Safe Boot Vs Safe Mode

[Imke]

SafeMode starts Windows in a basic state, and uses a limited set of files and drivers. If a problem does not happen in Safe Mode, it means that the default settings and basic device drivers do not cause the problem. Observing Windows in Safe Mode enables you to narrow down the source of a problem, and can help you troubleshoot problems on your computer.

In Safe Mode, Windows has reduced functionality. The task of isolating problems is easier since many nonessential components are disabled, such as sound, third-party drivers and services, nonessential Windows services, and more. Corrupt software, drivers, or the installation of poorly configured software prevents Windows from successfully booting into normal mode.

When I rebooted the computer, my monitor gives a "signal out of range" error because I believe the video is being detected at a higher resolution than the monitor supports. How can I force Ubuntu to start up in a lower resolution so that I can adjust display properties. I've already tried editing the /etc/default/grub and un-commenting #GRUB_GFXMODE=640x480 line. I know in Windows, you can press F8 on boot to go into a safe video mode so I'm looking for the equivalent in Ubuntu.

To start Ubuntu into safe mode (Recovery Mode) hold down the left Shift key as the computer starts to boot. If holding the Shift key doesn't display the menu press the Esc key repeatedly to display the GRUB 2 menu. From there you can choose the recovery option.

first boot:

press the escape key to enter the startup menu then enter normally the os login manager , then restart

second boot:

press the shift key , it will redirect you to the gnu grub screen

I desperately need help getting out of safe boot! I started using it when my mac wouldn't boot normally, it was stuck in a blue screen, so I tried going to safe boot...but then I couldn't access the Internet, I couldn't use any third-party applications!

Here's the things I've done so far...I've used the terminal and tried resetting my PRAM, tried rebooting via single user mode and even reinstalled the OS setup and created a new admin. I was still stuck in safe boot.

My shift key is stuck due to a water spill. We were able to work around the problem of booting up by using a bluetooth keyboard. This is a good solution to have access the computer if that is the only damage.

I had the computer opened and looked at by a genius bar guy and he confirmed that the key was damaged by the water spill. So, what I'm trying to do is find a way to more effectively use it until our IT guy at work can find a replacement part.

I should have added. I did open an original question and someone directed me to an answer that sounds very promising (I left the computer at my office overnight so I haven't been able to test it) the suggestion is that holding the ESC key down while starting up will allow the computer to open normally. If it works I will report back.

Replacement parts can be obtained through a variety of places online - I generally recommend checking ifixit.com as they have teardown instructions and links to the necessary part(s) for your particular Mac.

Ok so, I installed zorin OS with the option of safe graphics. It restarts, but then it boots in normal zorin (black screen) so I can't install graphic drivers for my AMD video card. I mash the esc button but it boots into a shell or kernel thing. I mash the shift button and it still boots into normal zorin instead of the boot menu. Help please

Gday @Nezon ,

Welcome to our community!

Could please tell us how you wish to install Zorin? Dual boot or clean install?

Which Zorin OS? Core or lite or pro?

(Please adjust your profile to show your "Edition". saves us asking )

It seems your at the stage of trying or installing Zorin?

If so Select the top one " Try or Install Zorin OS "

I just finished installing Zorin OS with sage graphics (Didn't have amd drivers). I restarted my pc, but after mashing esc it goes into a GRUB shell instead of the boot menu, where i should have been able to edit how zorin os launched so I could install the right drivers.

Ok, let it startup to GRUB, ( No key mashing)

Can you select " Zorin "?

If yes, open to Zorin.

Once running then use " Software Updater " to help install needed item's ,

Once your Software Updater has loaded updates,

Click the setting button, & open Additional Drivers TAB.

You should see drivers listed, select your drivers needed then "Install". restart pc.

After attempting setting up Raspberry Pi bluetooth to be bluetooth receiver for stereo, now whenever I start it up I can't SSH at all, I can't use the desktop at all or CTRL+ALT+Fnumber key to get to a terminal.

I see a failed message on booting so I think last tweak broke bluetooth... but how can I possibly get to a root console to fix it again? Even in Shift recovery mode, Ctrl+Alt+F1 does not let me log in as it rejects the password. This is on up-to-date Pi3.

Instead of bypassing all the system can do, this tells init the runlevel is "S", and it can then do special things to support this case. I just tested this with my semi-ancient installation of Jessie.

I have a Windows server that will sometimes reboot into safe mode after updates. I'm working on that issue but what I'd really like to know is how can I check to see if Windows is running in safe mode or not.

According to this article, an environment variable called SAFEBOOT_OPTION is set to either Minimal or Network if the system is started in Safe Mode or in Safe Mode with Networking; otherwise, the variable is unset.

A test on the variable's value should do the trick; however, keep in mind that if the system is actually running in Safe Mode, it'll have no networking to begin with, so reporting its status could be... difficult.

A more useful way to determine if you're in safe mode of not is from: Microsoft Windows Internals: Microsoft Windows ServerTM 2003, Windows XP, and Windows 2000 by Mark E. Russinovich, David A. Solomon.

The Windows kernel scans boot parameters in search of the safe-mode switches early during the boot and sets the internal variable InitSafeBootMode to a value that reflects the switches the kernel finds. The kernel writes the InitSafeBootMode value to the registry value HKLM\SYSTEM\CurrentControlSet\SafeBoot\Option\Option Value so that user-mode components, such as the SCM, can determine what boot mode the system is in.

HKLM\SYSTEM\CurrentControlSet\Control\SystemStartOptions contains a string and if you are in safe mode there will be a "SAFEBOOT:???" within the string where ??? is MINIMAL or NETWORK. This gets updated on each boot.

I have a desktop Windows 10 x64 machine that's been working fine for months/years. It was automatically updated from Win7 last year. A couple days ago I replaced the 2x4GB DDR3 memory with 2x8GB DDR3. This seemed to work though for some reason it works at 800MHz instead of the 1600MHz that the memory supports. The BIOS shows mem freq 1600 as expected. But this is the smaller issue. The PC worked booted fine.When everything seemed to working as expected, I was still bothered by the slow startup and login times. Now with 16GB I had expected these times to improve.I installed Windows SDK performance recording tool and set it to record the boot sequence and restarted the PC. Windows failed to boot twice (UNEXPECTED KERNEL MODE TRAP) and went into the auto diagnostic repair mode. Restore just spins until I lose patience. I did manage to boot in safe mode and disable the recording. It did not help.Running sfc/scannow "did not find any integrity violations".

I also managed to uninstall the Windows SDK/Perf Rec (by restarting the MSI service) - to no avail.

I ran the Windows memory test, but when it's done it reboots, the reboot fails, and I never did see the results.

I replaced the new RAM with the original ones, but this did not make any difference (BIOS setting are as they were originally).

Did you install the new sticks of ram into the same slots on the motherboard that you removed the old ones from ? There should be a manual for your motherboard from the manufacturer showing you the order that ram should be installed.

Please configure Windows to generate complete memory dumps, then restart the system and reproduce the crash. When done, compress the memory dump, upload it to a safe location and pm me a download link. Also enclose logs collected by ESET Log Collector (it generates a zip archive).

Before I can do what you ask, which would require me to reinstall it (again) and figure out the mem-dump process, please take a look here, where I originally posted and where I was pointed to ESET as the/a cause. There's a zip file there with the dumps I did a couple of days ago. Please LMK if they're sufficiently informative.

I am in an VMWare environment & have a 2016 Server that seems to be having issues with some 3rd party SW that is keeping me from being able to login to the Server correctly. I would like to Boot the VM to Safe Mode. My understanding is that if I get the VM rebooting, click in the Window to get the Focus on the VM & hit F8 during the VM Post mode it will bring me to Safe mode Menu. What I actually get when I follow this procedure is Booting to Boot Manager, which does not help at all!!

I know this may be out there a bit, but when the vm is up, can you connect to it using PSTools via command line? Then possibly uninstalling the application via command line as per: -to-uninstall-a-program-on-windows-10-from-command-prompt/

I have a Proliant Microserver Gen8 running Windows Server 2012 R2. Our Anti-malware installed an update that causes the server to not boot correctly. In other Proliant Servers (DL380 Gen8 and 9, DL360 Gen8 and 9) I was able to get into safe mode (all through iLO) because the recovery utilites presented the option to restart in safe mode, however the Microserver does not present the same choices despite it having the same operating system.
