Freezing and not booting from CD-ROM

I am the ultimate 'techno-lagging' individual so bear with me! My computer keeps 'sticking' i.e. it freezes for about 10 secs every minute or less. To try to correct this, I ran Norton which told me that I had major problems on the Catalog-B Tree and had to re-boot the computer using the Norton CD-ROM as the StartUp Disk to correct this. So I did.
The problem is that the computer will not re-boot from the CD-ROM, it keeps opening up with the Internal Software. I also tried using the Disk Warrior CD-ROM with the same result. I haven't got with me the original OS X installation disks. I ran Disk Utility which repaired the 'permissions', yet the problem persists.
How on earth can I get the computer to recognise either of the aforementioned CD-ROMs as the Start-Up Disk? Or is this such a mega-problem that I'll have to take the dear machine to the nearest Apple Dealer Hospital?
Help!

Welcome to Apple Discussions.
First of all, get rid of Norton. If you have it installed on your HDD, remove it.
Symantec's Norton Uninstall
Mac OS X: How to remove and recreate an inaccessible keychain
Symantec no longer supports Norton for OS X, and Norton can wreak severe damage to your directories.
The utilities of choice for Mac OS X are:
Apple's Disk Utility
Disk Warrior
Tech Tool Pro
Begin wtih Disk Utility and
Repair Disk
Insert Installer disk and Restart, holding down the "C" key.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
Please do not hesitate to post back should you have further questions.
Good luck.

Not booting from CD ROM

Hi,
I have Sunblade 150. The HDD of system is totally crashed. I want to boot it from CD ROM to do the installation of Solaris 8. But i am not finding the option to boot it from CD ROM. When ever I start the system it tries to boot from network. The HDD of system is blank and unpartioned. How do I boot the system from CDROM .........Can any one help me.......
Regards'
Animesh

Hello Animesh ,
power the system on. Wait a few seconds, then press the keys STOP and A simultaneously. This should get you to the ok-prompt.
When you see the prompt, enter setenv auto-boot? false and setenv diag-switch? false. The first command disables automatic boot from the boot-device (which is either one of the disks or the network). The second command disables diagnostics (the POST Power-On-Selftest is not affected). If no bootable device is found, the system tries to boot from the network (the diag-device).
Then insert the Software 1 CD (the Blade 150 requires Solaris 8 2/02 or newer) and enter boot cdrom to start the installation.
When the installation is finished, on the next power-cycle the system won't boot automatically. Just enter setenv auto-boot? true to re-enable automatic boot. Then enter boot.

Any updates ?

Will not boot from CD ROM - MountCheck Error

Had a system crash. Since then had problem with corrupt system on one drive. Am trying to load OX10.2 on drive. Start installation telling it to launch from disk and reverts to a SCSI drive. Hold down "S" when starting and also launches from SCSI drive.
Sometimes when I try to install OS, it comes back with the following error:
Startup disk was unable to select the install CD as start-up disk. (-1)
Did Disk Firstaid on CD drive and it said:
"MountCheck found minor errors.
Did PRAM ZAP, removed battery and pushed reset button. Unplugged CD, booted on and off. Plugged in CD again, hoping it would find and install correctly. No help.
Have tried launching off of 3 separate CDs (OS8, OS10.2, OS10.3) none launch.
Now what?

Hi, 61319tele -
As far as being able to boot the machine from a hard drive using OS 9 -
• Be sure OS 9 drivers were installed on the drive. If OS 9's Drive Setup was used to format the hard drive, they're installed automatically. However, when using OSX's Disk Utility to format the drive, the installation of OS 9 drivers is an option, one which is not always selected by default. And, be sure the drive was formatted as Mac OS Extended (also called HFS+).
• If the drive is larger than 200GB, it must be partitioned such that the volume OS 9 is on is no larger than 200GB; 190GB is a safe size.
• Be sure the jumpers on the drive are set correctly. Cable Select is not a good choice for your model.
As far as being able to use the optical drive for OS 9 booting -
Does the machine boot to an OSX Install disk?
One way to test an optical drive - disconnect the hard drive, then try booting to the optical drive. All G4s should boot to the optical drive even if no hard drive is available.
Since you have replaced the drive, make sure the drive is jumpered correctly - in order for it to be bootable, it must be jumpered as Master.
By user reports, it appears that some machines will no longer boot to their original pre-OSX CDs after the machine's firmware has been updated. One way to test to see if that is the case is to try using a retail (white label) OS 9.1 or OS 9.2.1 Install CD. It should boot to either of those after the firmware has been updated.
I would question the ability of a copied OS 9 Install CD's ability to boot a machine - it's too easy to get it wrong. In particular, if the source disk is not a valid one for the machine (neither an original Software Install CD nor a retail OS 9 Install CD of adequate version), it won't be able to boot it. Since the copied CD apparently will boot your G3 (what model is that machine?), the source disk may have been one that came with the G3, hence is model-specific to it.

Optical drive trashed and MB Pro will not boot from USB image

Hello,
New here but I have searched and tried all I know to get this MBP working right again. My disk drive is trashed and has been for some time now, this is why I have a bootable version of Snow Leopard on an 8G flash drive. When my MBP began acting funny recently and I went to disk utility to verify permissions and the disk. Both failed = must boot from disk to repair, thus my issue. For some reason by MBP will not boot from the usb image I have used previously??? Pressing C or Option during startup does not work. If I press Option, I only get the harddrive option, C yields nothing and the computer boots normally.
Please!! let me know how / what you would do to resolve this. I don't understand why I have previously been able to boot from this same file on the same drive previously to repair my disk / permissions but cannot do so now. FWIW, I tried placing the file (OSX) on my external HDD to boot from, this did not work either (USB HDD).
Thank you in advance for your input!!

It isn't clear what you mean about your HD being trashed or which disk (HD or USB drive) you are trying to repair, but either way you need to start up from your Snow Leopard installer DVD & instead of installing anything go to the Utilities menu & run Disk Utility from there to repair either or both of the disks.

Macbook Pro will not load OS and will not boot from Install Disk

When I try to turn on my macbook pro it goes to the gray logo screen with the spinning gear however it does not progress from there and then after several minutes it proceeds to restart itself and the same process repeats itself. I have tried to boot into single user mode with success and have run /sbin/fsck -fy and that has returned that the volume appears to be ok. However, when I hit reboot it returns to the same process of the gray screen and spinning gear to black screen which repeats. When I boot into verbose mode it progresses to AppleYukon2: RxRingSize <= 1024, TxRingSize 256, RXMAXLE 1024, TXMAXLE 768, STMAXLE 3328 then it stalls for several minutes and then it shows continuing
synchronizing disks... Killing processes
then it says some other stuff to fast to read.
When I try to boot from the install disk it will not boot from holding the c key it goes through the same aforementioned cycle. When using option to boot I can see the Disk then when I select it the cycle happens again.
Also I have XP installed and I am able to boot into that successfully. Any help would be greatly appreciated.
Not sure if I left anything out
-bryce

Welcome to Apple Discussions.
Do you have multiple Accounts defined on that system? The last time you successfully were running, did you run from the Account with Administrator privileges?
Do you have another computer from which you could boot and connect the Macbook Pro in Target Disk Mode to take a look at the drive from your working machine? Perhaps you can run Disk Utility from the working machine and point to the hard disk on the failing Macbook Pro.

T500 will not boot from bootable CDs/DVDs, but will read and open files on them

System: 2 T500s, both manufactured early April 2009, win XP, ATI Radeon 3650 graphics,4GB RAM, latest Lenovo drivers installed..
Problem:- Our 2 T500s cannot boot from any windows coded recovery CD -except Lenovo's rescue/recovery discs. Some -but not all- Linux code recovery CDs do boot the T500. Every other kind of CD and DVD such as audio and video works fine in windows XP.
Here an example of our 2 T500s' failure to recognise bootable CD/DVD discs. All the files and folders on a Paragon Partition Mgr v8.5 Recovery CD can be viewed in windows explorer and files such as jpg, txt and zip can be opened. This CD will not boot the T500, however, it will boot our other -non-Lenovo- computers. The same applies when the media are DVDs with identical content.
We have tried several different kinds of CD and DVD media to no avail. Burning the media on other computers and using several kinds of burning software does not help, ourT500s refuse to boot from them too.
The problem seems clear enough, on starup our T500s fail to distinguish between windows coded bootable and ordinary CDs/DVDs -unless they are Lenovo recovery/restore discs.
A solution would be gratefully received.

Thank you for your very kind assistance,
Q: "1. Did you apply the DVD firmware fix here?"
A. It was` already installed on our 2 T500s. We have also applied just about every driver update from Lenovo.
Q: "2. Did you try booting from a USB optical drive that you first attached to another system where you could verify that booting from it was possible?"
A. Yes, many times from a USB CD/DVD drive, it failed too. We burned on that drive too, but the T500s will not boot from those CDs either.
Q: "3. In this thread the solution was to use another burning program than Roxio..".
A. We have used the Paragon internal ISO creator/burner, the Roxio burner that was preinstalled wth the T500, BartPE internal ISO/burner ,InfraRecorder and others too. Made ISOs and burned from them, burned CDs directly on the fly etc, all to no avail..
For some reason, our two T500s' CD/DVD drive controllers or some intermediate software act as if the CD's boot sector is not present. Clearly, something (BIOS, software, unstable hardware, or ? ) is blocking the read or write of the data necessary to boot these CDs. Whatever that 'something' is, it has no effect on burning and booting Lenovo recovery CDs.
The bizarre part of all this is that a`Lenovo recovery CD burned on the T500 drive WILL BOOT the T500. A Paragon v8.5 recovery CD or BartPE CD burned in one of our non-Lenovo computers will boot ithat and every other computer we have except our T500s.
PS Thank you for the link to the new version of Roxio, will download and install it.

Not booting from 10.4.8 volumes after upgrade from 10.4.7

I'm sorry to report that my aged G4 450 MHz AGP with 4 internal Hard disk drives no longer boots from any of the 2 volumes upgraded to Mac OS X 10.4.8 as soon as it was started from another volume!
All was working fine as long as 10.4.7 was installed on the 2 232 GB disks connected to the SIIG ATA133 controller. I could boot from any OS on any of the 4 disks, 5 partitions:
internal ATA66 bus:
18 GB disk, 2 partitions: 'IBM_18GB' with OS 9.2.2 and TechTool Pro's 'eDrive' with 10.4.7
71 GB disk, 1 partition 'IBM_71GB' with OS 9.2.2
PCI SIIG ATA133 controller:
232 GB disk, one partition 'I1232GB' with 10.4.7, now upgraded to 10.4.8 and no longer bootable
232 GB disk, one partition 'I2232GB' with 10.4.7, now upgraded to 10.4.8 and no longer bootable
Now I can only boot from the Mac OS 9.2.2 or the eDrive 10.4.7 partitions.
What I did so far: 'I2232GB' was my main OS X startup volume, 'I1232GB' contains a clone of it, plus additional folders like software base and backups.
After upgrading 'I2232GB' to Mac OS X 10.4.8 through Software Update and repairing permissions all was OK as long as the Mac was just shut down or re-started: it always booted up in Mac OS X 10.4.8 from 'I2232GB' without any problems.
The next day I booted from 'I1232GB' to do the same there.
Afterwards I could no longer boot in Mac OS X 10.4.8 from 'I2232GB' nor in in Mac OS X 10.4.8 from 'I1232GB': it just gets to the grey screen with the Apple logo, but the round circle underneath indicating some progress never appears. I left it there for hours: it just hangs.
With the Option key held at startup I could boot from the other partitions with Mac OS 9.2.2 or the eDrive with 10.4.7. None of their Startup Control Panels was able to get me back to 10.2.8!
So I booted from the TechTool Pro 4.5.1 DVD to Optimize both volumes, 'I1232GB' & 'I2232GB', always Files only.
Then I booted from the DiskWorrior 3.0.3 CD to rebuild the directories of both volumes, 'I1232GB' & 'I2232GB'.
Still I can not boot from either 'I1232GB' or 'I2232GB' in Mac OS X 10.2.8!
Downloaded the Mac OS X 10.2.8 Compo Update (for PPC) and installed it onto both 'I1232GB' & 'I2232GB' while booted from the eDrive which I keep on Mac OS X 10.4.7 - no luck either, still I can not boot from either 'I1232GB' or 'I2232GB' in Mac OS X 10.2.8!
Then I backed up the users folder from 'I2232GB' onto 'I1232GB', booted from Mac OS 9.2.2 and used Intech's Hard Disk Speedtools 3.6 to format 'I2232GB', afterwards initialized it with Alsoft's Plus Maximizer Extension for a Block Size of 512 Bytes.
Installed Mac OS X 10.4 from DVD, as well as iLive '06 and upgraded everything to the latest releases with Software Update. All was working fine with all the required reboots until another startup volume was chosen: afterwards again I can no longer boot back into Mac OS X 10.2.8 on the fresch installed 'I2232GB'!
Any help would be appreciated.

I found several typos in above post, wherever it was 10.2.8 it should have read 10.4.8 - I'm very sorry for confusing you, this would not have made sense, but I found no way to edit the existing text therefore I modified the quote of it here.
I do not need Mac OS X 10.2.8 back, but it would be nice to boot back in Mac OS X 10.4.8 from another volume as the current one - which was working fine before with Mac OS X 10.4.7.
Many thanks,

IMac will not boot from any mode except Target Disk

I have an Early 2008 Penryn iMac 24" MB398LL/A running OS X 10.7.4 (see specs below) that will not boot from ANY mode, It also has several strange vertical bars from top to bottom on the screen. They are about 10 px wide, with some pixels empty and looks a bit like a barcode if you squint at it.
I have tried Safe Boot, Force Boot, DVD Boot, FireWire/USB Boot, and it always gets to the same point. It gets to the apple screen with the spinning gear and then after about 8 seconds it freezes. The only way it works at all is in Target Disk Mode. It pops right up on my Macbook Pro and I was able to grab all my info!
I have run Disc Utilities and Tech Tool on it many times from my MBP and it passes every test.
I reformatted the HD and installed 10.7 again, it still freezes up at the same point.
I have tried using Single User mode and every time have had to run /sbin/fsck -fy twice because it always says the disk is ok but it was modified on the first pass.
I thought maybe it had a bad video card or logic board but and I ran the Apple Hardware Test on many occasions and it always passes. Recently I was told about Loop Mode and just completed running the AHT for just over 30 hours without any errors at all.
UPDATE...
Strange Part… I tried installing Mountain Lion in Target Disk Mode and everything went smoothly. When it restarted on its own the lines on the screen were gone for the moment, but the Mac still freezes up on the spinning gear and immediately restarts on its own. I have run every thing listed above on it and still nothing. Sometimes the lines reappear then in two more starts they are gone.
I did manage to have it start one time got a copy of the the error report (its at the bottom too) The Mac ran for at least 30 minutes with no problems, then the screen went crazy a few seconds and it became unresponsive. The mouse moved but that was all it could do. Now my iMac continually restarts itself, I don't have any more ideas, HELP!

PowerPC G5 will not boot (from CD, single-user, verbose...) - is it dead?

I had posted this in the OSX forum but had a suggestion to post here as well - any suggestions would be greatly appreciated!
My PowerPC G5 (10.4.11) will not boot. It gets to the grey Apple screen, and then freezes there, no progress dial, and the fan starts racing after a couple of minutes sitting there. Here is what I have tried so far and the results:
-Will not boot normally - freezes at grey screen
-Will not boot from CD (DiskWarrior, 10.4 Install disc OR 10.3 Install disc - which came with the G5, each time it freezes at grey screen
-Will not boot in safe mode - freezes at grey screen
-Will not get into single-user mode, freezes at "DART-enabled"
-Will not get into verbose mode, freezes at "DART-enabled"
-Holding option when starting up allows me to select a drive (hard drive or CD), but then freezes at grey screen when attempting to boot from either drive
-Option-Command-Shift-Delete does nothing when starting up, again freezes at grey screen
-Option-Command-P-R does not work - well, maybe it deletes PRAM, but it never even gets to the grey screen, freezes with a blank (black) screen, so that can't be right
-I CAN get into open firmware & eject cd, cannot boot up from there - it freezes at the grey screen with a circle w/a line through it
-Attempted to reset NVRAM from Open Firmware, "reset-nvram" and "set-defaults" both were ok, then it froze after "reset-all"
I have tried everything I could think of and everything I can find - Does anyone have any possible suggestions or ideas for what I can do?
I had a couple suggestions that it could be RAM, so I'm going to try to run Apple Hardware Test, though if I can't boot from a CD, that will make that very difficult. Any thoughts?

Hi svman8-
Did you also reset the SMU?
One thing known to cure various ills is to replace the battery.
This may be a helpful link:

Sunblade 1000 will boot from CD-ROM or DVD-ROM

I have Sunblade 1000 with a pre-installed Solaris 8 OS. I originally purchased the workstation without a CD-ROM. I bought an old Sun 411 CD-ROM. After installing the 411 CD-ROM, I entered "boot cdrom". Somehow it will not boot from the CD-ROM drive. When I do a "probe-scsi-all" I will often get "fatal scsi errors", but sometimes the SCSI info will be displayed, bizzare. When I type the explicit or long device name with the boot command, it still will not boot. After looking for solution in the Internet and exhausting a few UNIX friends from my questions, I called Sun. According to Sun, the only compatible CD-ROM for the Sunblade 1000 is the DVD-ROM, which is OEM by Sun,and usually ships with this workstation.
After, getting over the shock that Sun sold the Sunblade 1000 without providing backward compatibility, and suffering the humiliation of spending much need company resources for a potentially useless CD-ROM, we broke down and bought the DVD-ROM.
After spending $500 dollars for the DVD-ROM, the Sunblade still cannot boot from the DVD-ROM. If I boot from the disk, and after the system comes up, the DVD-ROM shows that it is mounted, I can browse it's content, etc.
I currently have the Solaris Installation CD in DVD-ROM drive. I also tried booting off the Solaris 2.51, and 2.7 CDs. Here are some info that comes back when I entered the various commands:

I'm quoting from an old usenet article from Tony Walton
(@...sun.com)
http://groups.google.com/groups?q=solaris+probe-scsi-all+reset+auto-boot&hl=en&lr=&safe=off&site=groups
�
You should only run probe-scsi after the hardware has reset
but before it's initialized to start running Solaris (you
might get away with stopping then running probe-scsi early
in the boot sequence, but that's only a matter of luck,
really).
The recommended sequence is to disable autobooting if it's
set (so the machine won't boot itself automatically after a
PROM reset), then reset the hardware, then probe-scsi, then
re-enable auto-booting (if it was enabled in the first
place).
So, go to the ok prompt, then
setenv auto-boot? false
reset-all
probe-scsi (or probe-scsi-all)
setenv auto-boot? true
reset-all

How to boot from CD-Rom on 520CDT with no OS on hard drive

Hi
I formatted the drive on this Tecra 520CDT laptop (old I know but I have a use for it), only to discover that it does not seem to want to boot from the CD-Rom drive. I no longer have the interchangeable floppy drive. Any suggestions as to how I could force it to boot from CD-Rom (I have changed boot order in Bios) Windows disks or something else?
Until I can do so, I cannot reinstall an OS.
Alternatively, will any old external floppy drive work, and if so which port? will it boot from parallel port?
Thanks
Jonathan

Hi,
on these "Oldies" you have to create a boot floppy disk with the CD Driver.
Then you must connect the CD and Floppy Drives, have to boot this Floppy disk and C: prompt will be available!
Then when the CD ROM driver was loaded you can start the CD.
It can be that you need the original Toshiba Drives!

IMac not booting from HD, cannot repair disc in Disk Utility

First the problem:
I've had the imac G5 for nearly two years and its been running without a problem, now it suddenly wouldn't start up. Firstly I get two or three grey screens in succession looking as if being drawn from top to bottom very quickly, then the apple logo and timer, after a minute or so the fans start up to full power and it stays that way.
What I've tried:
Reading around discussions I tried rebooting from DVD installer and using disk utility. Result: error message: The underlying task reported failure on exit. 1 volume could not be repaired because of an error.
Because I want to sell the imac I had backed up all of my important data so I zero-wrote the hard drive in preferrence to buying a third party repair package. Reinstalled from DVD. Shut down and restarted. Everything worked except those banding grey screens appeared that were never there before. Something looks wrong. Then when i tried to reinstall microsoft office (as a test) the OS seemed to freeze and I had to shut it down again. Now it won't boot up as before. This looks like a very serious problem.
I hesitate to buy tech tool pro in case that doesn't solve it either.
Can't think if I did something to cause this. All I've been doing is transferring some data via ethernet to a newer mac. There was also a Lacie firewire drive linked to both computers as i was backing up stuff. One night I shut the iMac down and the next day it started with this problem.
Well... any educated suggestions would be most welcome,
thanks.
By the way, the memory in the mac was purchsed from a third party and installed ages ago by myself. Never been a problem with it and have been running Final Cut Studio no trouble.
iMac G5 2GHz Mac OS X (10.4.7) RAM 2GB

Long story short, I had the same problem last week, just after installing the latest software updates. I went through all the resets and disk utility verification (multiple times with phone support -- Apple Care), then took it to the local Apple store b/c nothing worked. They couldn't figure it out either and recommended that I try to backup my data on my bootable external drive before they started messing with my hard drive, since Apple stopped providing this service. I brought it home, could not boot from my external drive, so booted from the disk again, just for kicks I ran the same verification process (this was the 3rd or 4th time). This time something happened but it still failed. So I ran it three more times (each time something new happened and then it failed, until the third time when everything worked. The only problem now is that I seem to have lost all sound???? I did immediately make a duplicate of the Imac hard drive. Any thoughts on how to get my sound back? hope this helps....

Not Booting from DVD Solaris 10

Hi,
I am trying to install Solaris 10 on Sun 420R Sparc. I am trying to install it with DVD. But when I try to install it by using the command boot cdrom. I get the following error.

I have checked the DVD. I ran probe-scsi-all and it looks good.

Can anyone help me with this?

The 420R first shipped in November 1999.
Initially, they all had CDROM drives and not DVD readers.
You might also get that same error
if you are inserting a DVD disk into a CD drive.
Next, the 390-0025 DVD drives had problems booting
from any DVD media with more than (I vaguely recall)
something such as 3GB of data on it.
They could read from them,
just not boot from them.
That was a peculiarity of the drive.
Recent releases of Solaris 10 fill those DVD disks.
Try your installation with CD media instead of DVD's.

Touchsmart 610 will not boot from CD drive or USB device.

Hi all
I have a TouchSmart 610 and I performed a standard restart but it would not boot. I tried the various options in restart recovery to no avail.
I made a win 7 recovery disk on another win 7 64 bit machine to try and repair the Windows os but I cannot get the PC to boot from the CD drive.
I have altered the boot order in BIOS so that CD is first. But when I try to boot up it goes to the windows recovery screen again.
I have an "ultimate boot" disc and tried to boot from that but same problem.
If I look at Bot order in BIOS it still says CD is first.
Anyone got any iddeas?
Thanks in advance.

Hello Grasper,
Welcome to the HP Forums.
I understand that you're having an issue with the computer booting from CD Rom. I will do what I can to help with this.
Check the BIOS and make sure "legacy devices" is enabled.
You can also try and manually boot to the CD ROM. On start up if you press F*(F8/ F9/ F11/ or ESC. it varies per computer) It will bring up a menu with the devices you can boot from. If the disk drive is listed select it and see what happens.
If nothing happens it could be an issue with the CD ROM itself. You could try another drive in that case. If its still not working at this point, then it could mean an issue with the motherboard itself.
I hope this was able to help you out. Thank you for posting on the HP Forums.

MacBook (not unibody) will not boot from Boot Camp USB Key

Hello
I have a MacBook Pro 2007 (17", 2.4GHz, 4GB RAM and SSD) with a defect SuperDrive, and I want to install Windows using an USB key instead. But the computer will not boot from the USB Key, even though the USB key works on my MacBook Retina. Also I was able to install Mountain Lion using USB Key, on the MBP 2007.
Here is a bit more details:
I've installed Mountaion Lion from the same USB Key (so boot from USB works).
I've installed a Windows 7 Boot Camp using the SuperDrive before (when it was not defected)
I've partitioned the harddisk using the Boot Camp assistant (this requires a Windows DVD in the SuperDriver... however it worked just enught to be able to have OS X recognize the Windows DVD, and create the Boot Camp partition). So far so good. Installing from the SuperDriver howerver does not work.
I've created an Windows USB Key using my MacBook retina. Because the Retina does not have a DVD, the Boot Camp assistant offers the creation of a bootable Windows USB Key from an Windows ISO file. I've used this USB key to install Windows on my MacBook retina.
When I try to boot my MacBook 2007 with this Boot Camp USB Key, it shows an "EFI Boot" option (with a orange USB logo) in the MacBook boot menu. When I select this nothing happpens. The mouse freezes, and the computer never boots.
Questions:
Shouldn't I be able to boot from an EFI USB Key on this MacBook 2007, when I'm able to install Mountain Lion using a USB Key?
When I installed BootCamp using the SuperDrive, I had to do som "magic" to make it bootable. Like this: http://www.logicalvue.com/2009/10/installing-window-7-x64-on-a-macbook-pro-using -bootcamp. I tried doing the "oscdimg -n -m -bc:\efi-dvd\boot\etfsboot.com c:\efi-dvd c:\efi-iso\win7x64.iso" trick and create a EFI bootable ISO and created the from this USB key using http://unetbootin.sourceforge.net/. Same result... the USB key shows up in the boot menu, but nothing happens when I select it (except the mouse freezes).
Any suggestions? Right now it feels like I have a bricked computer, because my kids needs Windows to run their games.

Thanks... I just tried rEFIt... and it almost worked.
After installing rEFIt I got several different boot options:
Bootmgr.EFI - This failed quick with a "unsupported" message
Bootx64.EFI - This actually started the Windows installation with "Loading files.............". But after a few minutes when all files was loaded, the screen went black. I tried ataching an external screen, but the screen was still black.
Boot from "Bootcamp" drive... as this drive is empty nothing happend.
Boot from "USB Key"... I'm not sure how this is different from the first 2 options... but nothing happend. I belive this is what happens if I try selecting the USB key from the build in boot manager.
Ofcause, whan I saw the "Loading files......" I thought I solved the problem, but as you can tell, I'm still stucked.
Actually... I tried with both Windows 7 64 bit, Windows 8 64 bit and Windows 8 32 bit. Only Windows 8 64 bit, got me to the "Loading files.....". This was created with the Retina Boot Camp assistant.
I also tried my own home made Windows 7 and Windows 8 ISO (created with this link: http://www.logicalvue.com/2009/10/installing-window-7-x64-on-a-macbook-pro-using -bootcamp).
I guess my problem is another now. I'll continue my hunt... but I don't have more time right now. So I've installed Parallels and Windows 8 for my kids. Not optimal, but at least the can play their games.
