hi, im looking for bios update myself. did you happen to find or figure out where the updates can be downloaded from via the acer servers? the only ones i find are on european and russian sites and "im not going there"

I was planning to reinstall Windows 8.1 on my laptop. I did by using a usb flash drive by using the legacy bios boot mode because it will not boot from it on uefi. It Installed perfectly but every time it started up it will be in legacy bios. 2 days after I tried to start it up by came up with the message os not found. I have tried f2,f8, f10 and f12 neither have worked. I cannot access recovery. I hope there is a solution to this as soon as possible because I need my computer back by next week

Mine after update to Windows 10 I have this problems f12,f10,f2,del can't enter bios .second update give a few seconds the blue screen appear ,can't restore to win8 removed bios battery to reset bios settings to reinstall Windows ,now operating system not found .need help very badly .is there anyway to get to the bios .

How does one go about shorting g2101? I can see the little triangle shaped contacts under the ram, but I'm not sure what to do next. I've dealt with standard motherboard jumpers but nothing like this :) Any help would be appreciated.

I encountered this problem today. Acer Aspire V5 will not display BIOS menu, no matter how many times you press F2, or whether you remove the HDD or whatever you try. The BIOS on that laptop can only be called from Windows 8 or 10 (not 8.1) , by restarting in recovery mode (aka safe mode) by holding the shift key when hitting restart on windows. So if the computer doesn't boot into the HDD because of a miss-configuration of the BIOS, no luck for you.

Today I was fixing a laptop with windows 10. I accessed the BIOS menu as described above (not F2) , then disabled safeboot and enabled legacy boot support and changed the order to be able to boot from CD, as I wanted to boot the computer with a live Linux DVD. The computer rebooted and I could use the DVD, no problem.

Once I turned it off again and removed the DVD I got the fatal message error, OPERATING SYSTEM NOT FOUND. I played around and tried the usual tricks (windows installation media, fixboot, and all the usual command prompt things that you try in these cases). No luck.

So I had to figure out a way of accessing the BIOS menu. I removed the HDD and got a blank one, I put it in the computer and left it ready to install a fresh new version of Windows 8 (not 8.1) on it, but for that I needed the installation media (which I didn't have). While downloading an OEM DVD through a torrent client, I read this post.

I thought, if I remove the motherboard battery and clear the BIOS storage it might go to default settings and enable again UEFI boot with Safeboot. And it did indeed!!! Getting to the bios battery is a pain on this poorly built laptop: remove battery, remove a myriad of screws, unplug cables, remove motherboard and get to the battery. I removed the battery for 2 minutes, in the meantime I plugged the power switch cable to the motherboard and pressed the button for 10 seconds. Put all back together and voil!!! It works again.

So now I can finally cancel the 4 gb download of the Windows 8 OEM DVD. Though I believe installing a windows 8 on a fresh HDD (you need a spare one, of course), booting that one, then restarting in safe mode (recovery mode) and going to UEFI menu should also let you change BIOS settings again.

I am seeking out forums where this problem lies unsolved, I am creating an account specifically to share the solution as I have struggled myself with this and have not received any help other than having to send the device back to the manufacturers to replace (and losing whatever data was on it), even the company's technicians can't give me simple instructions how to reset/clear the corrupted BIOS, their solution was for me to travel to a country where a service Centre exists to have the device replaced under warranty, the ticket alone would be more than double the amount of the device..

3. Locate the connector that runs from the battery to the motherboard/circuit board, pull it free, it is usually a small flat white connector with 4 pins that can be pulled free, if yours is soldered you'll have to De-solder it.

4. Push the connector back in partially, the device should make a clicking noise from the speaker or the LEDs should flash briefly as it comes on for a split second and goes off again. repeat this just for good measure.

None of this worked as I successfully entered my BIOS several times and reset/restarted the device but it still wouldn't reset, every time you fail clearing the BIOS and the device doesn't want to boot, repeat step 4. trust me, without doing that first nothing wanted to happen when I tried entering BIOS again.

5. Place your usb drive in a usb port, as soon as you power on the device you need to hold a specific combination of keys, i would suggest a usb stick with a small led light that shows you when it is accessed so you'll know when it is working.

6. I had to immediately start holding Fn + R after powering on, keep holding the keys and watch the flash drive, it should start rapidly flashing. release the keys and wait for the system to reboot after a few seconds.

I don't know if this will work for resetting BIOS passwords or other kinds of obstacles keeping you from accessing the BIOS, but I don't see how it wouldn't work unless the passwords are stored somewhere else or something.

Worst case you can take out your BIOS battery from your motherboard for 10 minutes and while no power source connected to it press the power button for about 10 seconds, than place the small 3V battery back again. Now powering on will give you an error report with an option to either enter bios or boot up.

NON of this helped. I did try all of it before getting here. I even reprogram the bios with my special machine and nothing. So far the only thing it helped was booting with a w8/8,1 Core x64 dvd installation. By default most w8 bios had cd/dvd booting first than the hdd. The root of the problem is that you had your bios reseted to default somehow. GL!!

a good tip to know if your w8 computer came originally with 8 or 8.1 is to boot up the core version of each one and the one that does not ask for a key is the one. Also if you computer is originally w8 you can go ahead and install w10 and it will activate after changing in the bios the w8 key for the w10 key with no problem. I do it everyday even a year after the free upgrade is gone..

Then and ONLY then was I able to switch off the secure boot and boot to a USB stick and install the OS on a blank drive. This is a dismal design for a laptop. Acer should be ashamed of themselves for selling such garbage.

I have this problem also. My disk was already failing and i did replace my HDD, ending up with the "Operating System Not Found" error at the startup. No matter what f1-f12 you press you cant do anything. Tried everything, shorting the g2101, dismantling it just to remove that CMOS battery, even broke some of the screw locks at the joints, i even tried installing a windows 8 on my desktop to the new laptop HDD just to check if it will boot, but no luck. I almost smash this laptop, haha.

yet I solved this by downloading Windows Media Creation Tool from microsoft. just run it, select an OS, select a USB drive or Disk, its pretty easy and it will install the newest version from microsoft and make you a bootable windows installer. I selected windows 10, then it will download, just let it finish, then i put it in my acer v5 571 then press the power on, and Voila! it booted! then i proceeded with the formatting. from what i read is it makes an UEFI bootable disk.

the way I did solve my problem ( the fact that I get the message " operating system not found" and no way to enter the bios or to boot from cd-rom/DVD / USB new blank HDD or with OS on it did not work. so I was left with a laptop not booting any more !! the chance wanted that my brother in law had a ASUS x551 with windows 8-1 originaly installed from manufacture. the think is that both of them to replace the HDD need to be disassembled completely so I said what the heyk one more time !! so I put the hdd of the Asus in the Acer and what do you know it started !! w8 tuck 3-4 minutes to configure the new hardware ! and boot correctly so I made the change to do the boot in bios. I restarded in bios change it to legasy and replace the hdd Asus with a new SSD with w10 installed on it ( wich by the way did not want to boot in the previous situation, THIS TIME did boot !!
