OS X :: Installing Snow Leopard - Mac Cannot Start Up From This Disk
Jul 1, 2009
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 ?

this isn't an isolated issue - there are threads about this over at Apple and InsanelyMac: I'm unable to install Snow Leopard. When I run the installer, it'll tell me that "Mac OS X cannot be installed on "Macintosh HD", because this disk cannot be used to start up your computer" (Macintosh HD being my OS X volume, obviously). I'm seeing this issue on a relatively new 1.8ghz Macbook Air with a 128gb SSD - however, as far as I can tell from the other threads, the problem also affects iMacs and Macbooks.
Some people apparently attributed the issue to a PGP installation they had on their harddrive. Others found a file called backup.backupdb in their root - deleting it fixed the problem. However, most people don't have any of that installed on their computers and the upgrade still won't work. - if anyone has found a solution to the issue, please let me know :-( I'm stuck here. I don't have an external drive for the MBA and booting from a network drive has never worked on this particular machine - so I can't do a clean install, either.

I am most certain that this is the case: foolishly, I didnt leave much free space and now the disk doesnt want to mount. I tried the single user mode, I also booted from DVD, they appear but the disk utility shows the disk but I cannot repair the disk, because it is unmounted. I tried the basic commands in single user mode, no effect either. I still cant get over the blue screen with the apple logo and a circle running. I need to free up some spasce. Unforetunately, important files were not backedup, so I really cant delete the whole disk. I need to delete specific files. I dont know where are my big files located - so, how do I orientate myself among the folders? Lets say I would delete my itunes libary, which I would later on renew thanks to the back/up, how would I delete them?

I have a Snow Leopard Install Disk for the 13-inch Macbook Pro model.I also have a 21-inch iMac. I have OS X Lion installed on both. I have Snow Leopard installed as a partition on my Macbook Pro, which I installed via the install disk. I want to do the same thing for my iMac but I am unable due to (seemingly) my install disk is for a Macbook Pro and not for an iMac.

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.

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?

I have a tower Mac Pro with Snow Leopard running on it.Unfortunately one of the software that I use doesn't have yet a Snow Leopard update. So I am thinking maybe I can install older version of Leopard on one of the internal drives (i have 3 additional internal drives), so I can boot my computer from either Leopard or Snow Leopard, depending on needs (i don't want to get rid of Snow Leopard).
I never installed OS X system before, so I am a bit scared.The internal drive is ready, I have the old Leopard on disks, what are the next steps to take?

Running Disk Utility's Repair Disk function from DVD, how long should this take to complete with a 1 TB drive? It's been nearly 24 hours so far. I booted the computer from the DVD, and after verifying the disk was told the disk needed repair.

I have an old Macbook via 2007 and I'm trying to update my operating system (currently OS 10.5.8) to Snow Leopard, but the disk is not reading in the disk drive. And unfortunately, Snow Leopard is only on a DVD, it can't be downloaded.I figure I have 2 choices:
1) take it in and spend $49 to have them do diagnostics and then tell me they probably need to replace the superdrive
2) I could buy an external optical drive. But I would need to know which one would be compatable with my old *** Macbook.

Well in my quest to upgrade my MBP 5,1 I got my memory and a 500 GB Seagate Momentus XT from Newegg. I'm enjoying 4 GB of RAM now. So, I'm debating with myself about what to do. Obviously, a new HDD is a great opportunity to install Snow Leopard and start from a clean slate. Or I was thinking about cloning my current Leopard install to an external HDD with CCC, but I'm having trouble understanding how I would accomplish getting it back. I'm thinking you can do this by booting from the install disc, but I'm not sure. So, if I go the SL route, will I be able to use Migration Assistant and an external enclosure (if anyone could recommend one, that would be great!) for the old boot drive to move my important stuff over?

Can I install 10.6 on the Mac Pro from the Installation DVD that came with the laptop or does Apple require me to buy the software twice?

Some weeks ago I accidentally deleted the app x11 from my iMac (I have the version 10.6.8). Now I am trying to install a game that needs that app. I've tried to download and re-install the x11 from the Apple website, but when I'm installing it, a message shows up saying that "x11 can't be installed. a more recent version of this software is already installed". but that's impossible, since I deleted it! I've been looking through my iMac with the Finder and the app x11 doesn't show up, so it is definitely not in my computer. What can I do to install the x11 in my iMac again? I don't think it's possible that the app still remains in my computer.

I'm trying to install Mac OS X Snow Leopard on to my macbook but I keep getting this error.
"mac os x installation couldn't be completed" I get this message usually within 5 minutes of installation.
My macbook specs are...
Mac OS X Version 10.5.8, 2.16 GHz Intel Core 2 Duo, 1 GB 667 Mhz DDR2 SDRAM
I've already tried repairing the disks. (I repaired my leopard with the snow leopard CD because I couldn't find the leopard CD.
I heard it was fine to do.) I would have tried to verify and repair the partition but the buttons seemed to be grayed out for some reason.
Here is the error log...

Will it install like the OS does on the iPhone, as in the existing data isn't put in a new folder? What exactly happens when you install a new OSX?

After 5 years with 10.3.9 on an iBook, I've bitten the bullet and bought one of the new iMacs. The transfer has gone fairly well, but I'm having trouble moving my address book and keychain data across to the new machine.
They didn't come across using the Migration Assistant: the Snow Leopard Keychain won't accept anything exported from the Panther version. If I export the address book as V-cards from the old system (the only means of export, the new systems asks me whether I really want to import n cards, but after I say yes nothing appears in the bbok.
It's al very frustrating, (and not very Apple-like!) I'm on the verge of doing the whole thing manually, one address and one keychain entry at a time, which seems quite daft.
