OS X :: Snow Leopard Installed From External Hard Drive Won't Boot?
Feb 16, 2010
I have no id� whats wrong, I want to install Snow Leopard(from the external) on my Core2duo Macbook pro, which is running Leopard at the moment.
I have a Snow Leopard image, and I have used Disc utility to partition the external hard drive (GUID), and I assume the partition and install went well on the external, because in Disc start the external appears as OSX 10.6.
Then the problem: The macbook wont boot from the newly made external it just gives me this sign (of course without the colours).
I have tried to start the macbook normal, and with the option key held down were the external pops up.
I have also tried to chose the external in disc start and reboot with no luck.
I have tried to start the Snow Leopard install(external) within Leopard where the install start fine, but when it reboots and wants to continue the install, the sign appears.
The external harddrive is a 5400rpm 40gb 2,5" which is only powered by the usb port maybe thats the problem?

I've got an iMac Intel Core 2 Duo running Tiger 10.4.11.I've successfully installed Snow Leopard 10.6.3 onto an external drive (or so the screen said).My mac recognizes the external drive as a start-up disk and allows me to select it as such. But upon restart, machine comes up in Tiger.My external drive is brand new, OWC Mercury Elite AL Pro using a fire-wire connection. After installation but two failed attempts at start-up, I ran first aid on the external and no repairs were necessary. Using System Prefs I selected the external as my start-up disk, hit Re-start, but machine still restarts from Tiger
The only other piece of information that may be vital, that I can think of, is that I misunderstood the "Mac readiness" of the drive when I took it out of the box. I first erased it (unnecessarily). Then I discovered this mistake, and made a point to re-format it using the GUID partition setting. Computer claimed that installation was successful upon installing Snow Leopard.But now, machine will not start up in Snow Leopard.

After many unsuccessful rounds of burning to DL DVDs and flash drives, I settled on making my iPod bootable and running it from there.So I'm excited and running my startup disk on my MBP as the iPod and I've connected my MBP to my iMac G5 PowerPC through firewire and enabled target mode. After booting into the iPod, it gave me the option to install to the new hard drive from the iMac G5 (which is currently connected to my MBP). I installed it through my MBP, and assumed it had installed to my G5.

My OSX partition shows up fine in my Bootcamped Windows 7 x64, and I can read/write to it fine. My external, a Western Digital 1tb drive formated HFS+, is connected thru firewire, and it doesn't seem to mount or show up at all.

On their website FAT32 download dosnt work! I have tried disk utility with no luck. What am I missing?

This is a major issue for me, as I feel like I'm going to end up damaging my hard drive.
I am downloading a legal torrent to my external hard drive, however when I quit Transmission and try to eject my external drive, nothing happens. Snow Leopard doesn't even say it is in use like it is meant to. It just does nothing to eject the drive.
So I end up having to yank the USB plug out.
What gives? It ejects normally as long as I don't download to it.

I have installed my hard drive from a previous but terminally I'll iMac that was running Snow Leopard into a Sata to USBÂ enclosure. This is displaying on the desktop of my new iMac running Lion as an external Hard drive,also system preferences sees it as a start up source.My question is , is it safe to restart into Snow leopard without causing a kernel panic and if it does boot will it be fast enough to use as it as a USB drive.

I went to make a copy of an important drive and accidentally re-formatted it (re-formatted mac journaled, originally mac journaled). The drive contained a bunch of important disk image files which I need to retrieve whole. I'm fairly confident that the files are still there and only the table information got overwritten, as the re-format took about 30 seconds. None of the recovery software I've seen however, can retrieve .dmg files, or such large files (these are up to 32 gb each in size).how I can retrieve these disk image files?Â

I have a HITACHI touro desk 3TB external hard dive connected to my iMac OS X version 10.6.8 Every time i start up the system it stays on a grey screen until I unplug the usb of the external hard drive then the system boots up normally. I have tried connecting different usb cables, plug in to different usb ports, and nothing works. I have other external hard drives and they don't give me any problems. is a pain plugging and unplugging the usb cable. Â

Running a 2010 MBP Core i5 2.4GHz. I had Windows 7 originally installed. Gave me wireless problems and I gave up. Erased the partition. Installed Windows XP and everything was fine.
I got a new copy of W7 Professional x64. I installed it "over" the existing XP, though it erased the partition anyways (I don't care about that).The new 7 install has been giving me the same wireless problems. I downloaded and installed the Broadcom driver. Gave me a BSOD and restarted the computer. Now I have a BSOD on start up, too. On the OSX side of things, it no longer shows any Boot Camp hard drive. It doesn't recognize it at all. Though when I hold the option key on boot, it still shows the Windows install.
1. How do I fix the BSOD problem? (All caused by installing the driver)
2. Where the heck is the Boot Camp hard drive/partition?

Have my iMac since March and absolutely no problem. Installed Snow Leopard this weekend and worked just perfect UNTIL I turned the machine off. The next day restarted my computer and now takes about 2 minutes to boot up/then when screen comes up it is frozen for about another 2-3 minutes before can start using it. So basically, takes about 5 minutes from start up to being able to use my iMac. Spent an hour on phone with Apple on Monday night--they really tried--but couldn't fix it and now want me to bring to local Apple authorize dealer to work on it. Called them and they think it is the hard drive going out. But just doesn't make sense---worked just fine until I loaded 10.6 and then turned off machine. Before I bring it in and have them open it up and fool with the internal hard drive---DOES ANYONE HAVE ANY IDEA'S WHAT IS HOLDING UP THE STARTUP.

My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment. I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine Backups? It seems to me I would have to have two partitions for the external drive, one for the system, and one for Time Machine. But is there any way to add a partition without erasing the existing one with Time Machine only on it? Â

Sorry if I am in the wrong forum, as you can guess im a newbie at the forum - not at computers though (6 years experience.. )
So I have a 1TB WD Hard drive USB and I copied the Leopard Disk image and restored it onto it in a 500GB partition.
I have tried to boot it up normally by holding down Alt on start up but the drive doesn't come up. Ok.
I have tried going into the Start up Disk, it comes up and when I click on it and click restart it doesn't restart, it just does that Mac Beep thing.
I have recently just tried to boot it up manually using the Open Firmware technique. It doesn't work.
I have a PPC Mac and I know that they can't normally boot up USB Drives but the other users which I read on the thread how to boot up by the Firmware technique said they're PPC and it worked.
I just wanted to format my computer, My leopard disk is gone now but I got it copied JUST IN TIME to my Hard drive.
I formatted my computer and now i'm stuck on Tiger.

I want to make a bootable clone of my iMac (PowerPC G5 running OS 10.5.8) and also backup my MacBook Pro onto an external USB hard drive so that I can restore from the external hard drive if my iMac dies (which is beginning to have startup problems).
I was planning to create 3 partitions - one for iMac's data which I'll continue to backup using TimeMachine, one for my MacBook Pro's data and one partition as a bootable clone of my iMac.
My question is.... if my iMac dies, how do I use the external hard drive to boot up from? Do I need Carbon Copy Cloner or will I be able to boot up from the external hard drive and access Apple's Disk Utility?

My imac G5 isight's hard drive is dead. I would like to install OS X on an external hard drive and just use that as the hard drive for this machine. My questions are:
Can I boot from an external hard drive via USB and just run everything off the external hard drive? If so, how should I format the external hard drive so that it can be selected and written to when I boot from the install cd? The external hard drive I would like to use is a 75 gig Acom. I've tried booting from the install cd, and it either won't even find the external hard drive, or, when it does, it says it can't write to that external hard drive.

I have an Intel iMac with with Snow Leopard and Windows 7 on separate partitions. Recently I have acquired an external USB hard drive. I formatted it with Ext4, and installed Linux Mint to it.
The installation went smoothly, but I can't seem to boot from the USB drive anymore. Holding down Option on start-up only gives me two choices: Mac OS X and Windows. The drive isn't recognized in either operating systems anymore: on Snow Leopard I get "The disk you inserted was not readable by this computer" and on Windows, it doesn't even show up in My Computer.
