and then clone. Likely Winclone may "fix" Windows to recognize it's in a new larger partition now. I don't know you'll have to check as I haven't used it.
When Bootcamp creates the partition it will place it near the bottom next to the Lion Recovery Partition.
As you know you will have to re-validate Windows with Lord Redmond or it expires as you changed the hardware.

How to clone Boot Camp partition when Winclone does not work

The hard drive in my MacBook Pro is failing. It has 2 partions, one for Apple and the other is a Bootcamp with Windows 7.
I tried repairing it with Disk Utility, which did not work. I also ran DiskWarrior, which resulted in the error message: "Directory cannot be rebuilt due to disk hardware failure". I was able to copy my Apple files through DiskWarrior although there were a couple of errors.
My question is how to clone my Bootcamp Partition. I tried making an image with Disk Utility but it failed. I also tried using Winclone and it failed indicating there were hard drive issues.
Is there another way to try to copy the Bootcamp partition? I can boot to Apple so running a program/app or trying UNIX commands might work.
Thank you in advance.

Some previous forum comments I have collected regarding backup of BootCamp.
Acronis 2011 w/ plus pak, didn't work well previously
Ghost 15 - probably not
Casper 6 works for Windows on Boot Camp only
CopyCatX is more lengthy and sector copy so takes the longest.
Paragon Hard Drive Suite 2011 because it works great and they have CampTune
Windows 7 system backup and restore - Apple's goofy HFS read-only interferes with system and file backup.
I have also used Casper, Clonezilla and Paragon but less regularly, Casper failed a few times, I stopped using it, Clonezilla worked but took forever (for me) Paragon (which I have only used twice) was the best but my sample is limited.
I have restored from DU, CCC, SuperDuper and TM, they all worked, TM was slower but not a lot, you can boot from the others, which I prefer.
Paragon HDM 2011 can do either offline or online backups, the difference is that with an offline backup, the entire partition (or disk) is unallocated. In an online backup, the backup utility is running against a partition that may be making changes to itself. When you run CCC or SD! in OS X, you're running an online backup. However, I would recommend (at least for the first backup) that you boot from the HDM recovery CD to do an offline backup. This will ensure that you have an *exact* copy of the parition/disk.
I tried the native Windows backup utility. It worked to backup and restore my Windows partition, but I noticed a "bad" side effect. When I would restore a Windows Backup to my HD, it would corrupt my MacOS boot partition, so I would then have to restore the Mac partition as well.
Winclone allows you to migrate your Bootcamp partition from one Mac to another Mac and make sure Windows will boot. However, if the processor (for example, Core Duo or i7) is a different type, the restored version of Windows may not be supported or be able to run on the new Mac. If you are migrating between Macs that are the same type (MacBook Air to MacBook Air, for example), you will have the greatest chance of success. You can try to restore Winclone images between different types of Macs (for example, a Mac Pro to a Mac Mini), but be aware that if Windows boots but does not reach the desktop, it is probably not an issue with Winclone, but rather the change in processor type.

How do I delete a partition on a hard drive?

I have a 2012 MacBook Pro with OS X Lion (don't know the version), I installed windows 7 shortly afterwards and primarily used that. I've now sold the laptop but need to delete the windows partition and that's where the problem started. The original Mac partition stopped working, so I deleted the content on the bootcamp partition and reinstalled OSX onto that one, now I am unable to delete the original partition so only half of the 500GB hard drive is available to use. Can anyone tell me how to delete the old partition so I can then just re-install OSX so it's ready for its new owner? I also have two recovery HD partitions. Please help!

make it easy, kill 2 birds with 1 stone
reboot holding 3 keys - option, command, r - you should see a spinning globe, if not try again
open disk utilty, select your HD on the left and erase/reformat as mac journaled
exit du, choose install OSX
result - no more windows or other random partitions and a fresh OSX like out of the box

How to deactivate an active partition?

I accidentally made another active partition on another hard drive. How do I deactivate that partition under windows (XP and Vista)?
Thanks!

Hi,
You can use the following steps to de-active a active partition:
1. Open Command Prompt.
2. Type: diskpart
3. At the DISKPART prompt, type: list disk (This command will list all the disks that you have)
4. In the next prompt, type: select disk # ( # means the number of the disk which contain the wrong active partition )
5. At the DISKPART prompt, type: list partition
6. Use the command: select partition # (# means the number of the partition that you want to mark as active)
7. Inactive the active partition with command: inactive
Important Note: We strongly recommend that perform a full backup before this procedure.
By the way, there is a helpful article about disk management, for your reference:
Mark a partition as active (32-bit only)
http://technet2.microsoft.com/windowsserver/en/library/65982abe-19cc-446b-8027-a00bed65abd91033.mspx?mfr=true
It’s about active a partition. However, the inactive process is almost same.
I hope it helps.

How to create and drop partitions automatically?

How to create and drop partitions automatically?
The environment is Oracle 10g(10.2.0.3) on the RHEL4.0 system.
I want to partition the MESSAGE table by date (NUMTODSINTERVAL(1,'DAY') ). One partition per day. Because the table is huge, only 2 partitions (today and yesterday's data) are necessary to be kept online. All the partitions that earlier than the previous day will be backed up and then dropped. I want to make the partition creating and dropping jobs run automatically. How to do it?
Thank you

With 10g, you need to do that yourself. I prefer to create a "buffer" of future partitions - in case the job whose task it is to add new partitions gets held up or stuck. Or the job queue is full due to some problem and it does not get the chance to execute in time.
I dislike your partitioning criteria. I prefer using the date directly and not mangling it to something else. If a specific day has a large volume of data, then another option is to use hourly date ranged partitions. With local partitioned indexes and the date time range used for querying, this can be quite effective performance wise.
As for partitioning maintenance - I use a custom written partitionManager PL/SQL package that provides an interface for adding daily and hourly partitions to a table. Input parameters are for example name of the table, start date and the number of partitions to add. Similarly it provides interfaces for aging partitions - again by specifying a table and a date-time to use as the starting point, back into time, for removing old partitions.
I typically call this code from the actual application code itself - so before a new partition will be used for example, the app code will first ensure that it has a partition to use. This is safer than a separate job as the dependency is resolved where and when it is needed - and not done as a separate task.
For example - you should have a procedure/package that provides an app the means to log a message into your MESSAGE table. As part of an autonomous transaction, this procedure can check if the required partition exists, before attempting to insert a message into the table.
Where this approach is not possible, a DBMS_JOB can be used to create future partitions - but as I mentioned, rather have it add a bunch of future (empty) partitions in case something goes pear shape with the job mechanism.
