OS X :: Installing Leopard - Need To Erase / Restore Disk
Jul 1, 2009
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?

My older MBP is running very slow, and I have tried all the usual ways of making it run quicker - repair permissions, repair disk from Lion recovery partition, remove extraneous files, checking Activity Monitor, etc. etc. Someone suggested reformatting the HD and then restoring from a backup. I have the HD cloned to an external HD with Super Duper, but if I reformat the internal HD and restore from the clone, won't the problems that caused the issue in the first place just be cloned into SD and then restored to the reformatted internal drive, thus defeating the excercise?

When installing Snow Leopard, will it erase my hard drive and force me to start all over or will it just update the software and keep everything the way it is on my Mac now?

My main computer has blown up and I want to install iLife from the restore disk that came with the broken machine on a spare computer but when I try it says that it cannot be installed 'on this computer'. Is there a workaround for this?

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.

Backup is a breeze, no problem there.
Restore is where I got a little confused. I don't have the original Leopard Install disk which I'm pretty sure I need to restore.
BUT I what i need to know is if i could potentially just download a Leopard Install disk in the form of a .dmg file and burn it to a DVD and use that to restore?

I just bought a brand new 13 inch Macbook Pro. Is it possible for me to use the Mac OS X install disk that came with it to install Leopard on my June 2006 Macbook, which is currently running Tiger? I've attempted to do so a couple of times and have gotten an error message.

Whenever I boot up the SL install disk (either plugged in via USB drive or remote disc from my iMac), I select English as my language, "Continue" on the welcome screen, and when I get to the portion where I have to choose a disk to install onto, my MBA's hard drive has a yellow triangle on it and a caption underneath that says "Mac OS X Cannot Start Up From This Disk".
I've used Disk Utility to Verify and Repair, but still get the same result.
My MacBook Air is a 2nd generation machine, 120G hard drive (45G free), and MS Office 2008 installed. Other than that (and all my music and files), it's exactly as it came from Apple when I ordered it.

i have looked all over, and i cant find a simple way to clean install with the SL disk. The screen shots i've seen on engadget shows just "update".
I currently have leopard installed, and time machined everything. I just wanna clean install snow leopard, then navigate into my time machine folder via finder and manually bring over a few files.

I have a MacBook Air and just bought snow leopard. While I was trying to install it (through the use of the optical drive of my mac mini), a message came up "the disk "macintosh HD" needs to be repaired". Go to the computer with the mac OS X install DVD, open 'remote install mac OS X' (located in the utilities folder in the app folder) and follow the onscreen instructions for restarting your computer using the DVD. When the mac OS X installer opens, follow the onscreen instructions to install mac OS X. during the installation, the installer repairs the disk automatically". I'm worried about losing files on my macbook air (and do not use time machine) so should i be backing my files up?

My hard drive recently crashed. I just bought a new one and installed it myself. Now it's simply a matter of reinstalling the operating system, which is where I'm having trouble. I insert the Snow Leopard Install DVD into the drive. I power on the computer and hold 'C' (I've tried Option too) to boot from the disc, but it doesn't work. It spits out the disc after a few seconds, whether I hold 'C' or not, and then it gives me a folder icon with a question mark in it in the center of the screen, the same thing it showed when my hard drive first crashed.

I purchased a copy of SL that I want to install on my MBA. I know that Leopard can be installed using the remote disk feature since my MBA doesn't have a DVD drive. problem is that I can't find anywhere saying that SL will support that function. Although I did see that the minimum system requirements require a DVD drive, but it doesn't say anything about a remote drive.
I'm sure it would be stupid if it wasn't supported, but then again you can't installed XP without the SuperDrive.

I have a Macbook Pro A1229 (Santa Clara) with a broken CD/DVD Drive and would like to install Snow Leopard.
I also have a G5 PPC running Leopard. Can I use the MBP in Target Disk Mode through the G5 to install Snow Leopard ?

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 got SMART warning about my hard disk, I got it replaced by a shop, but said I would do OS restore myself. (cant afford cost )Thought it would be simple - but it is anything but. It appears my install DVD is damaged, so was not able to boot with Grey OS install disk - holding the C key.I managed to get iMac to boot up using the old disk - using firewire dock. However I was not able to restore old disk and OS to new disk, Due to IO read error.(this is why I had the SMART warning). So I am unable to get the OS on the new HD using the old disk or the DVD as these are both damaged. The computer is running, so I thought I would try buying and downloading LION - then using the migration tool . The download is still running after 2 days.I went to apple store, and was told that they cannot replace DVD , so I should bring in the iMac = and pay for the restore. Dont wish to do this. As I have the computer and OS running, is there anything I can do to get a time machine restore from another backup disk (USB).

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.
