hi,
I recently installed a rogue video driver that was meant for win vista x64 on my win 8 x64 as i was having problem with the default one. It gave a warning that the os is not supported. But i ignored it and forced installed it through device manager. The screen blinked as usual when installing a video driver. But then i noticed that it was blinking infinitely without any display. Now i cant boot normaly as it starts blinking after boot screen without any display. I can remove the driver in safe mode but i have tried f8 it doesnt work. How can i boot into safe mode?
Sorry for mistakes i am typing this from an old java phone. Thanks.

Try SHIFT - F8 during BOOT sequence. It should let you in safe mode and there you can uninstall that driver. Vide0 drivers are not active in safe mode.

Thanks for replying. I have tried Shift + f8. It doesn't work. I have researched on this issue and from that i can conclude that windows 8 and 8.1 listens for boot interrupts just for few nano seconds and this makes almost impossible for a user to send a command into that time frame. Looks like the only option left is to get a windows 8 repair disc or its original installation disc as it gives the access to advanced boot menu. Please share any other suggestions if you have.

If you can boot with an 8/8.1 disk or usb you can try with this to enable safe mode: bcdedit /set {default} bootmenupolicy legacy

@countMIKE Thanks.

@genet You mean I can't access Advanced Boot Options from the recovery or installation setup? Then I think I can use the 'bcedit' command to enable F8. I would go and get the recovery or installation disc on a bootable pendrive on monday. Just need to access safe mode somehow.

Yes.

For example, you can get the selected "Refresh your PC", "Reset your PC" and "System Restore", but you can't start safe mode from the Startup Settings screen (formerly Advanced Boot Options), because you will not have the Startup Settings option if you booted from Windows installation media, system repair disc or recovery USB flash drive.

If you booted from a Windows 8/10 installation media or recovery USB flash drive, then you will not be able to boot into Safe Mode from the Advanced options screen, because you will not have the Startup Settings option (see screenshots below).

Advanced options without Startup Settings.png

Advanced options with Startup Settings.png

Tip   Tip
But if you can at least get to the Windows 8/10 logon screen, then you can start Safe Mode, see the instructions at this link. -> link


If Windows 8/10 does not start: How to boot into Safe Mode from the Windows 8/10 installation media or recovery USB flash drive.

- Start the computer from the Windows 8/10 installation media.
- Select Repair your computer (see screenshot below) > Troubleshoot > Advanced options > Command Prompt.

Safe Mode 1.png

-or-

- Start the computer from the Windows 8/10 recovery USB flash drive.
- Select Troubleshoot > Advanced options > Command Prompt (see screenshot below).

Safe Mode 2.png

Run one of the following commands:

- Safe Mode (see screenshot below):

bcdedit /set {default} safeboot minimal

- Safe Mode with Networking:

bcdedit /set {default} safeboot network

Safe Mode 3.png

Close the Command Prompt window and select "Continue - Exit and continue to Windows 8/10" (see screenshot below).

Safe Mode 4.png

You are now in Safe Mode (see screenshot below).

Safe Mode 5.png

Windows will continue to start in Safe Mode every time you reboot unless you undo what you did.

- Open the "Command Prompt (Admin)" (see screenshot below).

Safe Mode 6.png

- Run the following command (see screenshot below):

bcdedit /deletevalue {default} safeboot

Safe Mode 7.png

Nice to help because at the same time, I also learned new things and I learned to write better English (my English writing is very poor, but my English reading is better).
