Windows Won't Start After 8.1 Update - Not Able To Boot In Safe Mode
May 12, 2014
Last night I updated windows 8.1 from windows 8. It got to the stage where it needs to restart so it done that started the configarations and once it reached 100% it restarted.
Since then what happens is when i press power on the samsung logo comes on the screen then the black screen with the windows picture then the bsod comes up for around half a second and it restarts. then it constantly does this.
The whole cycle only takes a few seconds.
Ive tried booting in safe mode but this isnt working so I downloaded kav rescue on another computer and saved it on a flash drive, But it wont boot off this either.
I recently tried to update my graphic driver through Windows Update and it caused the screen to go black. I thought I would be able to boot in safe mode and restore the changes, but it does not seem to be as easy as that in Windows 8.
I can access BIOS with F2, but nothing happens when I hold down or tap F8. I have tried to search around for a solution, but they are either not working, require the OS-CD or me to be able to log in somehow...
I can't boot into Windows 8.1 at all or even safe mode..I have tried startup repair etc etc ....I also tried the bcdedit trick to boot directly into Safe mode with the command prompt option no dice either..I would rather not do a refresh or reset pc..Matter of fact I have tried both options and even with a clean 8.1 disk I can't ....It gives me the error message remove cd or media and restart no matter whether i have the disk on or not. i think it might be a problem with the boot or something or its booting to the wrong device perhaps a USB ? i do have bitlocker on the drives and when i got to do a startup repair it asks for my key and i obv have it on other media which is my usb which won't read the key from it anymore..
how to boot into safe mode in this final RTM or Msdn version of win 8. I know that in the release preview version of win 8 you had to manually activate safe mode through command prompt...is this still the case in this version of win 8?
I cant log in, into my account, I was trying to customize my windows 8 themes, folder, appearance .etc
I watch a vid in youtube were it showed me to change a file named Shared32.dll
I am sure it was this file that cause it to kinda mess up... Icant boot safe mode because of this...
When I turn the computer on it goes to my log in and password title... but I try to log in , and it does nothing....It shows this "The User Profile Service failed the logon. User profile cannot be loaded". I tried to boot in safe mode but it doesn't show nothing ...
I cannot log in... so basically I am logged out forever...
SVF1521P2EB from PC world.Trying to use a recovery program I always use for all my laptops and desktops and have created a bootable USB Stick and also a DVD bootable disk. Both disk and usb work on all other systems but this Sony Laptop.
Have USB stick in the usb2 port not the usb3 port due to compatibility issues with backup/restore on usb3. The stick is a usb2. I have gone into bios and set usb and also tried dvd as first boot device. Will not boot.
Have tried the assist button on the laptop and the restore (boot from dvd/usb media) also does not work, as stated these both work on other laptops and desktops.
I have tried to find the boot option menu or safe mode startup. I have tried this by pressing various buttons each time on boot usually F2, Del, esc, F12, F10 on other systems and also F8 which does not appear to enable the laptop to start with a manual boot.
All I seem to achieve is the Vaio screen and straight to Windows8.
I do see the sony recognise the usb as the green light is flashing, no message of boot failure.
1) What is the boot option at startup to manually select a boot device.
2) How to boot into safe mode.
3) How to possibly rid the boot up screen displaying the VAIO logo.
4) Get the Sony to recognise either the bottable dvd or usb to backup the system without using the sony or built in miscrosoft bootup.
Final result should be a full image backup of the hard drive ona an extarnal harddrive/usb stick for future restoration.
Win 8.1 Pro x64. Got to the safe mode screen with the nine choices for start up method. 5 or F5 is supposed to restart with networking, but the connection isn't happening. Attempts to make it bring message that I have to start Windows normally.
One day, I rebooted, and then there was nothing. After Windows finished loading, there was naught but a black screen, and a cursor if I move the mouse quickly. This happens in safe mode as well, and on both my dedicated graphics card (an Asus AMD HD 6450 Silent) and my integrated graphics (Other than it is a Biostar A780L3G). When I try to refresh directly, with a fresh copy of Windows 8.1 installation media, it says it is invalid, despite it being x64, same as the installed version. When I try directly, it says the HDD is locked, and none of the guides I have followed to unlock it through the disk work. Also, I dont know if this matters or not, but when I try booting into safe mode, at first, when I move the mouse, in the corners, it says Safe Mode.
I have an Asus CM6730 PC, bought in October, which had Windows 8 installed on it.
Everything was fine, until I decided to install the upgrade to Windows 8.1.
After a week or so, my mouse started to freeze up randomly and the only way to log out of the PC was by holding the power button down for several seconds. The next day, I was working on the PC, took a phone call and the machine went into standby mode - but wouldn't come back on when I press a key / moved mouse.
At that point I decided to restore the machine back to factory settings. This was done successfully so I was back to Windows 8. However - my problems have got worse - and now I am at the stage where the PC wont even boot up in Safe Mode - the screen just goes black.
I have read up on a few sites and I believe it could anything from driver related - to a faulty motherboard.
My screen seems to have a grey filter overlaying it. See attached.
When i booted it in safe mode, the screen is showing the right vibrant colors. When i booted it back to normal mode, the screen is greyish but strangely the mouse is showing the correct white color.
I have googled across numerous website but none of them bring me closer to the issue. I have read the thread, Personalize Suddenly Greyed Out but this is not what i encountered. The options or buttons or selections did not grey out, it affects the screen only.
I cannot afford a system restore because i shared this laptop with my gf.
Does Windows 8 have a Safe Mode and were do I find it. the reason I ask this is because I have tried going into Safe Mode in Windows 8 by hitting the F8 key so I could run my virus scanner to see if there are any virus that it may not be finding under normal mode. But when I reboot my computer and try going into safe mode in Windows 8 nothing happens.
I was trying to get AMD drivers working properly so that FIFA would stop crashing. I read somewhere that installing the latest AMD Catalyst Beta with separate Intel drivers would work. I tried that, rebooted, and now I have a black screen after the Windows splash logo, with my mouse pointer visible if I move my mouse. So clearly something went wrong with the graphics driver installation.
No problem, I'll just simply boot into safe mode, uninstall the drivers, and experiment with some other drivers.But no. F8 doesn't work, I know. Shift-F8 doesn't either. So I got my installation media, surely there would be a way to boot into safe mode with it!
Here's what I get.
There's supposed to be a 'Startup Options' button here, but for SOME reason, it's not. I have no clue what to do. I cannot fathom HOW Microsoft managed to make booting into SAFE MODE such a puzzle for an end user.
Some more background: After a similar graphics driver adventure last week, I got into safe mode (phew), tried to uninstall AMD drivers. I got an error about how this the installer cannot run in safe mode (what?!). I tweak some registry key to get it working. It failed to uninstall properly. I rebooted, and then I was absolutely unable to get OUT OF safe mode. Nothing I did changed that, each and every time Windows booted to safe mode.
I can't remember the last time I had such a bad experience with a Microsoft product. backing up files in my C: drive and simply installing regular Windows 8 over this. BUT I can't access my C: drive via Ubuntu because Windows has LOCKED that partition because of it's fast-boot nonsense.
I have Lenovo laptop with Windows 8.1. I enabled safemode and restarted my laptop.on Login screen, it asks me to enter microsoft account password and my wifi is disabled. When i enter the password, it says password is incorrect. How do I login?
My computer lock-up after 2 secs log into windows (due to drivers problem). I need to boot my computer to safe mode directly and use driver sweeper to fix the problem. However, I'm not able to get into safe mode. (F8, Shift+F8) doesn't work neither.
My dad restored his computer to its factory settings while Windows 8 was in safe mode, attempting to remove a virus, and now every time the computer is booted, an error message appears, saying that Windows is not able to install because safe mode is still active. Is there a way to disable safe mode so that Windows set up can be continued?
now that windows 8 no longer has safemode or the old F8 menu how do you remove a stubborn virus or malware that after booting attepts to lockout the user and prevent other programs running. back in older versions you could boot into safemode or boot from a bootdisk and cleanup, so now whats the procedure ?
I am using Windows 8.1 with all the latest updates.
I'm trying to get into safe mode, but when I do it is only a black screen with in each corner it says "Safe Mode" and the whole screen blinks every few seconds resetting the cursors position. The cursor and text are only visible when I am moving the mouse, otherwise it's all black. I can't do any button combinations like CTRL ALT DEL or anything.
Normal mode works fine, and I can't think of any viruses/malware that work allow you to work in normal... but not safe mode.
I have all my Windows 8 options disabled (Windows 8 mode, fast boot, secure boot) to see if it was those but to no avail.
Every time I try, I have to go into safe mode. It sticks, so I can't just reboot/reset and go back into normal mode. I have to go into the emergency cmd and do bcdedit to delete the safeboot value.
I usually clean my PC every so often, the same with OS re-installation but nothing is wrong with the normal mode and the OS still seems quite fast with the SSD.
I have never seen safe mode function, this is the first attempt at running it in safe mode. What could cause this? I can't get into safe mode but can get into normal mode...
I had to boot into safe mode for virus removal and now all it will do is boot and start safe mode, then reboot again. It just keep doing it over and over. This is a new upgrade to a windows 7 pro OS and I am using 8 pro.
Cannot boot in normal mode. Tried to do that by going into the advanced repair and doing a normal startup, just keeps going back to safe mode and as soon as the screen starts to open it reboots.
