Make a disk bootable

For the live of me, I cannot find an appropriate forum.
Moderator: please move this question to an appropriate forum.
I have a PC running Vista ( Win7 has same issue )
I have A USB to IDE converter.
I place a Solid State Disk on the IDE converter.
I have a utility that writes to the SSD boot block. It is a DOS 6.2 application that runs in a command window.
I swear this worked last week, so there must have been some auto-update that changed things.
Now when I run the app to write to the SSD boot block I get
"Unable to lock for exclusive access. Another application may be using the drive."
Well, no there is no other application using the drive.
Even when I choose "ignore" the application claims success at writing to the SSD boot block, but it did not.
This worked last week.
Now what?
How do I "LOCK" a device for exclusive use? LOCK is a DOS command available in DOS, Win95, Win98, WinME but not in WinVista, Win7.

Hi Boyd1,
I’m afraid that it is not the correct forum for this issue, since this forum is to discuss:
Visual Studio WPF/SL Designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System, and Visual Studio Editor.
I am moving your question to the moderator forum ("Where is the forum for..?"). The owner of the forum will direct you to a right forum. Thanks for your understanding,

Cannot reinstall Tiger : installer stuck (cannot make disk bootable)

Good afternoon experts,
I am writing to you here as I have a problem with the Tiger installer which suddendly stops when trying to install on a prepartioned disk.
First, some background information : I have a 20' iMac Intel machine which I bought on February 06 (well designed machine, happy with it so far). The thing is, I have had serious crashes and lockups using the UB version of VLC (media player) which led me to hard reboot the machine several times. Despite the journaling on the disk, some of my filesystem was corrupted, seemingly beyond repair (some apps did not even boot, nothing happened when I plugged in an external disk, etc). Scanning for disk errors and permissions problems revealed that a lot of files had been damaged ("extended allocation" error) in both the system and in my applications.
As I did not know what to do (I should have asked first here whether it was possible to reinstall only parts of the OS using, maybe, a package manager), I synced my backups and went for a reinstall.
The thing is, the disk is already partitioned, as I also run Linux on the machine (updated firmware and repartitioned the disk w/ BootCamp; worked well). It contains, in that order : the hidden EFI partition (fat32), the macOSX HFS+ volume (where I want to install), Linux swap partition, HFS+ partition (for use w/ rEFIt, the EFI bootloader), and two Linux ext3 partitions.
The install starts fine (booting from the DVD which came with my machine), the macOSX volume is formatted but the installer just then stops. Looking at the logs, I can see that it is because it cannot make the volume bootable (this is what the error message says). Note that it correctly read the partition table/EFI partition scheme as it gives me the correct partition types I have presented above. Also note that I cannot do an "archive and install" procedure, seemingly because I have insufficient space (6GB free on the volume); the installer does not give me any choice. Finally, I can still boot into Linux holding the 'Alt' key and using the builtin volume chooser to start on the second HFS+ volume.
I am asking for help to you gurus, to know what to do here. I was think maybe something like using the shell to do a manual 'bless' would solve the issue; I would like however to be sure before proceeding. Otherwise, is there a manual installation procedure (as there is for instance on the Debian installer, allowing to skip/redo some install steps)?
Thanks for your help experts,
Vincent
PS: I am going to see whether I can collect the logs and post them here.

Hello back,
As I did not find a way to attach my logs, I am posting the most relevant parts of it here.
This is where the installer erases the volume and fails at make the disk bootable :

PLEASE HELP !!!!

Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.

How can I make a drive bootable without losing data on it?

Is there a way to make a second internal drive bootable without losing the data that is already on it?
The second drive was created under Panther 10.3.9. My main internal drive has had a clean install of Tiger 10.4.3. The second drive used to appear in the start up disk list when I was running 10.3.9 on the main drive. That is, it used to be bootable under 10.3.9. No kidding. After the main drive was given a clean install of Tiger, the second drive disappeared from the start up disk list. Please note: the second drive remains completely accessible when I am running off the main drive in 10.4.3. I can even use the few applications I had placed on the drive. It appears as separate drive under disk utility.
I assume the second drive was installed as slave. (Both it and the main drive were independently bootable under 10.3.9.) It is not locked. "Ignore ownership" is not checked. The system has read-write privileges. Admin has read-write all others are read only. I am the only person who has access to this machine. It is not networked.
I tried to ask this question a few days ago, but I think the way I phrased it confused the issue. My real question is NOT how did this get like this? It is can I make a drive bootable when it already has data on it?
Thanks
G4 Panther & Tiger Mac OS X (10.4.3)

Hi,
Thanks for your reply.
You replied:
the drive that you cannot
boot from is a separate physical hard drive from the
internal drive with 10.4.3. Is that correct?
Yes.
Have you used System Preferences > Startup Disk and
looked to see if the 10.3.9 system shows up there?
Yes, I have looked and it's not there.
I got the impression that you have backed up the 10.3.9
disk and that you do not really need the data there.
Yes, I backed up a drive that was bootable, but then it lost its "bootabilty" and what I got was two non-bootable drives--the original second internal drive that I'm asking about and the back-up of it. I want the data on the drive and I wan the drive to be bootable.
One thing that you might try when you are booted off
your 10.4.3 system is to use Disk Utility, select the
other disk and do a Repair Disk.
Done that and it says there is no problem. Nada. Zero. It just won't boot, no more, no how, no way. BUT it remains fully accessible--I can access all my info. It's just become a storage drive that cannot be booted. Go figure.
reformatting means
destroying the data on the disk.
Yup, which is why I asked my original question. Does anyone know if there is any way to make a drive bootable without destroying the data on it?
I suspect the answer is no (given these particulars), but I thought some wise super-techie out there might have a trick up their sleeve.

How to make boot disk for MacBook Pro with Mavericks pre-installed

Hi -
I recently bought a new 15" MacBook Pro with Retina Display, which came pre-installed with Mavericks (10.9.0). I want to make a bootable USB disk of the system software, and have successfly used DiskMaker X (formerly Lion DiskMaker) to make the USB boot disks for Lion and Mountain Lion. In those cases, however, I was running earlier versions of the OSX, and downloaded the new OSX version -- Lion and Mountain Lion -- from the App Store in order to make to make the disk. In this case, however, Mavericks was pre-installed, and I was unable to download it from the App Store (an alert said that it couldn't be installed on this computer... presumably because it was already installed). I would apprecite any suggestions as to how I can create the boot disk without the ability to download Mavericks. Thanks very much for any help anyone can provide.
Shelly

Open App Store and locate the full installer download file (5.29 GBs) for 10.9.1. Download to your computer.
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
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.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.

Why can't I make a disk Image??

getting Leopard tomorrow. system working great. plan to do an "upgrade installation". backed up all my files (106GB) to an external HDD. so I think I'm ready....
question is - why can't I make a disk image of my "Macintish HD"?
it starts to create the image but Disk Utility comes back and says "Unable to create disk0s2.dmg. Resource busy."
I thought it might be a good idea to do a "complete system backup" just incase something goes wrong with the "upgrade installation".
Since it didn't let me, I just dragged-n-dropped the Users folder to the external HDD, so I got my files backed up.
curious why I can't make a disk image of my WHOLE HDD. can someone enlighten me....
thanks, chris

How to make a disk image of a DVD to Playback in IDVD Player?

Is there a way to make a disk image of a DVD so I can play it with IDVD Player? I made a DVD image from Disk Utility and got a .dmg file, I then copied the contents of the DVD to the image. iDVD doesn't recognize it. So I then converted this image to a DVD/CD Master .cdr file with Disk Utility, but this isn't recognized by iDVD either. I am running OS 10.4.11.

One can burn a disc image thru iDvd or apple's disc utility but it is Not possible to play a disc image thru iDvd to the best of my knowledge. However a disc image burned thru iDvd will play exactly like a typical dvd when apple's dvd player app is used for playback. You may need to navigate to the video_ts folder (w/in the disc image) in order to play the image.

Unable to make recovery disk on in pavellion g62016 .dat file is missing in recovery drive

unable to make recovery disk on in pavellion g62016 .dat file is missing in recovery drive
can i use the .dat file of another same notebook
what is significance of ,dat file

Hello shail11. I understand that you're having some problems creating a recovery disc. Is this correct?
You can not use another .dat file. The recovery media is specific to a certain notebook, so using another computer's files will not work. If you're running into issues making a recovery media you could attempt to perform the recovery from the BIOS. Here is a document which outlines the process. ALL data not backed up before performing the recovery will be lost.
Let me know if this helps; have a great weekend!
Please click the white star under my name to give me Kudos as a way to say "Thanks!"

How to make hard disks hidden?

I Have 2 HDs and i want to use them on my macbook via network and to do it, those disks needs to stay connected to my sister's mac pro. This disks have confidential and work files that no one can't have acess. Does exist a way to make this disks hidden on my sister's mac and mounted only on my macbook?
One of this disks are used to keep my files and the other one is used by Time Machine backups.

You can change Sharing & Permissions on those drives so that only you can access them. Right click the hard drive icon and select Get Info.
In the bottom of the new pane you have to click the padlock and authenticate. Sharing and Permissions should show you have Read & Write privileges. Change "everyone" to no access.

Make a disk image of a drive with a bootcamp partition?

Forgive me if this is a silly question, but I'm not evern sure what to call what I'm trying to do so I had a hard time finding information on the topic.
I installed Windows 7 on my imac using bootcamp and I love it, everything works great! I spent several days installing everything on both partitions and I'm very happy with the way everything is running. I would like to "clone" or make a disk image of my hard drive. This way if I ever need to reinstall things or have a hard drive issue, I don't have to reinstall everything.
To be clear, I'd like to copy both the windows and mac os partitions together in one step, not make seperate backups.I'm not sure this is even possible.
I backup my files regularly on external drives so I'm not interested in anything that maintains a system of backups or anything like that. I'm looking for something more like a computer lab at a school would use to reformat and and do a fresh install of all of the software easily. Preferably I'd like something free, but I'll pay for something if it makes life easier.
Thank you for the help!

I know it's a lot to absorb (I've been doing these types of things for over 20 years), but if you take it slow, you won't have problem (like restoring over the wrong partition).
The first thing you should do is to create Recovery Media using the Recovery Media Wizard. This will give you a boot CD with all the Paragon tools on it. It your partition or disk goes south, just boot from this disk (hold down 'C' after the gong or hold down Option key and wait until the boot manager appears, then select the Recovery Disk). You cannot restore a image copy to a disk where you're running the OS, so the way to do a restore of a partition (or entire drive) is to boot the recovery disk, point to the partition/disk image, select the partition/disk to recover to, then start the restoral process.
For my Boot Camp partition, I prepared a Backup Capsule following the directions in HDM 2011. Since I have several 250 GB SATA2 drives just lying around from another server installation, I figured it would be best to use a pre-made Backup Capsule. But you can use just old any drive in any format, or even laser media (I wouldn't recommend that unless you want to store your backups offsite).
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.
Since this is you first time backing up your partition, I would suggest using one of the Backup Wizards. They'll guide you through the backup process and keep you from doing something wrong Similarly, use the Restore Wizard to restore your partition/drive.
To back up a dual-boot Mac to an external USB drive, do:
1) Boot from the Recovery Disk (I'm assuming that the backup hard drive is attached before you reboot)
2) Select Paragon Hard Disk Manager
3) Launch the Backup Wizard by selecting Wizards > Backup Wizard
4) Select the Mac hard disk (not the partition) where it asks "what to backup"
5) On the Backup Destination page, select "Save data to any local drive or a network share"
6) Hit the radio button for the "Save to local drive option" (unless you got a boatload of DVD's )
7) Select the external USB drive as the backup destination
8) Look over and correct the name and comments
9) Hit Next to start the backup
When it's done, you have an entire copy of your Mac's HD saved to external media.
If you need to recover your HD, just run the Recovery Wizard and reverse the process.
I hope this helps to get you started. Good luck.

I want to back up my photos to disks, but if i save my masters will it save tyne edits that i have made to the referenced photos? or to i have to make 2 disks, one for masters and one for referenced?

Hi, i just got my mac air and moved my photos from picassa to aperture. I save my masters to an external hard drive. I also back my photos up to a disk once a month. my question is if i burn the master photos to a disk will it save my edits to the versions? or do i have to make 2 disks for each month? I have had external hard drives die on me before and I just want to make sure they are backed up correctly to disks...thanks for any help!

Read the User Manual chapter on Backing Up. The User Manual is good: logically presented, easy to search, and concise. It should be the first resource you turn to in searching for answers.
Your Library contains your Images' Versions (these are just text files -- a detail that can be ignored for the time being). Since your Images' Masters are Referenced (= stored outside the Aperture Library package), you must back up both your Library and your Referenced Masters in order to have a complete back up of your work.
Search the forum for some helpful comments re: backing up to plastic media v. to hard drives. The consensus is that one's time and money are better spent backing up to hard drives at present.
Since your Referenced Masters plus your Library makes one complete back-up, there is no reason not to put them on the same drive.
I recommend keeping 3 copies of your work. The active copy, and two back-ups, with one kept off-site all times (never have all three in the same location). I also recommend keeping screen-size Previews of all Images, just in case there is some corruption or other reason that makes it impossible to create new full-size Images from your Versions (again, Versions are just text files -- they are not image-format files).
