Boot in safe mode with rEFIt + how to recover from dmg on network?

While trying to fix the blank screen problem, I had to force shutdown, and now OSX doesn't boot anymore; Starting with Install DVD, DiskUtility says "Invalid Number of Thread Records", so it seems I'm screwed.
1. I would like to try Safe Boot first, but it seems rEFIt won't let me?
- Holding the Shift button at startup has no effect, I just get the rEFIt menu and OSX starts to boot normally (well it hangs and eats cpu, but I don't see any sign that it's Safe Booting).
- Selecting "Restart in OSX" in the BootCamp Control Panel under OSX and hitting Shift doesn't work (just starts rEFIt)
- Starting up and holding Alt shows BootCamp menu, but that has rEFIt and Windows as items, so Shift doesn't work.
Is there any way to get the thing to Safe Boot?
2. Using DiskUtility, I made a dmg of the entire OSX partition. The dmg is on windows pc, shared through ExtremeIP. Migration assistant doesn't let me pick it, what's the fastest way to restore all my users, settings and applications now?
Thanks in advance!

Cannot boot into Safe Mode with Networking - Windows 8.1 Update

I'm trying to boot into safe mode with networking. I can successfully boot into Safe Mode, but my Network Access is always disabled.
I've tried msconfig / Click on Restart / Restart Now from the Update and Recovery menu in 'Change PC Settings'. They all eventually get me to the Same boot options menu which says ... F4 for Safe mode, F5 for Safe mode with Networking etc.. I
select the F5 Safe mode with Networking and it re-boots into Safe mode but I have no network access.
I'm connecting to my home ADSL, no proxy required. If I boot normally I have network & internet access, but in 'F5 Safe mode with Networking' my networking is disabled.
Windows 8.1 Pro x64

I can see that I am actually connected to my router, but the network icon still shows as disconnected.
What about the Network list via the Settings charm (Win-I)? Last week I was having problems with that one after long sleeps. Later I realized that although I could see the icon in the Settings charm (as normal) when I clicked on it, it still
showed the same icon as I was expecting; the difference is that it didn't show "Connected"; so, clicking on the icon proved that it was offering a Connect button and clicking that finally got me connected. Meanwhile the troubleshooters were misleading
at best and destructive at worst, suggesting I power things off, etc. I don't know if there was a fix for this specific symptom or whether I just tried a different path but yesterday instead of trying the above procedure I tried to see what the Network
troubleshooter associated with IE's "unable to connect" page would do; amazingly it identified the problem precisely. That connection had somehow acquired a connect manually attribute. The troubleshooter offered to fix that problem for me
and I accepted. Since then, no more problem.

Unable to boot into safe mode with FileVault 2 enabled

I was trying to boot into safe mode earlier to try and fix a few things. It looks like I can't and I suspect it is because of FV2.
When the system starts I press shift after the tone, but then I have to release shift and enter the password and then Lion will only boot into normal mode.
I've also tried with sudo nvram boot-args="-x" from the terminal, but while it seesm that this way Lion starts to boot into safe mode, after a while it just restarts as if something crashed etc and then again, I have to enter the password for FV and all again as in a loop, i.e. Lion won't even start this way.
So I went into the recovery mode and I could make Lion start again at least in normale mode with sudo nvram boot-args="".
Any idea of what could be preventing Lion from entering safe mode?
Thanks in advance

The symptom may be unrelated to FileVault 2. I encountered the symptom with FileVault 2 disabled and with backward conversion (decryption) complete.
Apple reference for my bug report: 152162960. If the symptoms on your Mac compare to those on mine: progress may seem to cease during safe fsck.
Vito, as you are comfortable with the nvram command, please try the following:
sudo nvram boot-args="-v -x"
Restart the computer and note the last verbose lines that appear before you sense that progress has ceased. Then please add a note of those lines to this topic.

Is there a difference between any of the Firefox settings in a normal boot as opposed to a boot in safe mode with networking?

I am trying to isolate an issue where I cannot load one particular web page - my local newspaper. The page heading comes up but none of the articles.
In a normal Boot this happens - if I start in Safe Mode with Networking the page is normal and loads correctly.
I was wondering if any part of Firefox is disabled during a Safe Mode boot which could be causing this issue. The website is
http://www.blackpoolgazette.co.uk/news/local
O/S Vista Home SP2. Firefox 3.6.17. Kaspersky AV but for this exercise has been completely disabled

Thanks Luis.
The only difference is the subscriptiion price for students and teachers.

MacBook Pro only boots in safe mode with pink vertical stripes across screen.

So on Friday night I was using Chrome on my MacBook Pro, when all of a sudden little squares of light flashed randomly across the whole screen and everything but the mouse froze. I thought that was weird, so after a few minutes I forced my computer to shutdown. I waited a little and then turned it back on, and opened Chrome again. The same thing happened again, so I forced shut down, backed up Time Machine and ran a virus scan. Nothing came up, so I put it to sleep and and went to bed. Then Saturday morning I went to open my laptop and it was off, which was weird, so I went to turn it on. After the apple logo and spinning gear went away, it booted to a light blue screen and stayed there. Again I waited and nothing happened, so I held the power button down until it turned off. I tried again but the same thing happened, so I booted in Safe Mode.
This time there were inch long vertical bars of horizontal lines, kind of confusing but here are two pictures I took of the screen that hopefully help. http://imgur.com/oj2WbZL and http://imgur.com/O1hwJ1B . When it finally loaded I had another issue, I had 6 pink vertical bars across the screen and a box of pink horizontal stripes around my pointer, http://imgur.com/BJBzu74 . I performed an extended Apple Hardware Test and after 17 minutes it found no issues, and as it performed the test the lines got whiter and made the screen harder to see http://imgur.com/XahBD3s .
I got my laptop June 2011, so it's not that old. I just want to know what this problem could be. I don't know if it's the connection from the screen to the computer, the hard drive, the logic board or something else. I'm really worried that it's something major, so any help is greatly appreciated.
Thank you in advance!

This is a GPU problem. It's normal that you see that the problem is random, but the fact that your Mac is only starting up in safe mode indicates that your Mac can only start up if the VGA driver is used. Moreover, if you open Console, you should start seeing "GPU Debug Info Start", which indicates a GPU failure.
As you have a backup, take the MacBook to an Apple Store or reseller. In the case of the MacBook Pro, the GPU is soldered onto the logic board, so the whole logic board has to be replaced, being a very expensive repair.

HP 210 mini, no "F" keys? How to boot in Safe Mode

Hi, new here so bare with me, hope I'm in the right forum. My mini has no "F" keys at the top of the keyboard, and I need to boot in Safe Mode as I have a virus "win 7 antispyware" that has taken over my whole pc. Can't access programs or internet. I've found a hopeful fix online but need to boot in Safe Mode with networking, in order to download Malwarebytes to get rid of this!
Can anyone here help me please?
Thank you!

All HP mini 210 keyboards are similar, F keys are printed on the top row of keys, upper left portion of the key.

Lenovo has different F8 screen, can't get to safe mode with command prompt - account locked out

Thinkpad W500, Win7Pro. Can't login: "the referenced account is currently locked out and may not be logged on to". I need to boot to safe mode with command prompt to enable the Administrator account (disabled by default) with a "net user administrator /active:yes" command, but Lenova has their own recovery and interfaces which are preventing me from accessing with normal windows techniques. I either need to be able to get a command prompt on the true C: drive, or reset this lockout situation, and fast... Waiting more than 180 minutes did not work, and using system restore is not an option-key software patches and additions make this very unattractive, and I know how to do that.
Optional Information:
Computer OS: Windows 7
Browser: IE
Already Tried:
-ThinkVantage button (reg and advanced views) -a boot disk for pwd reset program (I know password, but I am locked out - didn't help) -F8, Repair options and all safe modes -NOT system restore, as we are trying to not undo months of software revisions - we just need to login!

If we take the error messages seriously, then probably the first thing that you would have to do would be to replace the malformed library:
/System/Library/Frameworks/Security.framework/Versions/A/Security
If you have another computer with the same operating system, you could connect via target disk mode and copy over the good library to replace the bad one. I don't know if this library is different between 10.2.6 and 10.2.8. If the library were fixed, that might solve your other problems and it might not. There is no way for us to know.
Alternatively, you could do an archive and install.

First MBP Grey Screen/Boot Problems/Only boots in Safe Mode

Hi everyone,
I've spent the last few days researching previous troubleshoots and threads on the subject, but haven't had much luck unfortunately.
This is a 2011 MBP, 2.2 GHz, 4 gb RAM, 15 inch. As a preface, I use(d) an external monitor via my MBP's mini-display port, and at some points, the monitor (both) would become distorted, vertical lines running down, and then both would freeze, so I immediately thought my GPU was going. Then after a few restarts after the problem occurred a few times, I got the infamous boot issue: the grey screen (after viewing the spinning logo), so to the forums and research it was.
Now, my MBP will boot in safe mode with no issues. Getting it to boot off of a disc with the "C" option works about 50/50, but I usually end up being able to get to it.
This is what I've attempted thus far from everything I've read:
Repaired Disk: repaired
Repaired Permissions: repaired (both of which I did in safe-mode AND from disc-booting, if that helps)
Reset SMC
Reset PRAM
Reinstalled factory RAM (2 x 2 gbs) ((I had a 2 gb stick and an 8 gb stick) Status of RAM via Profiler: OK
Removed peripheral devices to give that a shot with no luck
Reinstalled OS X (Snow Leopard, by the way, from disc)
Performed both abridged AND extended Apple Hardware Test: No problems found (which is what took me away from Logic Board or GPU issues..)
Used Time Machine backups to restore from previous working date (I regularly backed up my MBP) and have two seperate external drives with backups, though no clones.
Reformatted my entire 750 gb HD, last night, reinstalled the OS X, did not try and restore from Time Machine (as I know I could do that at a later date) and following completion of the OS X install and upon the "restart" requested of me, my MBP had a dark blue freeze, so I cold booted to the same problem of the grey screen, which is where I'm at now.
Summary:
Can Safe Boot with no issues. Reformatted drive. Reinstalled OS X (10.6.7, software update to 10.6.8). Operating with original RAM, went through trouble shoot procedures.
From what I've read, a lot of people have said to replace the MBP Hard Drive cable (SATA) cable, which I have ordered per my model, so I'm waiting on that.
Is there anything else I can do, or try in the meantime? I'd like to know peoples' thoughts on if my HD has failed (thought DU says it's fine) and the fact I can boot in safe mode, and whether a hard drive cable replacement is a probable fix.
This MBP was purchased NEW in June of 2011 and has been well maintained.
Thanks for any thoughts, suggestions, critiques,...anything.

Can't boot in safe mode - RAID startup disk

hi ..
my macpro has a mirrored RAID as a startup disk (using HD bay 1 & 2) ... i am trying to boot into safe mode but this does not work at all, even when holding down the shift key it starts up in normal user mode.
Is there a way to do this ? is it maybe possible to boot into safe mode with a terminal command ? or any other way ?
thx for any help with this ...

Hallo
This topic is quite old, but I face exactly the same issue.
My MacPro tries to boot in safe mode, but restarts and boots in normal mode afterwards.
There are messages in system.log that indicate to me that the kernel exensions on the boot helper volumes are different from the ones on the main partition:

Dec 19 21:06:17 localhost kextd[11]: in-memory mkext doesn't match on-disk mkext; non-boot kexts won't be loaded
I tried:
sudo kextcache -v 6 -f -u /
Which updates the kernel extensions on the boot helper volume,
but it does not work.
As for the firware updates, I could still install those booting from external FW disk.

How to recover from forcing a reboot in safemode without network connections

hi,
I have a hp datavault x510, running windows home server. i wanted to remove a antivirus program which could only be completed when you rebooted in safe mode and deleted it. i forced the datavault to reboot into safemode however i didn't choose the option that says boot into safe mode with network connections, instead i choose without network connection.
since the datavault works through my router i of course need a network connection to access it. i tried to see if the it had a vga/dvi/hdmi connection so i could hook up a monitor to it but is doens't.
is there a way to reset the box to get it out of the forced safemode boot without network connection?

How do I stop my MacBook from ONLY booting in Safe Mode

I have a new Intel MacBook with 512 Mhz of Memory. My granddaughter loaded about 8 programs from the dock all at the same time. Now, the computer will only boot up in safe maode. Does anyone know how I can get the machine to boot up properly? And yes, I have turned it off and on normally to see if this would fix the problem - but no luck. Help!!
MacBook Mac OS X (10.4.8)

"Now, the computer will only boot up in safe
mode."
In my earlier response I assumed that you booted into
safe mode by holding down the Shift key during
startup.
Upon reconsideration, I'm wondering if you meant
instead that the computer boots into safe mode by
itself, without your holding down the shift key. If
so, this would indicate that the computer suspected
some inconsistency in the filesystem and is booting
into safe mode in an attempt to repair the damage.
This repair can take some time. Are you allowing it
10-20 minutes to finish the task?
If so, and it still won't reboot into regular mode,
then you probably should start the computer from the
Installation Disc by inserting the Disc before
shutdown and then holding down the C key during
startup.
Don't actually install anything, but use the menu at
the top to run DiskUtility on the hard drive. Tell it
to "Repair Disk".
Sorry I didn't see this post before I responded to your first one. Yes, this is exactly what is happening. I am not holding down any key to force it into safe mode - it's doing that all by itself. I will try the 10 - 20 minute repair time as you suggested. What will I see happening after this period of time has elapsed? Does it matter if my screen goes into "sleep mode" before the 10-20 minute time is up? And then, if this doesn't work, I'll try your other suggestion using my installation disc.
Thank you!!!!

Can only boot in Safe Mode -NVDA(Video): Channel exception! is this hardware or software and how much did it cost you to get it fixed out of warranty?

My iMac freezes and crashes and I get the above message in the kernel log. I have done a few reinstalls from time machine but it comes back.
I get to the point where I want to erase the disk and do a clean install but I get afraid that the kernel will panic during install/ I will lose the registration keys to software/ or that I am just wasting my time.
Has anyone truly fixed this? Is an erase and install going to help?
My first crash happened a week or so after updating to 10.6.8. I was watching videos in full screen mode. When I pressed esc it froze. (Sometimes the audio continues but the iMac is frozen.)
So I stopped use Chrome but it followed me to Safari. I like YouTube Videos and can't watch them in safe mode -no sound.
After installing from a time machine back-up and just re-installing my Mac will boot normally but it doesn't last long and I often can't even boot to CD. It sometimes crashes in the finder.
What's going on?
This computer is old but should have tons of life left- if you've been here how did you get out of this mess?
How much is it going to cost me to get my computer back?
I can't do a hardware test because I don't know where the original disks are but tech tools and the system profiler assure me everything is OK.
Any moral support is welcome.

It could be a failing drive or logicboard (GPU), it is old and has probably served you well, you can take to an Apple store and they will diagnose it for free, and give you your options, but it is old and are you willing to pay much money to have it repaired? You are probably better off replacing it.
There is some software for data ercovery such as Disk Warrior, but it's not cheap.
Or ask about this program
http://nwsinglespeed.hubpages.com/hub/Do-You-Know-About-Apples-Flat-Rate-Repair- Pricing
You can try shutting down and try a SMC reset
http://support.apple.com/kb/HT3964
and see if it will boot, if it does try to do a back up, but something sounds as though it may be in failure mode.
Good luck

How to install Windows Updates in Safe Mode with Networking

On my VISTA Business edition, I was getting BSOD (blue screen) so I booted the system in Safe Mode with Networking. But in this mode when I go to Start Menu-->All Programs-->Windows Updates, nothing happens. Please help.
Thanks..Nam

Steps:
1-Open command prompt with admin mode
Or Boot from DVD in command prompt mode.(This is what i experienced, able to show the safe mode menu)
2- Write this command "bcdedit /set {default} bootmenupolicy legacy" and click enter
3- You can now press F8 while Windows 8 starts in order to access Safe Mode and other Advanced Boot options.
