MacBook Pro :: Have To Erase Disk To Install A New OS?
Feb 24, 2012
I have a Macbook Pro 2.1 GHZ with 2GB of RAM from 2006 with Mac OS X 10.4.11 (Tiger) and I bought Snow Leopard (Mac OS X 10.6.3). I want to install the new OS but I had some problems with this process. Do I have to erase my hard disk first and then install Snow Leopard? I want to keep my documents on my hard disk and the programs that I have.
I have a MacBook Pro which was originally supplied with OS X10.4.9. I have upgraded using disks purchased from the Apple store to 10.5 and subsequently 10.6. More recently I upgraded to 10.7 using the download from the online App Store. I would like to perform an Erase and Install to get rid of the 'dross' on my hard disk and may do this as part of the 10.8 upgrade although have yet decide whether to wait for this or not.Â
when doing the erase and install, do I have to start from scratch by loading the original 10.4.9 OS X version or can I start at 10.7. If the latter how would I do this given that I don't have a disk as it was downloaded from the App Store?
Info: MacBook Pro, Mac OS X (10.7.4), 2.4 GHz Intel Core 2 Duo
1. To grab all the files I need/don't want to lose (photos, music, documents, etc.)2. Then completely erase the 500GB HD so I can then install it into the new Macbook Pro and install Leopard.(I'll then externally connect the 160GB HD that came w/ my Macbook Pro and add the files I've already copied into that 160GB HD into the 500GB Leopard installed HD in the new Macbook Pro)So, currently my 500GB HD is connected to my Macbook pro and I want to completely erase everything so I'll then have a completely clean hard drive, to then install into the Macbook Pro, add the installation discs and install Leopard into the 500GB HD.
I want a brand new OSX installatetion. What is the best way to completely erase my SSD (to make it brand new) and reinstall MAC OSX (i can use internet WPA secure Wi-Fi to reinstall MACOSX Lion). On macbook air late 2011.
Anyone knows why my external HD (USB disk connected to Airport extreme) does not show up in disk utility? (It sits on my desktop just fine and is fully functional) I' want to erase a partition but now i don't know how.
I bought a used mac and when I erase the disk, afterwards it still shows 2 files and 2 folders on the disk taking up 40+mb of space. What is that? When you erase the disk isn't it supposed to be completely empty?
I've erased and reinstalled my Lion 10.7.3 but after rebooting, all my previous programs are also installed.How do I format and erase my HD completely so I get a clean OS like I had when I bought my Macbook Pro?
I got a new macbook pro. I tried installing windows on it via bootcamp...To cut a long story short, I messed up the system. Now the PC doesn't start and when I run the system, the apple logo just shows with the chime. Nothing more. I din't back up anyhting.Â
If the system manages to start, immediately I log on, the computer logs itself off again. Im simply tired of all this and want to erase mac osx lion from my mac book, then re-install it again. How to go about it?Â
I know pressing Command +R then going to recovery will open recovery. Then I click on disk utilities. But then, selecting which hardisk to format?
My hard disk had no partitions, but then trying to format it, I see a larger disk with a different title, then under it, I see "Macintosh HD". Which of them should I select to format to do the job? the main HD or the sub one under it "Macintosh HD"Â
I totally hate this, considering the fact that I have to buy about $60.0 worth of credits to re-download osx lion from the net. My macbook didn't come with a cd you know..
I'm booted on a MacBook Pro from an external drive, and I want to erase the drive inside the MacBook using Disk Utility from the external. For some reason or another, it won't let me do this. When I click on the Erase tab (whether clicked on the disk itself or the volume "Macintosh HD") and try to erase it, it returns with the error:
Disk Erase failed Disk Erase failed with the error: Could not unmount disk.
When I try to install an image onto the drive, I get a similar error, except it says "Operation not permitted." When I tried it while booted with an OS X DVD, it worked fine. As far as I know, I should be able to do this while booted from the external HD.
I am trying to reinstall Lion on my macbook pro, but every time the hdd shows up as 'locked' and when I attempt to format it, it gives me a "volume erase failed with the error - cannot unmount disk" message. It appears as if some files withing the disk are still running but I have no way of quitting them-knowingly. I can specify more if this seems to vague.
I'm unable to erase a disk/volume so that I can migrate. The only thing it's allowing me to do is erase free space. I am using MacBook 10.6.8 and migrating to a different MacBook using 10.6.8.
How do I recover the data after erase the Macintosh HD disk and also reinstall the system?My laptop could not be turned on last Wednesday, but I needed to finish up my assignment and submit on Saturday.I searched online a way to keep my data but the laptop could be fix up.
Under disk utility, I erased the Mac OS Extended (Journaled), then reinstalled the system.It's said that in this way my data will be all kept, but when I finally got my laptop turned on.All my data was gone including my files, applications, and so on.

I have a macbook running leopard and am upgrading to snow leopard. I have a back up from leopard on an external hard drive and I would like to completely wipe my computer, start fresh. However, I no longer have the leopard install disc but I do have the old tiger install disc. I am thinking to revert to tiger to restore the computer's settings and then upgrade to snow leopard. Will I still be able to restore select items from my Leopard back up?
Can't install the applications dvd, it says an error occured and i have to contact the software manufacturer for this. What will i do to have it installed (i life)?
I'm trying to erase my hard drive to sell my MacBook and well I used the drop in disk to help with this. I dont have the gray disks that came with my computer. Any who I ran it erase and reinstall the os and at the last second it failed to install. Now when I start my computer with the disk it'll try to down load the os and it says that I don't have an OS X version 10.4 or higher on my computer. So basically I don't have a operating system on my MacBook. It's empty. It is a white 13 inch MacBook.
I'm trying to erase my SSD internal drive that is corrupted software (Yosemite).I'm booting from an external with 20GB Yosemite OS & 480GB that contains files I've dragged off the internal SSD.I'm getting the error:Volume Erase failed with the error:Couldn’t unmount disk.How can I get around this?
Long story short: I've been having some issues with Leopard (and it looks like it was probably my fault for simply choosing the "Upgrade" option when I moved up from Tiger), and so now I'm looking into a clean install Leopard, which according to all other indications should fix my problem. Now, my initial reaction was to go with the "Archive and Install" option, but since I've been reading more about what people have to say, I'm starting to wonder if I should just choose "Erase and Install", and then restore from Time Machine instead? ...or is there really even a significant difference in the end?
I would like to keep everything as intact as possible, which makes me think Time Machine would be better, but then at the same time I've read stories about people having difficulties with restoring from Time Machine, and losing certain applications/preferences, etc... but sometimes they say it works just fine. So I don't know. But I'd like to get some second opinions before moving forward too quickly and then possibly regretting my decision later.
I just received my new MacBook Pro. It came with 250 gb of hd space. I had to do an erase and install on it because of an issue that came up while using the migrant assistant. So, after doing the erase/install it says that I only have 216 gb of space left? And thats without the applications CD that I have to put in which will be about 4 gb. I believe when I first turned the computer on before doing the erase/install it had about 235?
I'm having a pretty serious problem. I attempted to erase the free space on my HD, as I do from time to time, except this time it appeared to hang/freeze at the end, when it gets to the part where it creates a temporary file. I waited for several minutes and it didn't move. I tried clicking the skip button, but that did nothing either, so I force quit Disk Utility.
The problem is, it left the disk at "Zero KB" of free space, effectively making my computer inoperable. I was in the process of studying for a huge exam tomorrow, and am currently flipping out.
If it matters, I'm on a Macbook Pro 2.33 GHz Core 2 Duo, running 10.4.
I really don't want to have to reinstall the OS and import the old files, but my real fear is that I will have to do a fresh install of the OS.

I am having trouble erasing DVD+RW discs. When I insert a used disc and try to erase it in Disk Utility, the process seems to complete almost immediately, ending with OS X asking me if I want to mount the inserted blank disc in Finder. However, if I eject the disc and put it back in, everything is still on there. (detail: When erasing, there is usually a short interval where a striped progress bar is shown, after which a "normal" progress bar is slowly filled as the disc is erased. However, for me only the striped progress bar is shown--the "normal" progress bar is skipped--and then OS X says erasing is done.) If instead of ejecting the disc I choose to go ahead and burn something as if Disk Utility has actually erased the disc, I get a laser power calibration error.
I need to erase a disk I bought with NO formatting. I shouldn't have initialized it when I connected it, and now I need to erase it but do NOT want to format it.
I've been trying to use diskutil eraseDisk %noformat% /dev/disk1
Like the diskutil eraseDisk instructions tell me to, but it won't take.
I have been reading that the erase feature on OS X's disk utility will not remove file slack. If I erase the entire drive using one of the security options (Zero-Out, 7-Pass, or 35-pass),
I recently installed and uninstalled a few versions of linux on my imac. After installing some versions i realized I was going to need more space, so I went back into mac OSX and have been trying to add a new disk partitions with more GB.
i was Erasing Free Space in Disk Utility, after a while I needed to Force Quit another program but I mistakenly quit Disk Utility and now it says I only have 3.1 GB space available when it should be around 270 GB available. I'm sure Disk Utility said it was 'Creating Temporary File' at this time this happened.
I'm now also getting a message which states I need to clear out space on my start up disk.
Sso something went wrong when I was installing leopard and it said that I had to erase and restore the disk or something like that. Now I know exactly how to do this but what I am wondering is will this completely delete everything on the disk all the applications and such? It has tiger on it right now so after I erase it will tiger be gone so i wont be able to put leopard on? How does this whole erase thing work?
