Things used:

Sandisk Flash drive with windows installed onto it

I looked up many ways to fix my acer r3-131t, and all of them said to take out my cmos battery for 5-10 minutes and I did for 5 tries now. I even tried just running my computer without it, but the bios is still the same! My problem with the bios is that everything is greyed out even the load default setup button and I don't know what to do at this point. I tried reinstalling windows but whenever I connect the usb it says No Bootable Device, which I'm thinking means that my computer isn't finding it because of the boot menu settings which I can't access.

Please help! It would make my life so much better and easier! God Bless.

Hi,

You need a new CMOS battery because your system shows wrong date, go to the Main tab, set the correct time, then correct date(it's showing 01/01/2015 now), if you have to do it every time you turn on the laptop, you need a new CMOS battery.

OK, try and see any of the methods in this video of any help, BTW, I would strongly suggest you change the CMOS battery before trying anything.

You can also do the recovery in an alternative way..

There are two alt keys on the keyboard. If you look at the bottom row of keyboard you can see the one on the left side of space bar and the other on the right side of space bar. The alt key on the right side will be looking like alt, alt gr or alt car. Turn off the computer. Hold the alt key on the left and tap f10 continuously. It will go to repair mode. It will show you chose an option, continue, troubleshoot. If it is not going to repair mode, turn off the computer. Turn on the computer. Hold the right alt key ( alt gr or alt car or alt ) and then tap f10 continuously. It will go to chose an option continue and troubleshoot..

It will show you chose an option, continue, troubleshoot

Go to troubleshoot - click on reset this pc

click on keep my files ( only applications will be lost ) chose your account and type your password - click on local reinstall - click on reset

It will be in progress

If the keep my files option is not working

Go to troubleshoot - click on reset this pc – click on remove everything – click on local reinstall – just remove my files – click on reset

It will reinstall windows.

If the just remove my files is not working..

Go to troubleshoot - click on reset this pc – click on remove everything – click on local reinstall – Fully clean the drive – click on reset

It will reinstall windows.

Note: You can also go to chose an option , continue , troubleshoot by holding the alt key + tapping f10 or alt gr + tapping f10 on the keyboard while turning on the computer. Once you see the troubleshoot option, you can stop tapping the f10 and stop holding the alt key. Then you can try the keep my files and remove everything ( just remove by files and fully clean the drive ) by following the steps which was mentioned above.
