There is most likely a recovery partition hidden on the hard drive. What is the make and model of your laptop?
Restart your computer then press the ‘F2’ key once the ASUS logo appears on the screen. You should see the System Information window of the BIOS setup utility with the current settings. Keep searching the settings until you get the option ‘Repair your computer’. Then select the ‘Repair’ option and click ‘Ok’ to continue with the repair process. Select the user name and password ***** you to log in on the following screen. Make sure your user account on has administrative rights. Then, type the password, or leave it blank and click ‘Ok’ to continue. Select the option, ‘ASUS Factory Image Restore’ at the bottom of that screen to repair your ASUS and get back to the original state.
Keep in mind this will most likely wipe your current files.
Where have you backed them up?
As long as they are backed elsewhere you are fine. Reboot again only this time try the F9 key.
What this will do is take you back to the original condition your laptop was in when you took it out of the box.
I doubt you will be able to access safe mode. The recovery discs should give you everything you originally had when you purchased it.
Since you installed Quicken, if you haven't backed that up you will lose the data. The recovery discs will re-install all of your programs and basically start you over. You can try safe mode by restarting, holding down the shift key while continually tapping the F8 key.
Another alternative is to have someone make you a system repair disc from another Windows 8.1 computer and boot from that. You would then be able to access safe mode from there.
You can also download the Windows 10 iso file and burn it to a DVD and attempt to re-install it?
How's it going?
I'll be away for a few minutes but will respond back as soon as I can.
