I have a MBP with Windows on a separate partition. Normally, the computer boots to Windows by default; pressing the Option key at startup gives me the OS options. Typical, right?
But suddenly I can't get OS X to boot. Instead I get a blank, lit screen, but the hard drive spins, the KB works (tested it in Windows), the fan runs, the optical drive tries mightily -- but no OS X. After about 5 minutes, Windows finally boots. Even that kind of wait is wrong.
I tried booting with Install disks 1 and 2, pressing all combinations of keys: Cmd/Opt/Shift/Delete; the C key; the trackpad button -- I'm just trying to get the disk to reinstall everything from scratch, and hoping that would cure. But I can't even boot from disk. Also, Safe Mode won't kick in.
Any suggestions? Is OS X lost forever? This is weird. All I can think of now is putting in a new HD.

sorry man but i cant help here.
*waits for sam and all his bootcamp smartness* -
*tells sam on the random thread to get over here*
when did it happen did you install some thing before it?
SAMS ANSWER:
-
Who me? I don't know either, sorry . Do you happen to have an external hard drive that is a backup of your entire OS X?
-
So you already tried a PRAM Reset and SMC Reset?
Sounds like a hardware problem, I really have no clue though. Contact Apple. -
Can you be a little more specific? What exactly happens when you hold down Option at boot-up? Does the Windows/Macintosh selection screen even appear?
In addition to resetting the PRAM and the SMC, you might also try booting into Windows, since you can do that. Boot Camp manager's startup manager in Windows isn't simply for "Boot Camp" only - you can insert startup disks and tell it to manually boot off those disks as well, as well as run the partition in Targeted Disk Mode. There are also options to restart the system directly to OSX in the Boot Camp manager as well. -
dn, I just found this, I am not sure if it the same issue as you have, but have a look just in case--here is the link to the site, and here is an excerpt:
-
-
Is there a program that will allow windows to read the mac formated section? If so Get the files from there and just re-install both of them with a clean install from the Apple cd's.
-
MacDrive will let you read HFS+ partitions. It costs money, but there's a 5-day free trial, which is probably long enough for you to recover your data if necessary.
-
I can't find anything anywhere in Windows re. Boot Camp, startup manager (I looked all through msconfig, etc.) -- and what is Targeted Disk Mode?
And Passive, this being Boot Camp, Windows has no knowledge of the Mac partition (correct me if I'm wrong), so I can't figure a way to read it.
It's not that I have so much data to retrieve -- most files are on a flash drive. I just want OS X back! I will give MacDrive a try.
Does anyone else think the HD might just be shot? -
Boot camp startup manager should be in the Control Panel, if it's not on your taskbar (the icons on the lower right hand corner of the screen usually).
One thing you might try if you really can't find Boot Camp Manager is to reinstall the Boot Camp 1.4 drivers (this is assuming you already burned them onto a CD, since you'd need to access OSX to get them). -
Found it. I told the computer to automatically boot up OS X, but no go. It went back to Windows by default. I'm taking a break!

looks like its not exactly damaged. It just doesn't want to boot.
First, try using a linux live-cd to recover most important files. I recommend knoppix. its really simple to use. Just drag and drop files you need.
EDIT-
Oh well... by the way if you wanna try to repair your disk partition table you can also try using "parted" in linux. Its a bit complex but it supports mac disks. If you try to do this, i would suggest backup windows too cause you can end up deleting it too lol.
Parted is a comand line tool so its a bit difficult to use at first. The "rescue" command within parted is really good. http://www.gnu.org/software/parted/manual/html_mono/parted.html#SEC24
just use rescue start: 0 end: sizeinMB (approx, try using a bit more)
And i forgot to mention, this knoppix and parted is free software under GPL, you can download it free from http://www.knoppix.org/ the 700 MB version will work though if you wanna try linux the 4 gigs version has A LOT... A LOT of software
Help! Lost my whole OS X partition.
