Used live cd on windows 8 laptop.. "operating system not found"


I am in such a difficult situation here.. tested linux mint on my MOM'S laptop and now when i want to normally boot to windows 8 i get "operating system not found".. this shouldnt happen, why does all the weird linux complications happen to me? http://media.tumblr.com/tumblr_m9wa9brheA1r2qpgg.gif she still doesnt know, so you can imagine i am kind of nervous right now...help.

oh right.. in the bios i had to disable secure boot and switch from uefi to legacy before i could boot the live cd.

N.B: please tell me its an easy fix and that im not fu- ed.

Have you reenabled secure Boot and switched back to UEFI ?

I have found a few systems that require you to unplug ac and battery and then press power button a few times. Then power it up and test.

Have you double checked that all bios settings have been returned?


What live cd did you try?


Ask her to install a virtual machine to test linux. It is much safer but usually a live cd is very very safe. Not sure what happened here.

Any chance you installed linux somehow?

oh God thank God. PHEW that was close!.. the laptop didnt work with any of the known bios buttons.. but rather an small "Assist" button Sony put on the right top, i was about to give up and look for a recovery disk which i had no idea where it was and it seemed like an overkill, but then i got the idea to google the model and see how to bring up the bios because i couldnt believe things were THAT f-ed up (no bios= huge problem). changed it back to legacy and next thing i know is windows 8 is running..PHEW!

and that my friend is why win8 sucks along with their implementation of secure boot.

This is not an issue related to Windows 8 at all. You would have the same problem with a Linux system that is installed in UEFI mode.

Time to think about your own computer to play with. HINT!

If nothing else, get your mother to install a free virtual machine to let you test linux with. Be sure to use great care with her computer. That includes any downloads and installing.

Read the owners manual for how they expect you to recover from catastrophic failure.

Make backups of her data and programs.


Nothing worse than breaking someone's computer.
